Well, I know it was done in wirewrapped logic chips first (a rats nest), and then that circuit schematic was turned into verilog and sent to vlsi for manufacturing. Although iirc Bruce told me they were using someone else first (or vlsi changed their process mid way), and they had to convert the language for the chip. Took him a while but eventually he had an "Aha!" moment and realized that if he just negated the logic, it'd work on the new system.
That's very hazy, and today sounds wrong to me, so I'm sure I'm misremembering/forgetting details.
