About the Galspanic PCB
Galspanic is an open source PCB design by stas2k, published on GitHub under the MIT license. It is a 2-layer board measuring 50 × 150 mm, with 19 components from 6 distinct parts.
Other key parts include the CY62167E and ATF22V10C-10XU. By type, the board carries 7 capacitors, 6 ICs, 5 jumpers and 1 connector.
It belongs with the retro computing designs in this gallery.
From the project
X68000 RAM Expansion
This repo contains Kicad sources for a Static RAM expansion board for Sharp X68000 personal computer. Please use latest git version of kicad to open the project, or version >6.0 once it gets released.
Board dimensions are taken from the midiori project.
The board can support up to 10MB of memory and assumes you already have 2MB built in.
A fourth address line is routed and the board can support 1MB systems by masking half of the first memory chip. However, the GAL equations are not written for this case. Let me know if you have such a system.
