22:12.30prpplagueflyback: you might me able to help me for once dood
22:12.46prpplagueflyback: you got any pc sdram memory? 64mb?
22:18.50*** join/#edev redblue (i=star@ppp060.108-253-207.mtl.mt.videotron.ca)
22:29.44flybackactually yeah a whole pile
22:29.47flybackheh
22:32.09prpplagueflyback: mind giving me some of the chip numbers on them
22:32.18flybackabsolutely give me a second
22:33.27flybackchip id
22:33.29flyback?
22:33.44flybackok
22:34.00prpplagueyea
22:35.31flybackthis is from there
22:35.36flybackcouldn't find my damn strap

22:37.39flybacksingle sided 4 chip
22:37.47prpplagueflyback: you sure there are only 4 chips on that first one?
22:37.53prpplagueflyback: that would only be 32mb

22:38.51prpplaguei think thats 32mb
22:39.20flybackok here is another micro
22:39.29prpplagueok
22:39.44*** join/#edev davidc__ (n=davidc__@S01060002b360aacd.vc.shawcable.net)

22:40.18flybacktg  -8e b
22:40.30prpplagueyea that one fits as a 64mb
22:40.35prpplagueok thanks thats enough
22:40.38prpplagueflybackthanks
22:40.47flybacknp glad I could help for once
22:41.04flybackwhat you trying to do? find low desnity sdrams for a project?
22:41.18prpplaguejust getting a general idea of what chips are used
22:41.23flybackah ok :)
22:41.41prpplagueflyback: you could use one of those chips to upgrade the pixter
22:41.45prpplagueflybackor juicebox
22:41.52flybackhmm
22:42.45flybackyeah I guess there is actually a bit of a business in chip salvage cause of so many existing projects and stuff needing pc66/100/133
22:43.39flybackyeah but wouldn't that 64 meg with 8 mean each chip is 8
22:43.50flybackso it wouldn't be a upgrade for the juicebox if it already has 8
22:44.14prpplagueflyback: yea, i was just using the 64mb as a common place
22:44.34flybackanything bigger I still need for pc's ;)
22:44.36prpplagueflyback, but the juicebox only is using them as a x16, so you could add another bank
22:44.47flybackalthough if I find a defintye project I might do ti
22:44.50prpplagueflyback: pixter upgrade would be even bigger
22:44.56flybackhjehehe
22:45.18flybackI was actually starting to work on stuff like this
22:45.25prpplagueflyback: the laptop versions are similiar, thats what i probably will use with the pixter
22:45.26flybacklearning how memory upgrades work etc
22:45.41flybackwas going to try to upgrade a old 286 and printer
22:45.45flybackand work my way up from there
22:46.07flybackheh I have edo chips from a dead laptop that look like sdram chips
22:46.11flybacksame flat packaging
22:46.22flybackwhatever the heck it's called
22:47.20flybackI guess that's still tsop
22:47.32prpplagueflyback: hey you said you have aspergers right?
22:47.51flybacksuspected
22:48.22prpplagueflyback: do you have super sensitivety to sounds or taste ?
22:48.27flybackhahaaha
22:48.32flybackyou have no idea :)
22:48.39flybackand smell
22:48.49flybackI have to sleep with 3 fans and a hair dryer
22:48.58flybackjust to drown out all the house creaks etc
22:49.51flybackI could probably tell you which woman in the room was menstrating and I am not trying to be crude here, my sense of smell is just really sharp
22:49.51prpplagueflyback: some people with AS report having problems using paper products like tissues and paper towels
22:49.57prpplagueflyback: you have that?
22:50.06flybackin what sense?
22:50.16flybackno neither of those bug me
22:50.17prpplagueflyback: that it feels "strange"
22:50.29flybackbut I can feel dust even thru my flip-flops
22:50.31flybackon the floor
22:50.39flybackjust cause of the slickness factor of the floor etc
22:50.49prpplagueflyback: what about foods?
