Ive been dealing with a couple of System 18 boards recently.
Ive dumped two PLS153 chips and a PAL16L8.
PLS153’s cant be security locked to my knowledge and can SOMETIMES be converted to a GAL16V8.
caius sent me some dumps from his LCR board.
One of the devices was an EP330 which we have converted to GAL16V8. Both the unprotected original and the GAL conversion are available.
The other device was a protected but has been dumped using a PAL dumper.
Thanks to caius
Dieter sent me a couple of dumps and a test MAME dump
The 2 he dumped are from bootleg boards Tiger Heli and Mr. Do. The PAL was unprotected. He has also sent the GAL16V8 conversion which are tested. Both have been added
He also sent in the Xevios PAL dump from the MAME set and the GAL16V8 conversion is also included.
Thanks Dieter
Been going through a few more scrap boards and found one on a dead Final Round PCB (GX870) marked 007793.
I originally dumped this using the PAL dumper but then found the original to be unlocked so both have been added.
This has been marked as assumed working due to the original chip being unlocked and my recreated equations match the original dump
Ive got a non working Turbo Force PCB that has 5 EPL16P8 devices on it. Here im assuming they are compatible with PAL16L8 devices and used the PAL dumper hardware to clone them.
They are untested but hopefully they work and someone can test them out.
