PAL brute forcing using closed loop feedback w/ open-tl866
The following parts are currently of interest:
Part | Supported | Notes |
---|---|---|
PAL16L8 | Yes | Need to post process |
PAL16R8 | Partial | CLK related bug |
PALCE20V8H | No | Future |
PA7140T | No | Future |
Install open-tl866 bitbang firmware
Insert chip in normal socket position (notch as close to lever as possible)
Run:
python3 pal16xx.py --part PAL16L8 out.jl
This should take about 6 seconds
Now convert to "EPROM" format so it can be fed into existing post processing tools:
python3 jl2eprom.py out.jl out.bin
This should give you a 1 KB .bin file
This should give equivilent output to say something like this
TODO: this tool expects 2 KB input? Do we need to pad?
