Dual Goteks in the PC-8801mkIISR at last

In my previous entry, I found out that my old IBM PC “DOS” floppy adapter was not sufficient when trying to read from two drives at once. Somehow, they confused the floppy controller enough that nothing could be read from the second drive.

Attempting dual Goteks in the PC-8801mkIISR

I got another couple of Gotek floppy emulators from China, and now the SR has dual floppy drives. Unfortunately, I can’t use them both at the same time.

A mystical journey to PC8801mkII colour video

I’ve been using the monochrome video cable on my PC88 ever since I built it. Colour video was a little more complicated, so I ended up designing a bunch of adapters to try and get it to work. I’m happy to announce that one of those adapters has finally worked!

PC98 - New floppy board, sound 'fixed,' more testing

Now that the PC98 can load a game off a flash drive, there’s a lot more parts of it I can test. Today, I spent a few minutes putting together a new revision of the floppy board and inspecting the computer.

Floppy adapter board works for the PC98!

After I designed the first version of my PC88 floppy board, I thought it would be fun to put one together for the PC98 as well. Why do I need an adapter for a computer that already has 3.5” floppy drives? The PC9821AP2 I own has a 26-pin floppy drive connector, like a mid-90s laptop, and most standard IBM PC style floppy drives have 34.

PC-8801mkII floppy adapter board

I wanted to get a Gotek working on my PC88, and after seeing that there were a lot of Japanese hobbyists who had managed to get an HxC floppy emulator working, decided it must be possible - even if not simple.
