40 years ago, programmed in assembly 680x . could read and understand 808x asm (and z80 and 6502).
Then, chose another job.
Became a satisfied hobbyist 5 years ago, with Arduino, Energia (could make a 1Ms/s oscilloscope for fun; use the latest boards I can buy) and STM32
I begin trying to play ... with 8252 (for historical reasons) and ESP32 (less wires to connect)
BTW : as I try to fill this profile , I noticed I did not nrrd trwrds, nor paypal, then.
