Yesterday I scooped an AT&T PC 6300 Unix machine
on its way
to the dumpster. Got it home, powered it up, and now I know
why. It displays "Parity error on system board" and locks
up.
It seems to have 1MB of RAM, half socketed (36 81256's).
So I yanked the socketed chips, and tried again. Then
it did almost the same thing, but displayed a running
count up to 512K before that parity message.
Does this box have a BIOS setup program onboard or must you use a
configuration disk? (if so do you have the disk?)
I'd try turning off the parity check on the unlikely chance that the parity
check itself is loopy . . . other than that, you've got a _lot_ of soldering
to do ;>)
BTW ISTR that one of our "customers" abandoned a 6300 in lieu of having it
repaired. Contact me off-list if you're interested & I'll dig it out of the
back room and check it out again.

The AT&T setup files (in case anyone needs them) are located for download at

Me thinks he might have a 6286EL

Sounds like a 6300+ to me... there was NO setup disk. Just dip switches
like on the 6300's and XT's. There are no IBM AT compatible slots.
Just Olivetti designed 16 bitters (this thing was designed before the
AT Standard.)

Three things never anger: First, the one who runs your DEC,
The one who does Field Service and the one who signs your check.

Nope. No NVRAM either. Just a bunch of dip switches like an XT.
Check the NCR web site for info.
I had a 6300 and always wanted a 6300+. BTW, the story I heard is
David Korn wrote the Korn Shell on a 6300+ for System V.
It was used at AT&T as a single user development box for a while
until the workstations began to appear as AT&T's Bell Labs moved from
Vaxes and 3b's with BLIT's and 630 terminals to 7300's and later
to Sun Workstations.
