| 02:25.11 | f1shhead | looks like the lcd is custom for ericsson |
| 02:25.26 | ohsix | its unusual for an lcd not to be a custom part |
| 02:25.41 | f1shhead | well it just means this old cell phone is a worthless pile of parts |
| 02:26.17 | ohsix | i could have told you that before you took it apart :P |
| 02:27.05 | f1shhead | oh well I can use it as a battery charger for the lithium pack |

| 04:21.34 | jbevren | joe_bleau: cool |
| 04:21.37 | jbevren | url? |
| 04:21.46 | jbevren | man' |
| 04:21.50 | jbevren | the string on the stylus is too short |
| 04:21.51 | jbevren | hehe |
| 04:22.20 | jbevren | about 1cm more would be perfect :D |
| 04:26.15 | jbevren | no url? :) |
| 04:26.35 | joe_bleau | I'm looking for it, standby |
| 04:26.38 | jbevren | ah ok |
| 04:27.53 | jbevren | I'm beat. hehe |
| 04:27.58 | jbevren | spent 3 hours driving home |
| 04:29.09 | joe_bleau | Start at: http://forum.sharpsma.com/viewtopic.php?t=345 |
| 04:29.31 | joe_bleau | Follow the reply for the internal validation board link |
| 04:29.47 | joe_bleau | Click on "Share" in the left menubar |
| 04:30.02 | joe_bleau | And I think you should see it. |
| 04:30.24 | joe_bleau | There's an NDA note on it, so I don't want to direct link. |
| 04:30.42 | joe_bleau | But it appears that you can get there using public links, and it was placed by a Sharp employee. |
| 04:31.01 | jbevren | it's a schematic(?) |
| 04:31.27 | joe_bleau | The link is for a schematic, but if you hit the "Share" button, you'll see that there are other docs as well. |
| 04:31.37 | joe_bleau | a BSP, the user's manual, and some schematics. |
| 04:31.49 | jbevren | I see |
| 04:33.14 | joe_bleau | You may need to register with their BBS to gain access...I don't know. |
| 04:33.36 | jbevren | I'm downloading the third file :) |
| 04:36.15 | jbevren | oh |
| 04:36.17 | jbevren | it has an emac? |
| 04:36.19 | jbevren | mmm |
| 04:36.25 | jbevren | wonder if its pads are extended :) |
| 04:36.59 | joe_bleau | That's why I was asking if it already had a PHY |
| 04:38.11 | jbevren | heh |
| 04:38.15 | jbevren | none vsible |
| 04:38.17 | joe_bleau | BGA or TQFP? |
| 04:38.24 | jbevren | unless its a OB |
| 04:38.26 | jbevren | er COB |
| 04:38.29 | jbevren | the cpu's bga |
| 04:38.32 | joe_bleau | ok |
| 04:38.43 | jbevren | tomorrow eve I'll snap a shot of the board |
| 04:39.19 | joe_bleau | see the port c boot select stuff? |
| 04:39.32 | jbevren | havent read taht far yet |
| 04:42.05 | jbevren | anything related to the labeled pads on the board? |
| 04:43.28 | joe_bleau | Are the labelled pads the "A16, A15, A4" stuff on the Wiki? |
| 04:43.59 | jbevren | yeah |
| 04:44.18 | joe_bleau | Boot control looks at port c 7:4 |
| 04:44.35 | jbevren | bear also in mind that the pad labels may be locations in the bga layout |
