G'day all,
Just followed the sale of the 11/05 on eBay (#175655196586) that ended a
short time ago.
It's a remarkably clean and complete machine and am not surprised at the hammer

I was curious what the quad-height card with two ribbon cables coming out the
sides was?

G'day all,
I have just uploaded the engineering drawings for the early PDP-11/05, the
one with the solid (no slots) Mazak lower bezel
and the M7261 with the unpopulated region.
The latest date I can find in this print set is October 1973, Drawing release
11/05-49.

I didn't see it on bitsavers. I don't have any VMEbus gear so no point it

Here's an all-employees memo my dad kept about IBM's part in the success of the
