Just to let you know, I'm willing to purchase any additional test board / test module you develop in the future.
IMHO there will be enough collectors interested in the test boards for the following CPU families:6502
680x
68000
1802
2650
TMS9900
8086/8088
8087

650x/680x could be one board, the more one board supports the better, less work for molka lol
8086/8088 could of course be one too
Not sure what others could be combined.

I'd like to add the
F8 (3850)
PPS-4
TMS 1000
... haha, a lot of work, hm, bit slices, 2901, ...

Very nice wish lists lol.
I'll pick some of them.
I started thinking the design of 650x/680x tester.
But the next one will be a 1802 tester. It's architecture is really interesting to me. I did not know it earlier. Thanks to isa-d, who suggested it.

Although I'd certainly purchase any tester you come up with, Lee Hart's membership card makes an easy and inexpensive tester for the 1802 as well as being a fun little project.
I'd vote for a 6800 based project, even better if it supported MkBug.
Some of the recent 6502 variants like the Western Digital W65C02S6TPG-14 have some subtle pinout differences from the original MOS parts. I found that out the hard way.

One really interesting project (at least for me) would be to re-produce a version of the SC/MP INS8060. It was an early single board computer and a version of basic is available. |

Pretty much what the INS8073 was, a 3rd gen SC/MP with BASIC built in

You are right, Lee Hart's membership card is a great project. But as far as I know that is sold as a kit. And not everyone can solder it easily. On the other hand changing the CPU in it is not as simple then putting one into a ZIF socket. And you have to enter the test code in it because it contains only RAM memory.
That's why I'd like to implement a very simple 1802 test board with the same functionality as my MCS-80 tester. (with 1802, 1805, 1806 test capabilities)

I got the PCBs and I made the NSC800 expansions. They work fine.
They cost $12.00 each. I can ship them on next week.

One for me please, perhaps to combine shipping with the 180x tester?
