About the Z80-breakout
Z80-breakout is an open source PCB design by lkesteloot, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 22.9 × 53.3 mm, with 3 components from 2 distinct parts.
Other key parts include the Z80CPU-SMD. By type, the board carries 2 connectors and 1 IC.
It belongs with the retro computing and dev boards & breakouts designs in this gallery.
From the project
Website documenting a hardware project from the 1990s.
This is the third model of the Alice machine. It runs a silicon Z80 with two co-processors: an ARM for keyboard, disk, and serial port, and a Propeller for video.
The 80MHz Propeller has 48K of internal RAM, drives VGA and the 5-pin Aux connector (intended for audio but wired generically to 3 Propeller pins) and thus provides opportunities for video and other experimentation.
