    Hello,

    I have the same hack on my amiga 4000 but there seems to be a lot of incompatibility, CF card doesn’t work wit CD-rom as a Slave or the opposite.

    Is there anything to do to solve?

    I’m trying to program ATF16V8B-10JU GAL’s with the Mini Pro TL866II Plus without success.

    what programmer has been used to program the GAL 16V8 PLCC chips ?

    and what GAL chip was used (Latice or ATMEL) ?

    @Joao Martins

    GAL buyed from Cosmos (ebay) some years ago.
