U8 Cache used on Zeos and Reply systems.
SX board has a surface mounted SX, no switch, and no L2 cache.
The DX2 board has ZIF socket with a switch block next to it, and an L2 cache.
Cache Memory Socket supports 64 KB or 128 KB cache module You need the latest
BIOS of 1.09.00 or later. 83mhz upgrade really does improve things...
From "wault" on the Vintage
This board was manufactured by Intel and IDT and used over about a two year
period on a variety of 486 systems using a 33Mhz bus in the early nineties.
The board contains a total of 4 rows of 28 pins.
There are 64K and 128K versions and here are some of the part numbers:

card will not operate if more than one processor type is selected.
Two 50 to 19,200 baud serial ports, One 8-bit parallel bi-directional port
The 3350 has 4 drive bays. Two are external (the
top external bay can hold a 5 1/4" device like a CDROM drive). The other
bays are for 3 1/2" devices only. In order to get the fourth bay (the
"upper" "rear" bay, two sheet metal extenders are installed above bay three
(bay three is the "lower" "rear" bay). If bay four is used, you cannot
use the upper front bay for a 5 1/4" device (there is not enough room).
4 MCA slots. One is an MCA video slot, and has the extra connector for the
Clarity 1 card.
NCR 77C22E. with 1MB of video ram. Capable of 1024X768 256 colors.
Clarity 1 Video Board (Bam-Bam?)
There was an optional video board built specifically for the
3350 called the "Clarity 1". It plugged into a proprietary slot, and
was capable of up to 1280x1024. The Clarity 1 has 2 MB. The feature/kit
number for the clarity 1 is 3350-F/K256.
> I have a NCR 3350 with a Clarity I video card. Does anyone
know if there are Win95 drivers available for this card? Or even
who manufactured the Clarity I card for NCR?
Joey Blankenship says:
> MCNCR designed and manufactured the Clarity I card in-house. I
was project leader and developer for the Windows 3.1 & NT device drivers
for this card. I also worked on testing the existing 3.1 drivers under
Win95. They appeared to work fine. I believe that the official
position of NCR is that this card is not supported under Win95, but I'm not
sure. However, we did get the drivers working both by upgrading and
existing Win3.1 installation and installing under Win95. No mods were
made to the drivers.

CD driver on this machine :-(( , because MCA bus ---
You need DOS CDROM drivers to install Win 95 or NT. Take a
You have a 53c94 SCSI host adapter on the motherboard. You will need
two drivers - the CAM driver and the CDROM driver. Your config.sys should
look something like this:
These two statements must be added to the CONFIG.SYS file in the following
order - following any memory manager drivers (such as HIMEM.SYS or EMM386.SYS)
and must precede any other "DEVICE=" statements.
devicehigh = c:\util\ncr\camc9x.sys
devicehigh = c:\util\ncr\diskidd.sys
devicehigh = c:\util\ncr\cd-tosh.sys /d:msc001
Some of the older 1x CDROM drives (like the Sony or the Toshiba)
needed a specific driver (in place of cd-scsi-2.sys).
Another good utility to download from NCR is PUTSIG which
will fix a Reference Disk that's been corrupted by WIN 95.
