[comp.sys.amiga.hardware] 16 bit IBM slots on 2000

dmartin@uceng.UC.EDU (Dale Martin) (03/06/91)

I was noticing the other day while installing memory on
my 2000(HD) that the mother board has tracks run to the
8 bit IBM slots, beyond the length of the slot.  It looks
like if you added a connector, you could extend your 8
bit slots to 16 bit slots.  My motherboard is rev 6.2.
Does anyone know if this is the case?

Thanks!

yes, you can turn the two 8 bit IBM slots into 16 bit IBM slots by soldering
in the appropriate connector.  *NOTE* you'll void your warranty.

you may also have trouble installing some older 8 bit cards and hardcards,
since some of them assumed that there was empty space beside the 8 bit
connector.

Are you sure about this?!!?!?  I've never heard this mentioned anywhere else?

If this is true, where can I get the right connector? :-)  It sounds like
I could connect one of those fancy 16bit SuperVGA cards to the BridgeBoard
side instead of having to hunt around for the less common 8bit VGA cards.

Hope you're not pulling our associated legs :-)  Have any tech. refs. that
I could dig up???

I don't know where to get the connector but as far as using a 16-bit SVGA in
a 8-bit slot,... That is what I'm doing right now!  I have the 2088 (XT style)
Bridgeboard and bought a clone SVGA card, 512k, for $110 and it works fine,
although at the speed of the XT! ;-(  So you only need the Xtra slot if you
have an AT Bridgeboard (except I've heard problems with some SVGA and the AT 
Bridgeboard)

yes.  this does work.

the connector should be available at well stocked electronics outlets.  you
might even be able to find one at radio shack.

some of the 16 bit VGA cards can be jumpered to work in an 8 bit slot.  some
also automatically detect what kind of slot they're in.  the Logix Microcomputer
VGA card works fine in both 8 and 16 bit slots, and provides lots of high
resolution/color modes.
