My first "micro-computer" was one I built myself (a friend's
design) based on the SC/MP ("SCAMP") (remember them?) from
NatSemi. We had 8 switches on the data bus and used the fact
that the chip would count up through memory on startup, and
had a static clock. You would start it up, set the data
switches to the required code and press "enter". This would
input one byte (here byte = 8 bits :-)) and so on. There was
NO other program loading device so you did this every time
you wanted a program loaded. I guess programs were fairly
small and power tended to be left on.

You can probably work out approximately how old I am from
this :-).
