If anyone cares, I've been working on a Pertec tape controller design.
The initial version worked remarkably well with only a few bodge wires.
I'm assembling the respin of the design and do not anticipate any issues.
It's basically a 4x6 inch PCB with a bunch of through-hole TTL hooked to
a piggyback MCU. I've selected the STM32F407 Chinese boards as they're
inexpensive and easily available from Aliexpress, unlike a lot of the
other MCU boards which seem to have been hit by the chip shortage.
I very much care; indeed I had thoughts of maybe doing something
similar, using a BeagleBone, but this sounds a lot easier.
Would like to know exactly what board you chose, so I can acquire one.
I have a cipher drive and an HP 88780A that would be good candidates to
use with this / use this to test. I also have a DG drive that might
well have a Pertec interface (haven't looked in a while).
