As many of you asked about "mysterious" jumpers of Sonic Buster 8 - I updated the home page with more details about jumper settings in the configuration section. Hope it will clear things up 😀

I believe my card is Rev-A but the BUSHLD jumper is closed by default, since that's the way I got it and I didn't change it. According to that doc it's in IORDY reset mode. I'm a bit confused what you mean by "default" in this case.

Yes, after making successfull pre-release tests in IORDY mode, first rev-a boards were shipped with it by default (BUSHLD closed), but when it was reported to have issues with game Gods in this mode, it became obvious that a safe SB2.0 mode should be the default one (BUSHLD opened). Sorry for the confusion 😀

Wow, that would be an amazing card to add to my new IBM PS/1 2121.

Are there any for sale?
