PC8801 3.5 Floppy

Post by Akibakun » Fri Feb 02, 2018 3:33 pm

Hello. I am a new member and I just wanted to ask some questions:

I have a PC8801MK2SR and I would like to connect a "3.5 floppy. Is it possible to connect a "3.5 by replacing one of the "5 inch floppy drives? And if possible, how can I do this? Is it possible to take a PC98 "3.5 floppy and put it into the PC88 computer, or is it not compatible?

The question is because although I eventually want to use a HxC floppy drive emulator, I first want to try this solution since I have a big bunch of "3.5 floppies in my house that would be useful.

Anyone with experience of this? Is the procedure the same as with connecting the HxC floppy emulator? Could I just take/make a cable intended for the HxC and then just put a "3.5 floppy drive there instead of the HxC?

Sorry for the noob questions. Thanks in advance.

Hi there. I have a non-SR PC8801mkII and have been looking into it myself.

Here is a page that I found on the subject: http://tulip-house.ddo.jp/DIGITAL/FD88/index.html

Here is the pinout that is provided on that page:

The gentleman in the link made a handmade adapter, but I'm not sure if I will do the same thing or just cut up a ribbon cable. I do not know enough about floppy drive connectors yet to tell if there is an easier way - perhaps something off the shelf.

I am not sure if this is the same cable as the one you would use with an HxC/Gotek but I assume so.

Good luck! Please let me know if you are successful, or even if you want to discuss general PC-88 topics/repairs. It's hard to find English-language material on these computers.
