Tetris on the Sol-20

A project log for Sol-20 Reproduction

I am making a full sized Sol-20 reproduction, the first fully assembled microcomputer with a built-in keyboard and television output.

Nino Porcino has written (in 2021!) a Tetris game in C, using the z88 C compiler. In fact, he has ported it to multiple 8-bit computer platforms. The source code is available on his github repo. This is so cool running new software on a 45 year old machine.  Tetris runs fine on my Sol-20 emulator. Lots of fun.

Happy you liked it! To make the cassette audio file of the program, I had to reverse engineer the 600 baud tape format and then make my own wav file creation utility (to be released soon).
