Progress on the 6502 computer – Milling PCB’s

While work and other commitments have been sapping a large amount of my time I have been making slow progress with the milling of circuit boards for the 6502 computer project. I have added some pictures of progress below. I am slowly getting the hang of repeatable and reliable results on the mill. Most trouble stems from the height at...

Milled PCB Test

A few pictures of a test run trying out isolation PCB routing. GCode was generated using the PCB-Gcode script for Eagle, using the backplane board from my 6502 project as input. Part way through the run I noticed that the mill was slightly out of alignment on the X-axis, this was causing shallow track cuts which got progressively worse the further...

Using the toner transfer method has worked very well for me in the past, but it looks like my current printer doesn’t work as well as the one I used previously. Below are a few pictures of the backplane boards I tried etching, the first photo based off a...

This was strange mainly due to the fact I wasn’t yet born when the Steve’s (Wozniak and Jobs) were designing and building the Apple I & II… Some time after that I read on Hack-a-Day...
