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

How many cards can I put in the backplane?

The M62-bus SBC2 (single board computer 2) 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 12v voltage regulator that feeds the other two regulators in series.

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

The BOM is at the bottom of the adjacent panel.

How big is the BP and what will the printed circuit board look like?

The Powered Multi-slot Backplane PCB measures 100mm x 160mm (4" x 6"). Click the adjacent thumbnail to see a possible parts layout.
