Ms. PC-9801 if you're NS/T

I got ahold of a PC-98 laptop. Unfortunately, it has a lot of battery leakage and won’t power on. Come hang out and smell the vinegar with me for a little while.

I removed the clock battery from my X68000 ACE, sped up my PC-98’s video, and got a keyboard for my PC-8801MH. Come enjoy this bite-sized collection of what’s going on with my machines.

Mini updates 3 - PC98 A-Train III, Atari ST keyboard fix, FM-7 video adapter

Some more mini updates for things that weren’t big enough to merit a full update on their own. In this entry, we’ll finally get A-Train III running on my PC98, fix an Atari ST keyboard, and ship new hardware for a whole new brand of Japanese 8-bit computer.

I’ve been up to a bunch of little projects while waiting on parts and time for the big jobs, so here is another mini-update on three of those projects.

The PC98 can remember lots of things

Just as I was beginning to lose hope that the hard drive I had ordered back in August from Yahoo Auctions Japan would ever arrive, my doorbell rang. Inside a beat-up but functional Suruga-ya box sat the hard drive, done with its international journey.

Exploring the PC98 software catalogue

Now that the PC98 can load software off of a USB stick instead of floppies, I decided to explore the software catalogue a bit.

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-9821AP2/U8W - day two

I only had a short amount of time to play with the computer today, but thanks to a very knowledgable friend, I got a known-good DOS 6.2 image with some disk utilities written to a floppy and booted.

PC-9821AP2/U8W - day one

Months ago, I won a PC-8801mkII and a PC-9821AP2/U8W off Yahoo Auctions. They arrived, but life got busy, and so the blog hasn’t been updated in quite some time. What better way to bring it back than a deep-dive into a computer whose language I literally do not speak or understand in even the slightest way?
