The computer boom paralleled the radio boom in many
ways. One could buy
radio components from a radio parts supplier, setup on the kitchen table
and build several dozen or more radios to sell at the local hardware stores
or automobile supply stores. Most of those small companies died. Sounds
like many computer companies in the 70's and 80's and even PC companies in
recent times.
Yes, it is interesting to see how early clone BIOS chips were bootlegged
just like the 201 triodes...
