    Reproducing the Lisa 2 Card Stack: The CPU Card

    That is amazing to hear, now the race is on to see who will be the first person to make a completely brand new Lisa in almost 40 years!

    That is amazing news!! Really hoping that error logic issue is something simple - at least it's not getting in the way of booting LOS. Now all that's left is to test the ram card and you've got a complete stack Lisa stack!

The COP would be neat to reverse engineer, but I think there are enough ROMless version of the COP (and the soviet clones!) It's not a...

    Wow. Just... Wow! That is more or less exactly the same objectives I was planning to complete. You even cloned the SunRem 2mb RAM card!! Even the idea of replacing the power supply with an ATX PSU - I guess great minds do think alike! I suppose in a way that my end goal is marginally...
