- I believe you need at least Buster 9. Since our A3000 has socketed
- Buster slot, why not go for a Buster 11?

- I had the 3.1 processor with Buster 9 - BAD COMBINATION as far as Zorro
- cards go. I could get EMplant to work, or I could get Fast Lane to work.
- I could never even boot with the Spectrum board installed.
-
- After much corespondance with the Fast Lane folks, they asked "Do you
- have a 3.1 processor board with Buster 9?". I told them I did, they said
- either get a 3.0 processor, or have someone replace the surface mounted
- Buster 9 with a Buster 11. I had ordered a new motherboard and the
- dealer had the 3.1 processor boards come in - I had taken one since you
- reportedly need a 3.1 processor board to take full advantage of the
- Buster 11.
-
- I didn't go either route, I got a Warp Engine (Which replaces the
- processor board). Now Spectrum works and Emplant works. I sold my
- Spectrum and now have a CyberVision64 with 4 megs RAM. I set the slow
- jumper - no errors or anything. No stray pixels - really nice to use!

- It will not work reliable (at all) with anything less than Buster 9. If
- you have a Buster 11, you will get about 20% speed increase from not
- needing to use the slow Buster mode (reportedly). SOME MACHINES will
- have timing problems even with Buster 11, there are some version of
- motherboards that were timing nightmares. If you still get stray pixels,
- you will have to use the slow Buster mode regardless (as per the
- manual).
