Okay, make that an Orange Pi Zero. Probably a better bang for the buck:

Not quite - the $5 Zero is single-core. You have to go to a Pi2 or

Not super-fast; 168 MHz clock, but fast enough and 5V tolerant I/Os.
And even that approach is dated today. Goo

That's the scheme I have in mind for making a Pertec interface one of these

You're right--the card, as much as I can see of it, matches a TX-8. I
was thinking of the PCTD-III 8-bit controller. Supporting an F880 with

I didn't see any 50 pin connectors, or regulators. If you
look closely it's 8-bit ISA.
