It makes them STINK!
Actually either one makes them stink! ;)

Does anyone know where I might find prints for a PDP-11/70? Like complete
prints? I was intrigued as I studied my own 11/70 with the possibility of
implementing an 11/70 in modern high-speed discrete logic.

Today I spent 8 hours moving stuff from one smaller storage unit to a
much larger one and found goodies I long forgot about. I have not seen
the back off this storage unit for almost 3 years. Here's a list of some
items;
1. PET 2001 series 2001-8 in good shape, will take home and test it.
2. CBM 2001 series 8 machine has been modified with new keyboard in
place of tape unit and smaller keys.
3. Commodore model C128D in great shape.
4. TRS80 model 1
5. PolyMorphic System 8813 model 8813/1 with wooden case.
6. CPT disk unit 8 ID# 931203
7. ADDS Ultimate model 25
8. SOROC model IQ120
9. Franklin PC8000 in great shape
There were a lot more plus I still have not finished moving items yet.
If I was not moving I would get me a heater and play also.
Perhaps slightly off-topic (other than being a resonably old part), but
would anyone around here have a datasheet (or, at least, a pin-out) for an
HP HDSP-2490? This is an odd, 4-digit, 5x7 led matrix display. It's in a
28-pin dip, and looks to have some intellegence built in.
The answer from HP (nee Agilent) is "long since obsolete, we know nothing".
Thanks...

You do know about Mentec's new-technology pdp11 processors, right?

The last time I even tried to take a vacation, I saved up
>from January till June to attend AudiFest '98 at Pike's
Peak. The turbo blew in the quattro a week before and it
took all I'd saved to fix it. Including selling the tickets.
Coupled with a meager $30k yearly as a sysadmin running an IIS
webserver might give you an idea as to the dreadfullness of my
circumstances.
Were I only willing to leave God's Country, I know I could
better that salary in a heartbeat...