| 04:44.51 | jbevren | for example. T1, T3 |
| 04:44.51 | joe_bleau | Right. The charts shows that those pins are at grid position |
| 04:44.56 | jbevren | ahh ok |
| 04:45.10 | jbevren | I haven tlooked at the charts yet |
| 04:45.14 | joe_bleau | R5 T4 P5 and R4 |
| 04:45.27 | joe_bleau | which is also A20-A23 |
| 04:47.24 | f1shhead | this old cell my mom threw away but I savd |
| 04:47.30 | f1shhead | you can load midi to it from windows |
| 04:47.35 | jbevren | fish: cool |
| 04:47.37 | f1shhead | and it looks like small games too |
| 04:47.42 | f1shhead | I guess it has a use after all :P |
| 04:47.43 | jbevren | joe_bleau: the lcd controller only drives active lcds eh? |
| 04:47.49 | f1shhead | even if it's useless for parts or cell |
| 04:47.56 | jbevren | fish: probably java games yeah |
| 04:49.15 | joe_bleau | Not sure which UART is bootable. |
| 04:49.46 | jbevren | the pads seem to be for uart0 |
| 04:50.02 | joe_bleau | Hopefully that's the one it'll boot from |
| 04:51.15 | f1shhead | wow cool |
| 04:51.27 | jbevren | the pixter does have some sort of nonvolatile memory |
| 04:51.42 | jbevren | I dont know if its ram, I havent removed the batteries.. at any rate, you can save some prefs and one drawing |
| 04:52.21 | jbevren | usb interface.. |
| 04:52.28 | jbevren | (page 481) |
| 04:52.42 | joe_bleau | Yep. Device only, right? |
| 04:54.32 | joe_bleau | I2S, so it can do audio. Does the pixter have a DAC? |
| 04:54.44 | jbevren | the pixter has audio |
| 04:54.55 | jbevren | it plays little tunes and noises while you draw and play the games |
| 04:55.19 | jbevren | hm |
| 04:55.25 | jbevren | wonder what code is in the internal boot rom |
| 04:55.47 | joe_bleau | I don't see any mention in this book |
| 04:56.13 | jbevren | oh |
| 04:56.16 | jbevren | the dac is external |
| 04:56.22 | jbevren | check the wiki. I cant get the whole chip ID |
| 04:56.32 | jbevren | <PROTECTED> |
| 04:56.44 | f1shhead | holy crap |
| 04:56.51 | f1shhead | it does play java games you can get |
| 04:56.53 | f1shhead | wow |
| 04:57.32 | f1shhead | http://ringtones.mobilefun.co.uk/java-games/sony-ericsson_t306/ |
| 04:57.34 | f1shhead | wow |
| 04:58.01 | joe_bleau | I'm thinking the '520 book might be older and have some UART boot info |
| 04:59.29 | f1shhead | whoa |
| 04:59.42 | f1shhead | I think my nokia tracphone can do java games too |
| 05:00.29 | jbevren | uart0 can dma |
| 05:00.29 | jbevren | heh |
| 05:01.01 | joe_bleau | No help |
| 05:01.09 | joe_bleau | I did DMA UARTs on the JB. |
| 05:01.38 | joe_bleau | Had it dump the boot rom, and it continued to TX while I was futzing around in the debugger with the CPU halted |
| 05:03.35 | jbevren | :X |
| 05:03.50 | jbevren | I need to hit that sleeping device |
| 05:04.39 | joe_bleau | later |

