Re: Found a ROM SIMM....
From: John Niven [EMAIL PROTECTED] Date: Thu, 7 Jul 2005 13:43:12 -0700 In my local computer junkyard I found this SIMM in an antistatic bag, so I have no idea where it comes from. It's a 64 pin simm with a notch in the middle. It has four, socketed, EPROM's which have stickers on the top. These read: 342-073* C APPLE 1983-89 W8929 where the * is 3, 4, 5, or 6 for each EPROM. Yep, definitely a IIci ROM. I checked the part numbers on the chips for one of my IIci's and they're the same. This is the most reliable way of visually identifying Apple ROMs. Each chip will have a 342- or 343- part number on it. This is also the best way to visually identify Beige G3 ROMs. OWC had a web page with a bunch of stuff about the different circuit cards, but all one needs to do is read the part number off of the chips to know which version is in hand. There are a few ROMs out there built from EEPROM chips which may just have chip manufacturer numbers on them and no Apple part numbers. I've been told that these were development ROM modules which could be reprogrammed either in the host machine or on a machine on the bench.

Found a ROM SIMM....
In my local computer junkyard I found this SIMM in an antistatic bag, so I have no idea where it comes from. It's a 64 pin simm with a notch in the middle. It has four, socketed, EPROM's which have stickers on the top. These read: 342-073* C APPLE 1983-89 W8929 where the * is 3, 4, 5, or 6 for each EPROM. Clearly W8929 means week 29 of 1989. On the web I found a reference to these ROM numbers that indicate they belong to a Mac IIci. The PCB is marked 1MEG ROM SIMM AP1257-01 Anybody any suggestions what could be done with this SIMM?

Put them in an SE/30 and see what they do. Or send them to me and I'll do it. :) johnsn In my local computer junkyard I found this SIMM in an antistatic bag, so I have no idea where it comes from.

My IIci would be willing to see what they do. :) Steve On 7/7/05, Snook, John R [EMAIL PROTECTED] wrote: Put them in an SE/30 and see what they do.
