Gotek with HxC won't work in PC-8801FA/MA.

Post by fyk »

Hi there,

Gotek with HxC firmware won't work in PC-8801FA and PC-8801MA.
firmware version is HxCFEUSB_V4_2_10_12a.

When two Goteks(DS0/DS1) are connected on one FD cable, Games requiring 2 FD are not working.
I use the modified FD cable. The modification is pin#10 of Drive#2 is connected to pin#12 of Drive1.

When HxC(DS0/DS1) is connected on the one FD cable which is the same cable for Gotek, Games requiring 2 FD are working.

When one Gotek(DS0) is connected on one FD cable, Games requiring 1 FD are working.

It happens the same issue on PC-8801FA + two Goteks with FF firmware(v3.3).
However, PC-8801FA + two Goteks with FF firmware(v1.2) works well.

Do you have any guess why it won't work?

How have you connected the emulators ?
Some PC88 machines have 2 different floppy connectors on the motherboard. Each connector have a different drive select signal. i think that both drives should be set as DS0 (to be checked...).

Thank for your reply.
I checked my Goteks and FD cables.
I changed another FD cable, Gotek worked.

However, Gotek with that Cable which was not good for PC-8801 worked on Sharp X1 and Fujitsu FM77AV.
I also changed from two Gotek to one HxC with that Cable, it worked on PC-8801. I don't know why that Gotek with that cable did not work on PC-8801....)

Anyway, Thanks again.

Was one cable twisted and the other not?

Two Goteks are connected to one FD cable. And I used a modified the FD cable as below.
- pin#10 of Drive#2 signals from M/B is connected to pin#12 of FD cable of Drive#1.
