I wish there were kit-orderable computers of this fashion. I'd like to get my hands on something like this with a Z80 or maybe even a J11 so I can play Bell Labs in my spare time.

I have buit several z80 and 6502 kits in recent years with high school students involved with my nonprofit LoudounCodes. This one is my favorite - http://cpuville.com/Z80_kit.html

You can see a video of me talking about programming it here - https://vimeopro.com/user24051491/rubynation-2016/video/1778...

I always wanted to make my own processor out of ICs however I was informed this would be extremely slow in the end, so I never started making it. But it seemed fun at the time to make a 16-bit computer up from logic gates.

I still plan to make some FPGA's at some point. More likely, convince some CompSci people with high-end tools to build and FOSS the key components. Archipelago FPGA at 45-65nm was a start. I think even obsolete version at 28-45nm could have plenty of logic, memory, and speed for lots of hobbyist hardware.

I think saw a link on the page to order a kit, but the site seems to be having problems now.

Aren't these somewhat rare? I don't think they were used in much besides a handful of late MSX add-on video cards.

Not to mention the two (!) SIDs for audio output. The only way to obtain those nowadays is to cannibalize Commodore 64s.
