Manabu Sakai is the owner of ARTMIX Japan. He's an eccentric fellow, so try not to ask him too many questions or he'll get into a frizz. And definitely never try to phone him, or he'll put his mother on the phone and have her shield him from questions -- even if you speak Japanese!

I own a TS Adapter and a 40MHz Turbo 040 card. They both work wellto bring the SE/30 up to top performance, but keep in mind that the 040 is less compatible than an 030 upgrade (like the DiiMO), even with the 040 caches disabled. Despite the marginally slower speed, I have the 50MHz DiiMO in my SE/30 at the moment.
