This is modern clone of ZX computer based on CPLD but with original CPU, RAM/ROM and Sound chip. As a result - very small factor. I print case for this and print keyboard plate. Connection between keys was made by wires. Project finish and looks very nice. Links Github with Sizif project Photo front 3d
I couldn’t resist today and bought a Galaksija PCB. It was a home computer, in DIY format. Schematics were first published in the Yugoslavian magazine Galaksia in 1983. From architect point of view it’s has strange solution in video generation, cassette port. No video generation logic exist and CPU responsible for generation video signal, so computer was very slow. But from historic point of view its very interesting. My replica schematic is mostly close to original, but has some correction - many wires traces already on board and added rf video output. Gerbers available. ...
Overview New born PCB, recreation of the original hardware and retains all the original features and any bugs that may have existed back in the day! The only modification is the addition of ceramic capacitors for decoupling I order clear PCB, fully soldered now (it takes one evening). Case was print using this project.

Clone of original Jupiter ACE computer. This computer was a competitor to ZX81 and looks close, but from hardware reason doesnt use ULA and from software point of view use Forth instead of basic. I order clear PCB and start building by myself. Links Wikipedia article about this computer. Searle Grant site with instruction how to build jupiter. Photo clear pcb
