Thanks for the info.

I saw a PCI SCSI controller at a computer flea market that had a NCR 53c810
for sale at $89.  It was a no name Taiwan board.  Has anyone else seen or
used a board like this?  Was it any good?  Also are there any cheap buss
mastering PCI SCSI controllers that are compatible with Warp and Linux?

Anybody who's trying to sell you a generic SCSI controller for
that price is trying to take you for a ride (unless that controller
has on-board cache, etc., but I presume not).  I have such a
controller and current price is somewhere in the $30-$50 range.

InfoQuest Computers (on El Camino Real in Mountain View or Los Altos,
CA) is selling a generic '810 PCI board (w/passive termination) for $55.

These folks are at least nominally Linux-aware - they have a four-CD
InfoMagic Linux package for sale, and told me they've sold quite a few
of these boards to people who are running Linux.  They also took the
trouble to ask me which motherboard I use, to make sure it's one with
the NCR BIOS, before they sold me the board.

1. Where to buy NCR SCSI Controller?

Hi all,

I need to find a mailorder place to purchase NCR53c810 chip based SCSI
controller. None of the larger mailorder places seem to order them. The
controller will be used in a Dell Dimension XPS100c Pentium with 16MB of
RAM. Primary OS is Linux, Win95 is secondary. I have a Fujitsu 1606S
Fast SCSI-2 internal harddrive and a SyQuest 44 external drive.

Recomendation would be much appreciated.

Sincerely,

Evan Cheng
