Fresh hacks every day
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
[Donn] wanted know exactly what is going on inside of a processor so naturally he built a CPU out of TTL components. He had previously built a couple of versions of a computer based on the Z80 processor. Using the troubleshooting skills he learned and a second-hand textbook, he set to work using 74LS series chips connected using … Read the rest
We’ve seen Z80 processor based computers before but they usually use a printed circuit board to easily and reliably connect all the components. [Marton] sent us his Z80 based computer from a while back that is built entirely on prototyping board. He made his own video board that utilizes a TV as the monitor and his own mainboard incorporating a … Read the rest
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
