Be gentle with me chaps, PAL's are a new area for me so please forgive stupid questions and don't make any assumptions in your answers...
I'm hoping to 're-manufacture' a circuit board I have - nothing cleaver:
-Look up codes of IC's etc, buy said components
-Study PCB layout, reproduce PCB using transfer technique
-Solder it all up
-Fingers crossed
Now one one of these IC's is an AIMEL AT27C256R. Ok, it's an EPROM - it's about time I bought a ROM-blower.
I can retrieve the contents of the ROM via the host-computer.
But two of them are PALCE 16V8H-25's.
Hmm, PAL's eh?
I think I'm about to come unstuck...
Questions:
-What does one need to program one of these babies?
Some kind of ROM-blower?
or
Are they 'programmed' on the fly from the ROM on power-up?
If the latter that's good, no problem.
If the former - fingers crossed, I have a feeling I'm not going to like the answer...
How does one program one of these?
and
Is there any way to get the 'software' out of the PAL so it may be used to program another?
There's a minimal chance of being able to track down the original files if I can't do this - game over.
Thank you!
