2MB Card Apple Lisa + Accelerator Clones(?)
Posted by: Zhinü on 2026-06-15 15:20:45
Recently picked up a PFG for my Lisa, going through GitHub and noticed the 2MB Card Project by Warmech. I’m curious on if there’s been any updates since initial release, and how hard is it to build one (since my Lisa currently has 2 512k cards).

Also, while scrolling through LisaList, I saw mentions of a clone for the XLerator being worked on? Is that still happening or did legal issues get in the way?

XLerator clones would be so cool to build. WANT!!=)

Me too bud, me too.
I checked in with the market research post on LisaList2, and got hit with the ominous “we hit some complications that may or may not be resolved eventually,” aka they probably got C&D’d or something over the files.

I don't think so; sigma7 is an original designer of the XLerator if I'm not mistaken. So what he would provide would be a genuine device and not a clone.

XLerators have never been for me as they currently only support MacWorks; the Lisa Office System and other native OSs will not run, and for me that is where a lot of the Lisa's unique appeal lies. (If I want a fast B&W Mac, there are easier ways to get it.) But to each their own.

I believe sigma7 has mused about an XLerator variant that would incorporate a Lisa-like MMU and thereby run the old OSs, but I don't think that conversation went much further than the "betcha probably could" phase. And these days there's now the Lisa-on-an-FPGA project to scratch that "fast Lisa hardware" itch.

fpga board is not to be fitted inside a Lisa case, right?
Would be Sweet just take out the tray slide in the new boards and heaven fast Lisa

My ultimate plan is to design a second version of the LisaFPGA board that does just slide on into the back of a Lisa case, but that may be a few months off in the future. I need to get this first version out the door first!

Also, I have indeed reverse-engineered the XLerator and have talked briefly with sigma7 about releasing my cloned design publicly, but his license terms weren't quite what I wanted. For instance, I still wouldn't be allowed to release my cloned design as open-source; I'd only be able to sell people completed hardware and pay him a royalty for each one. That's why the market research thread kind of died off.

You're great. That is very nice to read.
A shame about the XLerator, but after all it only works with MacWorks XL, right? Then we might just grab a SE/30, IIfx or Quadra to play with. For me i's about the sweet multitasking in LOS i guess
