Eye candy

Forgot all about these... piles of NOS z8002's still in their tubes.

As far as an update goes:
I've been working on a lot of board repairs (non PP related) to fund the finishing of my basement lab. It gets damp in the summer and pretty cold in the winter and I find it hard to get motivated (especially during Jan/Feb). A few outside chores to wrap up and then I should be able to get started an that.

10xx headway

The 10xx custom is nearly done. The system resets and passes all self tests, but the watchdog goes off right before the track appears. Which tells me it's a bus control scenario between the 10xx and the 08xx. I'm tracing the Z80 bus to see where it gets lost in the weeds and once I figure that out, should be an easy fix. Stay tuned for a complete overview on how I've helped automate the reverse engineering of the customs. It's saved me tons of time.
