that would be what we'd need to knowġ8:51 the pippin had a special slot for this that i haven't seen elsewhereġ8:51 yeah, it's a weird card edge connector instead of a simm/dimm slot it looks likeĢ1:52 there are traces to contacts on both sidesĢ2:03 yeah, if most contacts have traces on both sides it's probably a dimmĢ2:03 just means it probably has to be at least 4 layersĢ2:07 in the absence of a pinout, would datasheets of the flash chips help? they're just generic intel chips, i think i have a part #Ģ2:08 8 of them per side, 262144 bytes eachĢ2:17 if you traced the flash chips out to the pins, that would helpĢ2:17 is that all that's on the board? I see a chip in the middle tooĢ2:26 blitter: how many pins are the DIMMs?Ģ2:26 these are probably the same as the PPC PerformasĢ2:26 and possibly all the way up to the Beige G3Ģ2:26 a reprogrammable ROM DIMM for those would be neat.Ģ2:28 the chip in the middle says P52AB 74F86 on it and has a tiny national semiconductor logo on itĢ2:30 does the beige g3 use a similar card in it? i have one handy, i can look and compare itĢ2:31 hmm the rom dimm on my beige g3 is longer than the pippin cardĢ2:31 there's a slot next to it labeled "sgram only" though which is closerĢ2:32 idk if the pins are similar, i don't have anything in that slotĢ2:32 how many pins is the beige g3 rom dimm?Ģ2:32 and do you have one of those crappy mid-era performas?Ģ2:35 unfortunately the only performas i have are LC040sĢ2:35 that's the one for the Pippin, right?Ģ2:40 Don't think I've seen one with Intel Flash.Ģ2:40 i wonder if amelio was still at natl semi when these were made :PĢ2:41 i'm guessing some kind of memory controller?Ģ2:41 like the MMC chips found in some NES carts maybe? idkĢ2:42 i'm a bit of a noob when it comes to thisĢ3:13 No, the STB is a different thing, '040 based.

:)ġ8:50 also, if you can see traces going to connectors on both sides of the pcb, that would probably indicate a dimmġ8:50 what i mean is a trace going to essentially each pinġ8:50 ok, i can already tell it's not a normal mac rom simm from that, so either way, would require new hardware work :)ġ8:50 i don't know anything about the pinouts. no idea of the pinout of the pippin socket eitherġ8:46 - ClassicHasClass was doing something with this on ThinkClassic, I think? or is the apple interactive television set top box something else?ġ8:48 not sure, is there a way to tell visually?ġ8:48 pippen and interactive television box are different afaikġ8:49 STB predates pippin too i think by 3 or 4 yearsġ8:49 well, one thing that would be helpful is the number of pinsġ8:49 and yes, this has come up before, and the same basic questions were asked, and nobody knew or looked into it.
is it a SIMM or a DIMM? DIMM is more complicated to do. however i don't think the 1.3 ROM has surfaced onlineġ2:42 but using this dev ROM makes me really nervous, as it's the only one i've ever come across and i'd hate for something to happen to it if i'm carelessġ7:51 blitter: iirc the dumps of one of the pippin roms the powerpc boot part in the last 1mb has a bad checksum and may or may not workġ8:45 blitter: i'm only here for a few minutes and then i have to go afk again.but i dunno.
i think only apple has/had thatġ2:40 blitter: Whoa, what's your idea with that? :)ġ2:41 bypass the authentication check so I can run whateverġ2:41 the dev ROM can do that iirc, and the 1.3 ROM can. the programmable one from appleġ2:39 no programmer for it though. Monday, Novem12:38 hey dougg3 maybe i asked this before- how hard would it be to do a pippin rom simm?ġ2:39 in the absence of schematics, i've got access to an original dev ROM.
