I haven't thought of this in years. Sr Engineer wanted me to build a 'chamber simulator'. IE simulates a pressure chamber with a bunch of valves and interlocks.
Wanted me to implement it with analog circuits and jungle logic.
I went fuck that and hand built a board with an 8051. Wrote the program in assembly on paper. Hand translated it to hex. And then used a hex editor to generate the hex file. Which I used to burn the epprom. Took two days to debug it.
