Maybe I don't go to a decent school <wink> but we had custom m68k
boards. They weren't apples and they weren't amigas. They were
hooked up to win9x boxes through the serial port and we used hyper
terminal to send the cross-assembled code to the board. They had a
"tutor" prompt which was some sort of program that handled the
transfer of code to the board and also debugging stuff like stepping
through instructions and displaying the register contents. BTW, most
of those boards died before the end of the quarter. On a few
occaisions I saw the PC (that's "program counter", not "personal
computer") skip a byte or two which would result in a address trap.
