https://theretroweb.com/motherboards/s/ncr-class-3421I'm interested, what would the shipping be to 13904 Binhamton ny and any packaging costs..
This is an NCR system with MCA slots, 386 SX.
What makes it interesting is it has SCSI on the motherboard, with both internal and external connections, the maximum RAM (8Mb), and a
Cabletron Ethernet card with the standard RJ-45 jack and a working
Conner Hard drive.
I modified the onboard VGA connector, adding an opening on pin 9 on the second row, so current VGA cables fit now, no custom cabling needed.
It boots, displays POST info including that it detects 8Mb RAM, and has
DOS 6.22 and Windows 3.0 installed, though I commented windows and the antivirus out of autoexec.bat because they run glacially slow. They can
be enabled by uncommenting or run manually by typing win. The SCSI and ethernet have the ADF files installed. @7F4D for SCSI and @5608 for
Ethernet, which has a RJ-45 jack. I managed to install a packet driver,
and DOS based DHCP, and it got an IP address, and pinged briefly, but
then stops. It appears the hardware works and it is a software problem.
These were used as POS terminals back in the day, but would work fine
for retro-computing DOS games or (very slowly) Windows 3.x. I also read
they take OS/2 up to version 2.0 but have not tested.
I am in the Los Angeles area, in case anyone wants to pick it up, since
these older models are all metal, so shipping might cost more than the computer at this point.

Thought this was a classless society...

Wow, looks pretty flexible and capable.

Nothing mind-shattering
Errata, nothing huge
1x 16-bit AVE slot
3x 16-bit MCA
Power connector could be for a 50/70 style PSU, -OR- like the Model 90
PSU with the edge card socket. I dunno.
Looks to be two "SIMMs" worth of memory soldered to the board, unknown
size. But each "SIMM" has 8 chips, plus 4 smaller chips. My SWAG is 8x
data, 4x parity.

I see I'm not the only one in this group who appreciates puns. Classy.
Below Class 3421 it says Model 2010. If that helps narrow it down.
It does indeed have what appears to be an edge connector between the
power supply and motherboard, no fan inside the PSU, just one behind the Conner HD and to the side of the PSU which vents out the back. 2 MB on
the motherboard, 3 slots that look like extra tall 30 pin SIMMs, but are
said to be NCR proprietary, for 8 MB total. Empty socket for 387 marked
U72, and an empty slot for a 486 upgrade, also said to be NCR proprietary.
