Retrochallenge wrap-up

For this Retrochallenge, I got two different 8008 CPU board PCBs designed and fabricated, and got one fully assembled, working, and running small 8008 test programs. The second board is not yet fully assembled, but I am about to start testing it.

Here’s a photo of the second board, with only the CPLD and surface mount capacitors soldered down by my friend John D:


There are other photos of both boards in the same album.

The next step for the second board will be to install the bus connector, 3.3V regulator and capacitors, and 20 MHz oscillator, and start testing the CPLD, verifying that all the I/Os I use work properly.
