My next CPU tester project is a CDP180x (1802, 1805, 1806) tester.
It is as simple as possible it can be, but it is expandable for future projects.
The schematics is ready, the circuit works on wire-test-board.

My small set of 1802s all work. 1805 and 1806 are not tested because I haven't got any yet. Sad

I'm working on the PCB design, but advices are welcome until it's not finished.

Less than two months after the wire model the PCB is ready for the 180x tester.

The prototype is done and works fine. Very Happy
I tested 1802, 1805 and 1806 CPUs.

If someone want to buy, I have 5 PCBs available for the first serial. It costs $38.00.

That was the 5pcs of the first serial. lol

I'll order PCBs and components for a next serial if required.