| 05:05.23 | jbevren | and on that note I"m out :) |
| 05:05.28 | joe_bleau | too bad. |
| 05:05.43 | jbevren | hopefully later pixters have A1 silicon |

| 13:58.38 | agaffney | he had been fairly well behaved lately |
| 13:59.59 | jbevren | prpplague: btw, the manual doesnt say anything about pixter color carts, but it does mention that the adapter will allow pixter b/w carts to work |
| 14:00.57 | prpplague | jbevren: hmm, from what i read all of the old carts worked |
| 14:01.13 | prpplague | agaffney: yea well i was reading through yesterdays log and was not too happy |
| 14:04.40 | jbevren | prpplague: you might be right |
| 14:04.49 | jbevren | it doesnt say they dont. Do they share a common expansion slot layout? |
| 14:06.05 | prpplague | yea thats what i gather |
| 14:06.13 | prpplague | jbevren: one sec let me get the pr page |
| 14:15.21 | jbevren | the adapter is only mentioned in passing, in the intro page |
| 14:15.28 | jbevren | it notes that it'll play any b/w software |
| 14:16.11 | prpplague | jbevren: yea the adapter is for the b/w software which has a different bus |
| 14:17.52 | prpplague | "Measuring 7-by-5 inches, with a 3.9-inch touch-sensitive screen and attached stylus, this new device can play the earlier Pixter software cartridges" |
| 14:17.59 | prpplague | http://tennessean.gns.gannettonline.com/apps/pbcs.dll/article?AID=/20051229/TECH0602/51229004/1011/tech0602 |
| 14:18.18 | jbevren | technically that description is right |
| 14:18.25 | jbevren | its like buying a stereo tv and vcr combo |
| 14:18.30 | jbevren | do you get a stereo vcr? :) |
| 14:18.39 | jbevren | :D |
| 14:18.47 | prpplague | "Pixter Multi-Media System is backward compatible with previous Pixter titles" |
| 14:18.54 | prpplague | http://www.scholastic.com/earlylearner/parentandchild/2005picks_tech.htm |
| 14:18.57 | jbevren | hehe |
| 14:19.12 | jbevren | and it is, just not with the color series ( I think ) |
| 14:19.37 | jbevren | if b/w and color have different buses, I imagine it would need two adapters |
| 14:19.37 | prpplague | i serious do not think so |
| 14:19.52 | prpplague | as for one thing several of the articles mention that there are over 100 titles available |
| 14:19.59 | jbevren | if its the same connector, the adaptor might be able to recognize the pixter cart by looking at the lines |
| 14:20.04 | prpplague | only 15 of the titles taht are available are b/w |
| 14:20.08 | jbevren | s/adaptor/adapter/ |
| 14:20.30 | prpplague | jbevren: the LH75411 and the LH79524 are very similiar |
| 14:20.41 | prpplague | jbevren: and should run identical code |
| 14:20.53 | jbevren | I thought the old pixter was 8bit |
| 14:20.55 | prpplague | jbevren: so i would see no reason not to make it compatible |
| 14:21.02 | prpplague | jbevren: it is |
| 14:21.10 | prpplague | jbevren: there are actually four models |
| 14:21.13 | jbevren | but it has a 32bit arm? |
| 14:21.27 | prpplague | jbevren: pixter, pixter 2.0, pixter Color , and Pixter multimedia |
| 14:21.33 | jbevren | ok.. |
| 14:21.36 | prpplague | jbevren: the pixter and pixter2.0 are 8-bit |
| 14:21.41 | jbevren | ah ok |
| 14:21.50 | jbevren | so the pixter color might have the same expansion port |
| 14:21.54 | jbevren | (as the multimedia) |
| 14:21.58 | prpplague | jbevren: the Pixter Color which is what the wiki page is on (miss named) is about the ARM based devices |
| 14:22.03 | prpplague | jbevren: correct |
| 14:22.10 | jbevren | now I understand :) |
| 14:22.32 | jbevren | let me catch up on tickets here at work, and I'll count pins on the port |
| 14:22.40 | prpplague | ok |
| 14:22.42 | jbevren | it'll be a while :P |
| 14:22.45 | jbevren | stupid mondays |
| 14:23.01 | prpplague | yea |
| 14:25.25 | jbevren | Oo we found a new way to alienate and drive clients away |
| 14:25.46 | jbevren | if a single script causes an issue we move the account to another server and require that they upgrade their service |
| 14:25.51 | jbevren | I'm glad I'm not hosted with us heh |
| 14:26.32 | prpplague | hehe |
| 14:28.05 | jbevren | granted, we -do- need to do something about the $5 account that is causing outages for 1100 other accounts |
| 14:28.20 | jbevren | but I think the solution may be better to -not- allow 3500 domains on one system heh |
| 14:31.17 | prpplague | hehe |
| 14:41.14 | sunrunner20 | 3500 domains on ONE system o.0 |
| 14:42.04 | agaffney | that does seem a tad excessive |
| 14:42.25 | sunrunner20 | better be like a quad opteron or something... |
| 14:43.25 | sunrunner20 | i spec'd a quad dual core opteron a while back |
| 14:43.31 | sunrunner20 | only $13 |
| 14:43.36 | sunrunner20 | k |
| 14:45.24 | agaffney | oh is that all? :P |
| 14:46.28 | sunrunner20 | :p |
| 14:46.37 | sunrunner20 | considering each cpu is $2000... |
| 14:46.45 | sunrunner20 | almost that anyway |
| 14:47.01 | sunrunner20 | dual core 8xx cpus are EXPENSIVE... |
| 14:47.06 | agaffney | yeah, I bet |
| 14:47.12 | agaffney | a 165 is only ~$350 |
| 14:47.28 | sunrunner20 | i love those cpus |
| 14:47.35 | sunrunner20 | they are better than the X2 series |
| 14:47.49 | agaffney | isn't the only real difference more cache? |
| 14:47.58 | sunrunner20 | there is no spec differance |
| 14:48.00 | agaffney | I've got a X2 4200+ in my home workstation |
| 14:48.04 | sunrunner20 | but |
| 14:48.13 | sunrunner20 | the opteron's overclock a whole lot better |
| 14:48.16 | agaffney | and a 4400+ in a thin client server I've got running here at work |
| 14:48.23 | agaffney | well, I don't overclock |
| 14:48.38 | sunrunner20 | 200mhz is nothing |
| 14:48.45 | agaffney | I like my processors to have a lifetime of more than 1.5 years :P |
| 14:48.49 | sunrunner20 | rotflmao |
| 14:48.51 | sunrunner20 | nope |
| 14:48.58 | sunrunner20 | overclocking has almost no effect on lifetime |
| 14:49.05 | sunrunner20 | maby one less year |

