Using 1 HxC for 2 floppy drives on a NEC PC-8801

Post by Namida88 » Sat Oct 30, 2010 4:29 am

Here is a simple way (even if you don't have any skill in electronic) to connect just one HxC to emulate two drives on a PC-88 (thank you Jeff for your help on this !)

This was done on a PC-8801MC, but it should work on any NEC PC (I will test later with a PC-9801RA or VM).

1. Connect the HxC to the first drive connector of the mother board.
2. Set jumper as if just one drive was emulated (Drive A, ID0 with a straight cable or Drive B, ID3 with a cross cable).
3. Now connect PIN number 10 of the second drive connector to a Drive B jumper PIN of the HxC (can be any of the 4 available PIN).

If you're not sure or it's unclear, please look at these pictures (done with a cross cable):

I hope this can help it you purchased only 1 HxC.
Although I recommend using 2 HxC if the games you play require you to often swap disks.

If someone could port this on PC88 this can be interesting :
