Easy to build Z80 single board computer

[Alexis] sent in a single board computer he’s been working on. The project goal of his build was making it easily reproducible. From looking at the schematics, it’s one of the simplest fully-functional computers we’ve seen. The build runs CP/M 2.2 off of two 3.5 inch floppies. This opens up a lot of options as to what software is already … Read the rest

Zilog in a matchbox

Now you can have a Zilog computer in the form factor of a matchbox. The RamBlade is a tiny PCB that uses a Parallax Propeller IC to implement the CP/M language. The OS is stored on a microSD card, with a four-pin serial interface (3V3, GND, SO, SI) that allows operation via a terminal program.

Smaller and more resilient … Read the rest

N8VEM computer with a 3Km wireless link

pterm

[James] sent in this project in which he built a tiny computer with text based OS and a 3Km wireless link. The details are a bit scarce, but he used an N8VEM, a Propeller Pocket Term, a 4 line LCD and an RF Transceiver to build it. It runs CP/M, the text based operating system and uses less than … Read the rest

N8VEM single board Z80 computer

n8vem

The N8VEM is a homebrew computer project based on the classic Z80 microprocessor. It’s designed to be easy to build using large TTL DIP components instead of SMD devices. It runs the CP/M operating system and all drives are virtual in RAM/ROM. While the base hardware is interesting, we really like the potential for expansion using a backplane. Have a … Read the rest
