- You are talking about Opus Systems Personal Mainframe SPARCcards.
- We have the SS1+ card, but they have a SS2 card available now.
- I have serious doubts that it would actually work. It is pretty hardware
- sensitive.

- Actually, you route your VGA card through the SPARCcard and it passes
- the signal along when you are using the PC, and then takes over when you
- are running the SPARC. Basically, you hit some hotkey 3 times (shift key
- in our case), and it toggles between DOS and SPARC (SunOS 4.1.2 works
- fine on this board).
