I have a kennedy 9100 with an unformatted pertec

love to use for imaging tapes from my AS/400
It seems like strapping a logic analyzer to the read connector, and an
arduino on the command connector, may be fairly easily done? Has anyone
done that?
I have to confess that I've never understood the Arduino thing. It
seems to be limiting the functionality of an MCU in the name of convenience. An inexpensive STM32F4 or F7 MCU can have, depending
on the package,
over 100 5V tolerant GPIOs, lots of DMA channels, 15 timers, USB
support, and even handle ethernet.
It's just a matter of programming. F4 MCU dev boards are cheap.
Don't know that one, but I guess I should look
Maybe it's the 1000+ page reference manual that
has people spooked? Or
perhaps there's a revulsion for ARM MCUs....
Many newer Arduinos are ARM; I've used both those and the earlier ones.
For some stuff I now like to go for Raspberry Pico, which is like a more-powerful Arduino
for less money. My DDCMP controller uses one of those.
