- Nope. But I doubt it's the PSU. I'm guessing it is due to the fact that SASC
- 6.0 is both very processor and hd-access active. And that IDE hd transfers

- the display is suffering from a very high load on the bus. Have you tried
- getting a GVP SII (v4.5) or A2091 from a friend and running SASC of that?
