Well, definitely is not programmed, because I did not know that it needed to... And also don't know how to.
Any instructions around?

OK, I found out that the TL866+ I have can program GAL (in particular the 22V10D). And using minipro on Linux, I can detect it:
Code: Select all
Name: GAL22V10D
Memory: 5892 Bits
Package: DIP24
ICSP: -
Protocol: 0x2c
Read buffer size: 0 Bytes
Write buffer size: 0 Bytes

VPP programming voltage: 16V
Are the pins in JP22 different in the H4 board than the H5? Because in the label of the H5 B1 board, it says pins 2&3 are for "8MHz 1772" and 1&2 are for "8MHz & 16 MHz GAL mode". So, it seems to be opposite of what's described in the post, right?JP22 has pins 2 and 3 connected so that the 1.44mb IC controls the clock speed to the WD1772.
I just measured RN1, RN2, RN15, RN16 and RN17 in the H5 B1, and they are 1 kOhm.
Oh!
