Unbelievable. Uses 4 chips, each one 4-bit and containing 75 logic gates giving the programmer 32 instructions (almost half that of the dreadful BBC Micro!) - 16 arithmetic and 16 logic. Originally ran at 45 Mhz, later models at 90 Mhz and 143 Mhz. We were subsequently sold criples of computers. What dupes we were. 🦕

I assume there were no printers available to cut the rubylith afterwards? Were the completed designs then drawn out and cut by hand?
I love to get a hold of that Alto keyboard.
