As much as Tony doesn't like it, I need to point
out that a modern MCU
quite often has as much (or more) RAM, and runs faster than many older
PCs. Consider, for example, the lowly STM32H7A3 series. 1.4MB of RAM,
2MB of program flash, 5 DMA controllers, ethernet, TFT LCD, up to 164 5V
tolerant GPIOs, USB OTG...I won't go on.
Now wait a second. I never said that in this thread. I said that I
know nothing about them.
I am NOT, repeat NOT, contemplating wiring up a load of TTL or AM2900
bit slice chips or... to make a floppy controller or a flux transition
time recorder. I am happy to use a microcontroller. But as I know
nothing about them I am looking for a solution that 'works'. I do not
want to start having to rewrite the firmware.
Why tinker around with a PC when your MCU is more powerful? I store my
retrieved data on a 32GB SD card.
I enjoy classic computers which are simple enough for me to understand
and to get to do what _I_ want. This does not mean they're the only
thing I consider for solving a problem.