| 14:49.36 | sunrunner20 | ducks indeed |
| 14:49.40 | sunrunner20 | that has no logical basis.... |
| 14:49.45 | jbevren | theyre furnaces |
| 14:49.50 | jbevren | dead fan = fire |
| 14:49.59 | jbevren | I watched an xp cook a fan once heh |
| 14:50.05 | jbevren | melted the plastic right down into the heatsink |
| 14:50.05 | sunrunner20 | lol |
| 14:50.18 | sunrunner20 | ;you mean a thermaltake heatsink? |
| 14:50.29 | jbevren | stock amd HS/fan |
| 14:50.32 | sunrunner20 | rotflmao |
| 14:50.35 | sunrunner20 | obviously not |
| 14:50.42 | jbevren | we packaged the whole motherboard and sent it to amd |
| 14:50.43 | jbevren | heh |
| 14:50.46 | sunrunner20 | becuase the stock hsf does a very good job |
| 14:50.51 | jbevren | it does |
| 14:50.56 | jbevren | but the stock fans, for a while, were crap |
| 14:51.06 | jbevren | the bearings would go out after about 4 months |
| 14:51.31 | sunrunner20 | i'm suprised my abit nb HSF lasted almost a two years |
| 14:51.32 | jbevren | you can tell me we didnt put the thermal paste on right either. heh |
| 14:51.37 | jbevren | it had to be on right to melt that fan |
| 14:51.48 | sunrunner20 | what make you think i'd say that |
| 14:51.52 | sunrunner20 | thats something a lamer would say |
| 14:51.55 | jbevren | amd tried to :) |
| 14:52.02 | sunrunner20 | rotflmao |
| 14:52.05 | jbevren | "you didnt put the heatsink on right" heh |
| 14:52.07 | sunrunner20 | did they speak english |
| 14:52.14 | sunrunner20 | with a english accent |
| 14:52.21 | jbevren | they typed english well enough |
| 14:52.40 | jbevren | in the end, they blamed the motherboard's vrm |
| 14:52.44 | jbevren | heh |
| 14:52.50 | jbevren | cause ti sure wasnt their crap fan dieing |
| 14:53.29 | jbevren | prpplague: down to one page full of tickets now heh |
| 14:53.29 | sunrunner20 | shit like that is when you send a link to a digital picture of the problem |
| 14:54.33 | jbevren | we sent the whole assembly undisturbed for their reference |

| 16:16.37 | jbevren | I bet that one is hehe |
| 16:17.34 | prpplague | jbevren: all of the parport ones are pretty much the same, only difference is the pins used on the parport |
| 16:17.53 | prpplague | jbevren: you can usually change the definitions in the header of the jtag app |
| 16:18.24 | jbevren | ah |
| 16:18.29 | jbevren | I'll have to ring out the pins then |

| 16:25.40 | jbevren | http://www.nuhorizons.com/products/digilent/jtag-cable.html |
| 16:25.48 | jbevren | digilent only has it in an index with an 'add to cart' link |
| 16:26.02 | jbevren | nothing inside the hood, the buffers must be on the plug end |
| 16:26.14 | jbevren | that's wrapped in a heatshrink tube heh |

| 18:03.54 | prpplague | Chocobo: maybe i miss read the log |
| 18:04.26 | Chocobo | He was upset about someone... he has always been helpful to me. But if he was banned, there must be a reason. |

| 18:05.29 | jbevren | he doesnt know that we can legally RE this stuff if we're doing it to increase interoperability |
| 18:05.30 | prpplague | like mattel doesn't already know |
| 18:06.01 | prpplague | jbevren: not to mention the fact that mattel is in violation of the GPL on more than a dozen places with the juicebox |
| 18:06.17 | jbevren | yep |
| 18:06.23 | agaffney | where at? |
| 18:06.37 | jbevren | juicebox uses uclinux |
| 18:06.38 | prpplague | the sd/mmc driver, the lcd driver, the nand driver |
| 18:06.40 | jbevren | uclinux is gpl |
| 18:06.59 | prpplague | the software that is shipped on the cd contains atleast 6 known GPL violations |

