Subject: Looking for a few ISA cards
Hi everyone. I'm looking for an isa VGA card, a
sound card, and an
ne2000 network board. I have 1 16-bit slot and 2 8-bit slots to play
with. This is for an amiga with a 286 bridge board. If anyone has
any they'd be willing to part with, please let me know.
I have a sound blaster and an ne2000 board, but they're both 16-bit.
The amiga 2000 motherboard is setup for 16 bit slots in place of the 2
8-bit slots. The sockets just aren't there. (Not sure why commodore
thought this was a good idea) I could find a donor board and solder
in the extra connectors I guess.
A more interesting solution though would be a 16-bit isa extender and
an expansion chassis. I could put a passive backplane in another
amiga 2000 case and have more 16-bit isa slots than I could fill.
Alas, these extender cards are ridiculously expensive. If you know
where to get these bus extenders new/used at a reasonable price,
please let me know.
So I guess the best solution for now would be a 16-bit vga card and an
8-bit ne2000 board. I'm not sure if the bridgeboard can emulate a
sound blaster through the amiga's sound system, so maybe that's not
needed at all.

Easiest thing to do is solder in the 16 bit headers on the (2) 8 bit slots.
That is what I did on my A2000 a few years ago for the 286 bridgeboard. I
have downgraded to an XT bridgeboard recently to be different (and I owed a
friend a favor and he wanted the 286).
For the extenders just desolder (or find new) 16 bit isa slots and cleanly
break off the extender part. The ones I tried almost seemed like they were
made to snap in the correct place, I then just filed it down a little to
look nice.
Failing that you might as well use a common 16 bit network card and a not so
common 8 bit VGA card (just snagged another one of those the other day
actually, have yet to test it). Some 16 bit VGA work in 8 bit slots (some
ATI anyway).
There are 8 bit isa soundblasters.
