I can't set the single angled simm slots that the original rocket uses, I can get doubles but these have a different row spacing and obviously they won't work for the wired 3 + 5 slot layout radius used so I need to quite a bit of moving around in the RAM section to make it all fit. Ultimately I...

I have seen a few racks that looked not much better than that!

Of course! If you want to get your own PCB's made the gerbers, PNP data and schematics are on my github (https://github.com/max234252/Macintosh-IIci-Reloaded) or if you want a single board I still have some available in purple with ENIG surface finish and with the bottom side passives all populated

As far as I am aware the original GAL and the Stage 1 ASIC rockets are the same though this is the first rocket I have actually had my hands on so I'm not 100% on that

Well I needed a breaak from the LC accelerator below :) (Which every time I think it is stable I find one LC it crashes in) So far it's been going fairly quickly, the PCB is actually clear enough I have been manageing to trace the inner layers without any real issue :)

I don't have one, but if someone has one to lend me I can have a look at it :)

Indeed it is :)

Ohh, That is something I need yo post on github - it's a pldSHWIM which is a implementation of DosFox's SCHWIM in a single 16V8 PLD, It sits on the bus and shouts "I'm a IWM" at the appropriate time to get a system through the power on diagnostics with no IWM / SWIM fitted

Close :) it a accelerator (with cache) + ethernet

Check the SN against it's original config and refuse to activate if it mismatches? Modern apple would do that. I work in the repair industry and am very bitter towards apple because that's just the kind of stuff they pull.

You can always use "modern" server drives with the appropriate adapter, being newer they should be more reliable but then even "modern" server drives will be the best part of 20 years old now.... Other option if you just want clicky sounds is i'm pretty sure both BlueSCSI and ZuluSCSI have...

Sure, sounds like fun :)

I hadn't thought that far ahead! I guess a pico PSU is probably the obvious option as it supports soft power. For my purpose loosing reset control is not a major issue, I'm looking to build a rackmac but don't want to leave it running 24/7

Any chance of hacking in a remote power on? If so I'll start yelling "Just take my money" now