| 18:10.04 | jbevren | there's a DAC IC |

| 18:10.13 | jbevren | er wiki |
| 18:10.15 | Chocobo | ok |
| 18:10.28 | jbevren | one of the IC's has some of its chip ID covered by expoxy spill on mine |
| 18:10.29 | prpplague | Chocobo: http://www.elinux.org/wiki/PixterMultimedia |
| 18:10.43 | prpplague | jbevren: yea i saw your post |
| 18:11.00 | prpplague | i still can't believe they used a lh79524 |
| 18:11.16 | prpplague | jbevren: you know it has usb host and a 10/100 mac right? |
| 18:12.47 | jbevren | I do now that Ive skimmed the datasheet heh |
| 18:13.48 | prpplague | should be able to hack it nicely |
| 18:13.50 | Chocobo | is the lh79524 good? |
| 18:14.18 | prpplague | Chocobo: good is a relative term |
| 18:14.36 | Chocobo | ok, why can't you believe they used it? |
| 18:14.44 | prpplague | Chocobo: lets just say, putting a lh79524 in the pixter, is like putting a harley engine in a moped |
| 18:15.38 | Chocobo | ahhh, sweet. guess I should pic one up. I bought the crappy juicebox the other day... maybe I will just start with the pixter |
| 18:15.46 | prpplague | Chocobo: hehe |
| 18:16.08 | prpplague | Chocobo: juicebox is a good device to hack, probably not something most people want to learn with though |
| 18:16.24 | Chocobo | What do you recommend starting with? |
| 18:16.40 | prpplague | Chocobo: depends on what you want to accomplish |
| 18:16.58 | prpplague | jbevren: when are you gonna get some pics of the board up? eh? |
| 18:17.38 | Chocobo | I dont know what I want to do. I am not sure if I want to run linux on the device, or just stand alone code. |
| 18:17.38 | jbevren | prpplague: I have this thing, its called a job heh |
| 18:18.02 | prpplague | jbevren: quit, you don't need money |
| 18:18.39 | prpplague | Chocobo: you obviously have some reason to even start hacking a device right? you have something in mind you want to accomplish right? |

| 18:19.11 | jbevren | if I dont go buying pixter multimedia's :) |
| 18:20.05 | Chocobo | Not really, my back ground is something like this... I have a couple of degrees (Electrical Engineering B.S., and and Computer Engineering M.S.) and they are great for academics, but they don't tend to help too much when it comes to hacking little devices... but I sure think it would be a cool thing to do. |
| 18:20.25 | Chocobo | I shouldn't say the degrees won't help me... I am sure they will, but only after getting started. |
| 18:21.01 | Chocobo | What sort of things do people do once they "hack" the device? |
| 18:21.33 | prpplague | Chocobo: well thats just it, 99% of the stuff i hack is for education. |
| 18:21.50 | Chocobo | That is good enough for me.. just being able to say "Yeah, look at this" |
| 18:21.52 | prpplague | Chocobo: imho the whole purpose of hacking in expensive devices is to gain experience |

| 18:23.33 | Chocobo | Alright, I was thinking of that. What do you recommend for architecture? ARM? |
| 18:23.50 | prpplague | Chocobo: depends on how comfortable you are with developing |
| 18:23.57 | Chocobo | I was looking at olimex.com today... they have a TON of development boards. |

