> How many bays does the case have? What are their configurations?
Are they internal? external?
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
There is also a SCSI connector on the back of the system for external
There is a socket on the non-SX version of the processor
board for a
128K cache (optional).
The SX board has the SX chip surface mounted and no
switchs. The DX2 board has the CPU in a ZIF socket with a switch
block next to it
Cache Memory Socket which
supports 64 KB or 128 KB cache
module You need the latest BIOS from the BBS: 1.09.00 or later. 83mhz
upgrade really does improve things...
4 MCA slots. One is an MCA video slot, and has the
extra connector for
the Clarity 1 card.
> What kind Video subsystem does it have? What is the chipset?
NCR 77C22E. Capable of 1024X768 256 colors.
There was an optional video board built specifically for
called the "Clarity 1". It plugged into a proprietary slot, and
capable of up to 1280x1024.
> How much Video ram does it have?
The 77C22E has 1 MB of video RAM. The Clarity 1
has 2 MB. The feature/kit number for the clarity 1 is 3350-F/K256.
> How can i do for install easely install one of the two ? ---
No CD driver on this machine :-(( , because MCA bus ---
You need DOS CDROM drivers to install Win 95 or NT. Take a look
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:
Some of the older 1x CDROM drives (like the Sony or the Toshiba) needed
a specific driver (in place of cd-scsi-2.sys).