22:51.07flybackif I get something I don't like it's like someone wacked me in the head with a baseball bat :)
22:51.16flybackUGHHHHHHHHHHH for 20 mins :P
22:52.19flybackquick question off the subject
22:52.20flybackthis
22:52.21flybackhttp://www.spacemart.com/reports/Maxwell_Offers_Fully_SpaceQualified_HighDensity_SDRAM.html
22:52.27flybackwhat do they do, just drown the part in lead?
22:53.36flybackI recentely read that plain old polyetheylene even has amazing radiation reducing properties, I think because it's secondary emissions are less violent
22:53.51flybackyou can answer this laetr
22:53.58flybackjust wondered when you have the time
22:54.43flybackyeah my dad always noticed that I had really sharp senses
22:54.57flybackI think in the last 2 yrs I destroyed my hearing though :(
22:56.19prpplagueflyback: i was just curious, i got to thinking about it the other day, and my wife's daughter really fits with asperger's symptoms
22:56.36flybackshe really smart?
22:57.01flybacklike in some field
22:57.53flybackfeel free to bug me any time about it
22:58.02flybackalso there is a guy on freenode once in a while called cowclops
22:58.10flybackhe suspects it as well
22:58.35prpplagueflyback: in generally pretty smart, but she is obsessive about stuff, plus super sensitive to sounds, smells, taste, and touch
22:59.16flybackyeah I know that feeling
22:59.34*** join/#edev T0mW (n=Tom@24.238.68.20.res-cmts.sth.ptd.net)
22:59.49prpplagueT0mW: hey hey
23:00.16flybackprpp I guess because it's mostly hydrogen
23:00.48flybackeither polyethylene is a natural radiation whore or it's 2ndard emission particles are much weaker
23:01.20prpplagueT0mW: just realized that i can use standard pc memory with my arm projects hehe
23:01.45flybackhehehe
23:01.51flybackI could have told you that
23:02.14flybackprpplague might be able to use video ram as well
23:02.21flybackSGRAM I think it's just dual ported sdram
23:02.22prpplagueflyback: well there a wide range of sdram, just didn't know that it was that common
23:02.45flybackyou can probably just clamp off the extra i/o
23:02.46prpplagueflyback: about 30% of the boards i sampled on ebay were usable
23:02.57flyback?
23:03.02flybackyou mean for ram salvage?
23:03.15prpplagueflyback: no i mean usable with my arm projects
23:03.17flybackor arm boards that could take sdram chips
23:03.19flybackah
23:03.48flybackI seen some embedded boards that let you stack a bunch of 28xxx/29xxx series eeprom chips into one virtual disk too
23:03.49prpplaguenot all of them are low power, and not all of them have a x16 config
23:04.05flybackwhat are sdram normally x32 wide or x16?
23:04.21prpplagueyou can get them x4 x8 x16 x32
23:04.28flybackhere's a tip btw
23:04.47flybacknm
23:04.53flybackprobably not relevant
23:05.13flybackI was going to say some of the really low end 3d cards used 32 bit sdram so might be a good source of chips if you couldn't find something else
23:05.25flybackprobably much easier sources though
23:05.33prpplagueyea i can pick up some these sodim cards really cheap
23:05.40flybacktrue
23:05.45prpplaguemost of the 32 and 64 are going under $8
23:05.57flybackchips that a pc is starving on, a embedded board would be swiming it
23:05.59flybackin
23:06.14flybackhell you can probably get some for free :P
23:06.24prpplagueyea, since the pixter only has 4mb going to 32 would be great
23:06.31T0mWprpplague: sure, just wire the pins up to the signals on the SDRAM simm
23:06.52flybackhell if you couldn't use the whole memory chip and had to bank switch it somehow
23:06.59flybackit would probably still be a major boost over 4mb
23:07.06agaffneyheh, reading about asperger's, many of the symptoms fit me
23:07.09agaffneynot all, though
23:07.20prpplagueT0mW: yea, i could get a sodim connector for my project as well hehe
23:07.25flybackI have a friend I been trying to come here
23:07.34flybackhe's brilliant, he got me into this stuff
23:07.39T0mWprpplague: fastest way to get "upgrade" ram for a ARM system is to peel it off a PC SIMM
23:07.46flybackhe used to hack isa ide controllers to share interrupts so he could have 20 ide drives in 1 pc
23:07.52flybackand 8 meg of ram on a c128, etc
23:07.56flybackwild hacks
23:08.12flybackhe loves z80 cpm stuff
23:08.16flybackprobably would fit right in
23:08.57flybackhe's been having problems though :( he's suffering post tramatic stress from when he psycho wife plunged a knife in his chest many yrs ago
23:09.17flyback:/
23:09.22agaffney...
