Interesting day at the auction.

The Data General Aviion 9500+ went for a whopping $17.00. The pallet of
ultrasparc's went for $300, (way over my budget), but I walked out with a
pdp11/73 in a BA11 case.

And the mystery box. A black DEC BA11-m case with a dark camo-green panel and
3 qbus cards, a DRV11-b, a dual qbus card with two 20 pin berg connectors. No
I.D. except for the stencil EXTREL 500869 C-81, I have no idea maybe a floppy
controller or a serial card.

And finally A Quad height Qbus board with a Motorolla MC68000l12 processor and
a paper label at the bottom of the board that says:

590139
BUS CPU
REV A
EXTREL 2MHZ

It also has 2 Zilog Z80 chips a
Z80B CTC and a
Z80 UART

So is this a motorola 68K Qbus board??

Can Anybody enlighten me. Any documentation, a quick google search found very
little .It probably was part of a instrument that was sold in another lot.
I picked this one up as I spotted the ba-11 qbus box.

Cheers

Tom
