This is a recreation of the ZX Max 128 Issue 5 PCB as designed by DonSuperfo but done in KiCAD 10.
This was only done in order to create an interactive BOM (in the BOM folder) to assist in the assembling of the PCB.
The KiCAD schematics 'should' be correct but nothing should be assumed as correct without checking with the original schematic and PCB layout. Although I have followed the original track and via layout further checking should be done before using these files to order a pcb with. Currently I would still order the pcb from PCBWay using the link from https://github.com/DonSuperfo/ZX-Max-128
Note that any part number for any device used in this project might not be the correct one from the original BOM as supplied from PCBWay as I had to change some parts to get a footprint that would fit in the space on the original pcb with the correct pin spacing. This required selecting a different part number or vendor. This applies mainly to capacitors. Some other parts are no longer available under that number from Digikey.
As always, measure twice and order one.
Use at your own risk.
