Sounds like a cool course, was Z80 in my day, and I am not *that* old
2K ram dev board to play with, nothing but a numeric screen and basic keyboard to enter machine code into ram and run it. was great stuff. Probably forgot most of it!
Always remember a task to count from 0000 to 1111 on a LED 8 bit output port.easy stuff.. kinda.. Then the tutor said now we have to get it to count on the upper 4 bits of the port, not the lower 4 bits... needless to say everyone over thought it and basically couldn't do it! I think one of my programs I actually ran out of ram!
Tutor gave us a hint that we only needed 1 command to do it... "AH...oops"
