Some interesting vintage computer's FPGA reimplementation

Postby DrOG » Tue Apr 17, 2018 9:00 pm

Hi!

I had a lot of time for Googling and found some interesting vintage computer's FPGA reimplementation:

Compukit UK101
https://github.com/emard/UK101onFPGA
https://en.wikipedia.org/wiki/Compukit_UK101
It's a kit clone of the Ohio Scientific Superboard II single-board computer, with a few enhancements for the UK market.

Similar computers:
Galeb (Seagull) & Orao (Eagle) from ex-Yugoslavia:

UT-88
http://www.electronicsfun.net/downloads
https://en.wikipedia.org/wiki/UT-88
A DIY educational computer designed in Soviet Union.

CoBra:
https://github.com/JacekGreniger/cobra-fpga
https://ro.wikipedia.org/wiki/CoBra
A Romanian computer from Brasov.

I don't know how mature these projects are, and if they are complete or not.
Unfortunately I'm not familiar with the original systems as well to judge if it worths to port them or not.

Hi!

Yes, this core seems to be incomplete. The startup screens is full of @-s, but at least the video output is 640x480@60Hz.

The other two cores look more mature, the UT-88 can load .wav files, I'm not sure if this can be implemented or not... (perhaps similar way as Sorgelig's ZX Spectrum or your Didaktik cores do CSW loading).
