PLEASE NOTE: I do not sell production boards. If you would like to buy an M62 Z80 system board/parts kit, contact Peter Murray, Peter@39k.ca

I simply provide you with information to build your own breadboard computer.

Overview

The backplane is a simple design. It uses a 2.5mm barrel connector/power jack to:

 - power the 12v regulator which...

 - powers the 5v regulator for VCC which...

 - powers the 3.3v regulator

5vDC is used across the board. 12v and 3v3 are available via jumpers but are not used on the backplane.

How big is the ZB64PC-bus powered backplane board?

It's four inches by six inches, or 100mm x 160mm if you're metrically inclined

How many cards can I put in the backplane?

The single board computer ZB64PC-bus SBC and 5 other boards.

How do I power my backplane?

There's a 2.5mm barrel connector that needs a wall mount power supply, commonly known as a wall wart. 14vDC center positive and one Amp should easily handle the 12vDC voltage regulator.

I see the schematics. Where is the Bill of Materials parts list?

The BOM is at the bottom of the adjacent panel.

What will the backplane printed circuit board look like?
