@rc2014 @electron_greg back in school we had a special, modular custom-bus based #intel8085 system to teach us about computers and programming.
It also had a switch panel and I fondly remember looking up opcodes in a photocopied table so that I knew which value to "toggle" next on the switches before writing it to a memory address. Hands on computing, the real way.
It was called #MFA (microcomputer für ausbildung - microcomputer for training) and it also ran CP/M and featured a #Siemens #SPS module (god, I hate SPS).
It was this system I learned #intel8085 #assembler on.
P.S.: I guess this baby and the fond memory I have of it made me fall in love with #rc2014 decades later ...
