Our first
programmer at work would have a view of the fusemap on the
CRT for each given PAL and you had to fill in the worksheet for that
fusemap and use that as your guide as you scroll the cursor thru the
screen to mark the appropriate fuse for your design to program. I
still can't recall who made that programmer.
That actually sounds pretty neat! Someone needs to write a fusemap
visualizer for JEDEC PAL fusemap files. Although one can usually
visualize it pretty well just by looking at the file. ;)
