- The 4091 is similar to the FastLane, but it won't work at all unless you
- have the revision 11 SuperBuster. The FastLane will work with the 9, just
- not as well.

- Actually, they might be. I know the RAM on the 4000 motherboard is a lot
- slower than it should be due to some design problem I've never quite
- understood. RAM in a Zorro III card might be faster if the bottleneck for
- motherboard RAM is close enough to the SIMM sockets. If the bottleneck
- is in the processor board or someplace like that then it should be about
- the same speed. You might have a slight speed advantage caching the drive
- from the card RAM, but I don't know. It just makes sense that it would
- be faster.