23:09.44flybackagaffney yeah not much you can say about that
23:09.45flybackit just sucks :/
23:09.55prpplagueT0mW: yea, well i've always had the ram , i was just looking for good hack supplies
23:10.12prpplagueT0mW: i decided to do my pixter stuff on seperate boards first
23:10.19flybackprpplague I just recentely learned the purpose of chip select/enable pin
23:10.21T0mWbrb
23:10.25flybackyeah I know it's all "duaH" to you guys
23:10.26*** join/#edev T0mW (n=Tom@24.238.68.20.res-cmts.sth.ptd.net)
23:10.28flybackbut that's just brilliant
23:10.29flyback:)
23:10.31flybackto me
23:10.35prpplagueT0mW: re
23:10.42prpplagueflyback: it takes time
23:10.59flybackyeah I know :/
23:11.01prpplaguei think T0mW would agree, you don't learn embedded over night
23:11.14flybackyeah I know that much :P
23:11.15T0mWprpplague: just trying to get xchat colors "right"
23:11.37prpplagueuh you said "colors" ???
23:11.52flybackprpplague woul dyou like to see that article on plastic spaceships
23:12.02prpplagueno thank you
23:12.08flybackchannel relevance being fututure cheaper shielding for electronics
23:12.08flybacknp
23:13.04prpplagueT0mW: just wish there were some nice modules for flash similiar to whats in the webpal
23:13.16flybackhehehe :)
23:13.29flybackwhat about all that disk on chip stuff
23:13.50prpplagueall propreitary
23:13.56flybackany of your arm gear have a interface for that?
23:13.57flybackoh
23:13.59flybackdamn
23:14.08prpplagueflyback: DoC was a good ideal, just poorly implemented
23:14.22flybackkinda like my folks having children
23:14.25prpplagueflyback: DoC is just a standard address data bus
23:14.34flybacknice
23:14.47flybackmy palm uses one
23:15.01flybackhopefully linux will be able to bang it around once I install it
23:15.25flybackI did read about their controller and filesystem well subfilesystem used internally
23:15.57flybackit looked good from what I understand, trying to do everything to wear all the sectors evenly and also keep performance and data integrity high
23:16.05flybackbut you guys know the lower level better than I do
23:18.31prpplaguehttp://www.micron.com/products/partdetail?part=MT8LSDT864HG-133
23:18.45prpplaguethat appears to be the most commonly use sdram sodim
23:19.07flybackprpplague yeah there were a lot of mini-itx and embedded pc boards that used so-dimms
23:19.10flybacknow that I think about it
23:19.14flybackwasn't just laptops
23:19.26flybackso you should have quit the spectrum to choose from
23:19.29flybackquite
23:19.51flybackare you going to try to use the module or just remove the chips?
23:19.57prpplagueyea, i could use 2 of the chips, which would give me 16mb, or possible add a second bank which would be 32mb
23:20.03flybackah
23:20.04flybackmmmm
23:20.30prpplaguebbiab
23:20.32flybackok :)
23:20.36flybackhave fun :)
23:21.16flybackhttp://www.micron.com/products/dram/sdram/partlist.aspx
23:21.17flybackbtw
23:21.36flybackyuo can purchase just chips or even bare die (uh no for hobbyist :P)
