Hi all, I have an ancient device that I am mapping out a schematic for. The bulk of the device is shift registers, but there are also 4 Programmable Array Logic devices. (PAL16L8ACN)
Does anyone here have any experience generating fuse-maps from existing PAL ICs? I do not have the original Fuse map, and as of yet, i have no idea how to determine the setup of these devices.
Anyone have some tips?
