Hi

I was digging though some old files looking for a photo and found some mostly complete projects from a few years ago. One is a project called PD32 (Public Domain 32) which is an ISA board based on the NS32016 CPU and chipset which claims to be Unix capable. There was a magazine article in 1986 in Micro Cornucopia which laid out the plans in great detail which I used to create a refreshed duplicate. It is a full sized 8 bit ISA board.

As you can see in the 3D rendering below, it has aged somewhat and needs an update in KiCAD but it is practically complete. All it really needs is someone to adopt it and make it their own project

In addition, I have a less complete project called PD32+ which was done by a NS designer (?) basically a 16 bit refresh of the PD32 but based on the NS32032 which is a full blown 32 bit CPU inside and out. I know a lot less about this project other than it looks awesome. No PCB for it but the schematic looks fairly complete.
