These things are GREAT Bridgeboards, but they are VERY finicy to get running.
First of all make sure you are using parity memory on the Vortex. These will be the full 9 chip SIMM's, not the 3 or 8 chip versions. Secondly make sure you turn off the Amiga CPU caches when running the Bridgeboard software. Try switching slots as well. Mine will only run reliably in the top Zorro slot in my A4000. It will not work properly in the other slots.
I have the German version of the manual which is Huge. You can Google translate the appropriate parts as needed. Keep trying they are very cool to use and very reliable once you get them running. Keropi can also be some help. He helped me a great deal to get mine working.
