It executed it's first program. Had a wiring error but it can be fixed with
jumpers.

The silver lever is a Aries zero insertion force socket for getting the chip
in and
out quickly for programming purposes. There is no on board in circuit
programming
for this version. You must have a stand alone programmer.

It is not fully populated yet but all the other circuits have been tested on
the bench.

I am thinking of going one step up on processors to the 80C51.
It is at least four times faster than the 8051. It has built in USB and PWM mode for the timers.

BTW I am up in Monterey for the rotary races. Mazda owns the race track. We flew in to San Francisco which was a big mistake, You have to take a train to get a rental car. The people up here are logic and reason challenged. They could have built a big parking garage for the rental cars cheaper than the train. Total travel time was six hours. I could have driven it in 4 and the cost would be much much cheaper if you need to pay for airline tickets even with gas at $4 in CA. We don't as Robin is a retired UAL A&P.   The Comfort Inn has lousy Internet service. I am at Denny's.
