Hey there;
If you are stilll playing with FMTowns, x68000 or PC98 computers, join the facebook groups x68000 club, pc98 club or FMTowns club. I really hate facebook but these groups are the only places where you can get quick help and answers from a "large" community. Unfortunately the most people in forums focus on emulators and not on the real hardware !
When you have other questions around these three computers, you can still ask me here. I am very active rightnow and writing a few new guides in german. My english is not the best but to answer questions its enough. I have configured HDDs on every system this year and most of my PC98 games run from there. Also a few x68000 games are able to boot from HDD without using the DD´s and FM Towns HDDs speed up loading times very much.
Japanese computer gamers unite ! ^_^