| 20:07.29 | prpplague | the should perfome the same, the only difference is the fact that the -s is implement as a soft core |
| 20:07.51 | jbevren | and therefore, max clock speed is limited by your CPLD technology |
| 20:08.24 | prpplague | not really, the arm7tdmi performance is about the same |
| 20:08.32 | prpplague | jbevren: almost all new arm cores are -s |
| 20:08.37 | jbevren | relative to the clock speed |
| 20:08.55 | jbevren | I mean, if you stick the core in a slow PLD, you'll get (arbirtrarily) 50mhz, while a fast PLD will get you 100+ |
| 20:09.17 | jbevren | places like cirrus etc use VLSI though |
| 20:09.19 | jbevren | hehe |
| 20:09.22 | jbevren | er not vlsi |
| 20:09.33 | jbevren | whats the other term for a mask-generated IC :) |
| 20:09.36 | jbevren | you know what I man |
| 20:09.38 | jbevren | =mean |
| 20:09.40 | jbevren | stupid mondays |
| 20:10.54 | prpplague | jbevren: well its not that simple |
| 20:11.09 | prpplague | jbevren: the CPLD's you are talking about are custom devices |
| 20:11.23 | jbevren | ;nods |
| 20:11.28 | jbevren | ok |
| 20:13.43 | prpplague | yea that guy had no clue |
| 20:16.23 | jbevren | so he's worse than me eh? :) |
| 20:17.38 | prpplague | jbevren: there are 3 types of computer ppl in my book |
| 20:17.51 | prpplague | 1) someone who knows nothing and will tell you he know nothing |
| 20:18.01 | jbevren | I try to be that type :) |
| 20:18.06 | prpplague | 2) someone who know alot and will tell you he knows only a little |
| 20:18.19 | jbevren | 2 is closer to me, but there are huge gaps... lol |
| 20:18.30 | prpplague | 3) someone who knows only a little and will tell you he know alot |
| 20:18.36 | prpplague | #3 is freakin dangerous |
| 20:18.39 | jbevren | 3 is my employer, verbatim :) |
| 20:21.19 | jbevren | I try to be 1 irl cause too many people start asking me dumb questions |
| 20:21.35 | jbevren | like this guy at the store kept asking me questions about midi |
| 20:21.48 | jbevren | when he was having problems with a standard soundcard |
| 20:21.48 | jbevren | hehe |
| 20:22.40 | prpplague | hehe |
| 20:22.59 | prpplague | jbevren: you find the jtag yet? |
| 20:23.09 | prpplague | jbevren: on the pixter-mm |
| 20:23.45 | jbevren | I have this thing, its called a job... hehe :) |
| 20:23.53 | jbevren | :D |
| 20:24.02 | jbevren | I'll photo it in about a half hour tho |
| 20:24.06 | jbevren | that'll be my lunch hour |
| 20:24.11 | prpplague | ahh ok |
| 20:24.17 | prpplague | i'll be heading home shortly |
| 20:24.20 | jbevren | if it were tuesday, I might have time to poke |
| 20:24.24 | jbevren | but mondays are always bad |
| 20:24.41 | prpplague | porblem with living on an island |
| 20:25.12 | jbevren | nod |
| 20:25.28 | jbevren | I need to look up the pads on the board against the ball layout on the IC |
| 20:25.30 | jbevren | maybe some are jtag |
| 20:26.21 | prpplague | jbevren: yea they will probably be grouped together |
| 20:26.29 | prpplague | jbevren: a set of 5 |
| 20:26.29 | jbevren | nod |
| 20:26.33 | jbevren | lessee |
| 20:26.42 | jbevren | they werent in a row, but a number of them were in close proximity |
| 20:26.47 | jbevren | <PROTECTED> |
| 20:26.58 | prpplague | jbevren: gonna be TCK, TDO, TDI, TMS |
| 20:27.05 | jbevren | and ground |
| 20:27.14 | prpplague | might have a nTRST grouped as well |
| 20:27.16 | jbevren | need a vcc somewhere for the adapter too :) |
| 20:27.31 | prpplague | jbevren: well you should be able to grabe vcc and vdd easily from several spots |
| 20:27.40 | jbevren | yep |
| 20:27.49 | jbevren | like any pad marked vcc on the perimiter |
| 20:27.56 | jbevren | er.. spelling check heh |
| 20:28.09 | prpplague | jbevren: really interested in the jtag |
| 20:28.11 | jbevren | the ports and connections aside from the expansion port are all pretty well labeled |
| 20:33.34 | prpplague | yea, i suspec that the are the same |
| 20:33.43 | prpplague | we should be able to get linux running pretty quick |
| 20:34.00 | prpplague | i've already started looking at doing a ram upgrade |
| 20:34.54 | jbevren | some of the pins are labelled A19 etc.. but I suspect those are grid locations, not address bits :) |
| 20:35.00 | jbevren | uclinux is doable in 4M |
| 20:36.27 | prpplague | jbevren: yea but why stick with uclinux when you have an mmu |
| 20:36.39 | prpplague | jbevren: you could do linux in 4 |
| 20:36.52 | prpplague | jbevren: but not x or anything |
| 20:37.01 | prpplague | jbevren: could do microwindows |
| 20:37.14 | jbevren | tiny-x is a no-go? |
| 20:37.22 | jbevren | I dont know how big/small tinyx is |
| 20:37.46 | prpplague | jbevren: its not the size its the memory usage |
| 20:37.58 | jbevren | ah |
| 20:37.58 | prpplague | jbevren: you need atleast 8 and really 16 |
| 20:38.00 | jbevren | duh. hehe :) |

| 22:28.41 | jbevren | enough said |
| 22:28.48 | jbevren | maybe I'll take a picture of the lcd daughterboard later |

| 23:37.21 | r2d2 | alright, should be good then, probably won't have anything on pci, and just a cf card on ide |
