We used to build them computers in the kitchen on wekends, nobody could afford to buy one ready made, we draw our circuit board with nail polish, sink it in battery acid to get the motherboards and the rest, drilled the holes with dremel like tools, soldered resistor by resistor, processors were Z8080, super duper, capacitors were a headache to find, bobins.... we made them by hand gauging wires with the caliper, extracted from cables, coiling them around mateal rods of the exact diameter, and counting carefully the number of turns, than measuring them with the Ohm Meter before cutting their end to make sure it mathched the desiresd frequency.
Nobody sold keyboards, we made them from a circuit board, and some keys we made out of wood blocks on springs we recuperated from pens.
There was no hard drive, nor monitors, we hooked them up to our TV and loaded programs from a casette player. And saved on casette players too by recording the session on the tape.
