Need help with an A2000 accellerator card

[melott]

I picked up this A2000 accellerator on EBay.

Its a 'Harms Professional 3000 or 3500' I can't tell
from the pics.
Anyway.. what I need is a manual (in english).
I D/L'ed the install disk but there's no info on jumper
settings etc.
I suspect this might be the 3500 model and if so I
think the 68000 chip needs to be removed from the MoBo.

Any help will ge greatl appreciated

According to the note on the Amiga Hardware Database, the CPU only needs to be removed on the A2000-A.

Ummm...whats an A2000-A  ?? (what does the 'A' mean?)

Also if someone that speaks German could translate
the jumper settings into English??

The 2000-A is the early German-designed version of the A2000. It's more limited in motherboard RAM, and has very restricted video and CPU slots. I think the only released 2000A's are those with Rev.4.0 motherboards and earlier.
