That looks like it could be reverse engineered from the image alone...

Then you may find the Apple original schematic helpful, too :)

Hmm - have you got the IIci schematics to work with, first of all? :)

The famed IKEA Lack Rack!

Most DRAM in the same packaging are the same type of DRAM - JEDEC defined pinouts at least. Very few, if any RAM manufacturers choose to ignore the JEDEC standards.

I have a brick of PowerPC 601's from IBM with apple part numbers on the label, probably the same issue - never used!

Here are some - pricey though: https://www.ebay.co.uk/itm/264261264395 These are a bargain for 3 pieces: https://shop.tvsat.com.pl/en_GB/p/3pcs-TC524256Z-10-1MBit-CMOS-Multiport-DRAM-ZIP28-TOSHIBA/21158 Looks like almost all 1mbit ZIP28 RAM is 256k x 4-bit multi port DRAM. OKI MSM514262...

Hi Peter, I'm sorry I have no boards left, I gave up stocking them a while ago and deferred to Maceffects in the US as that's where 90% of the interest was for them (as you know not many macs in Europe by comparison). The latest version adds an extra pin header for an additional address line...

Correct any rack mount kit can run pretty much wherever you want. Right now I'm running a Dell R520 on its side, stuffed under the desk, penned in by two desktop pc cases and a mac pro 🤣

Pinouts for most ASIC's used in the SE/30 are here: https://docs.google.com/spreadsheets/d/1NDIA5orTwraRmOUgzrKxWYXcf2AXdULkdwUm020HdXI/edit#gid=0

The board has already made it's position clear in an official capacity, so i'm taking my board president hat off here - I have absolutely NO issue with anyone sharing their experiences with anyone, literally none. As @Yoda points out above, TD has ZERO finances to fight any kind of legal case...

I wonder if someone (*cough* @alxlab *cough*) would try and make a similar "socket blaster" to use the low voltage 040's in regular machines, as has been done for 486 machines

Have you got a part number of the original ZIP chips that I can use to find a cross reference? :)

I can think of a few, but none suitable for polite company!

Post in this thread! :)

Moving from the Lab's software section to compact macs, as this is nothing to do with software. Please can you be mindful of the categories your threads are being posted in.

There's one more that could be made - a PLCC 44 pinout to PLCC-28 through hole socket layout - for Mac II's that shipped with an IWM, cause there was a PLCC-28 SWIM available for them in an upgrade kit that was used almost no one else.

Personal opinion - this is something I absolutely agree with, but i'll raise it as an agenda item for the next board meeting.

I believe you're using the XC and MC nomenclature incorrectly. MC just means a qualified part. XC means 'in development'. It does not refer to an FPU or not. In 68040 land, 68040 means fully enabled part, 68LC040 means no FPU, 68EC040 means no MMU or FPU. In the 68030, there was no such...

I wonder if a IIcx reloaded from @max1zzz might be the best place to start with now that you've gone through the exhaustive process of recapping and rewiring everything.
