Hi, anybody here who own this MB?
Abit AB-FU3 386 ISA - http://theretroweb.com/motherboards/s/abit-ab-fu3
I need JEDEC dump of prog. logic U6 PAL16L8.
I found that mine has completly damaged (floating) output pins 12-19 and I cannod dump it in programmer.
Due to this the MB fails with FPU when any program tries to use it. Probably because BUSY# signal is not routed from FPU to CPU. I wonder the MB boots without the chip. Maybe some similar MB could be also used, should be based on Chips F82C351/355/356 chipset...

At least I tried to reverse-engineer the PAL16L8 pin mapping:

1 - FPU K1 - PEREQ
2 - FPU K2 - BUSY#
3 - FPU L2 - ERROR#
4 - CPU E14 - ADS#
5 - F82C356 77 - NMI
6 - FPU L10 - RESETIN
7 - CPU C9 - RESET
8 - F82C351 149 - REFRESH#
9 - WTL3167 M12 - INTR
10 - GND
11 - WTL3167 M2 - PRES#
12 - CPU - BUSY#
13 - probably NC
14 - probably NC
15 - probably NC
16 - CPU A8 - ERROR#
17 - probably NC
18 - F82C356 138 - IRQ13
19 - CPU C8 - PEREQ
20 - VCC

pins 12-19 are dead, chip doesn't excessive heat or any signs of damage. It looks to me like broken bonding wires from silicon inside?
