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.

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!

PC-8801mkII monochrome video works

In the last entry, we left our intrepid hero with no video out. After a quick consultation of the Japanese internet, and a not-so-quick cable soldering job later, we now have black and white video and can use N88 BASIC (at least in theory).

The PC8801mkII gets inspected

While the PC9821 has horsepower and 90s clone styling for days, the real reason I spent all this effort and money was to get personal with the PC8801 platform. This humble little NEC home computer platform launched an indie game development revolution - well, or at least it did after this one was made. In fact, this 8801mkII, having been released immediately before the gaming-friendly 8801mkIISR, is only really useful to someone super weird who wants to learn about its guts on the cheap. I don’t know anyone like that around here, so I might as well do it. You’re welcome, future historians.

The C64 is alive!

A power supply arrived from Ray Carlsen, and it works great. I spent the time while I was waiting by soldering a really bad video cable. I only managed to melt one DIN plug in the process!
