I just joined this list, so I'm not sure which of the items I own
would be considered by this group to be rare or unusual, but here
goes...
Imlac PDS-1D graphics terminal, with the large screen and detached
keyboard. Also a second one with the small screen and attached
keyboard, but the chassis and cards are suitable only for parts.
DEC TU56 dual-DECtape drive (goes with my PDP-11/34)
DEC VS60/GT48 graphics display (goes with my PDP-11/34)
DEC RKV11D Q-Bus controller for RK05 disks (on my LSI-11/73 system)
Originally, it only supported 16-bit addressing, but I added the
chip and wires to make it support 18-bit addressing. I have never
even heard of another of these controllers, so I assume it is rare.
Things that I assume are non-rare include an IBM 82 card sorter,
Cardamation keypunch, assorted paper tape gear, and a True Data
card reader (on my LSI-11/73 system).
All of this was operating here at one time or another, but the
clutter has become so bad that it is difficult to get them connected
(or even get at them) these days.
I recently retired, so my #1 job now is getting rid of all the stuff
I accumulated over my almost 50 years in the computer industry. I
have three rental storage units full of stuff and the cost is
killing me! Is it OK to post ads on this list?

No, no it isn't! Best you send me a private message about the items you
wish to get rid of, and I'll make sure only the "appropriate" ones are
forwarded to the list...

Hi Alan,
Nice to see you on the list. If memory serves me correctly, you presented
a talk on (very) high speed data acquisition at DECUS a few decades ago.
DEC RKV11D Q-Bus controller for RK05 disks (on my
LSI-11/73 system)
Originally, it only supported 16-bit addressing, but I added the
chip and wires to make it support 18-bit addressing. I have never
even heard of another of these controllers, so I assume it is rare.
There was also a third party Q-Bus controller that handled 18 bit DMA.
I don?t recall the vendor, but I remember using in on Diablo RK03?s.
I once upgraded a DEC DR11B in a smilier fashion. It was 18bit addressable,
but would not transfer across a 32Kbyte boundary. After reviewing the prints
it turned out to be very easy to add another counter chip fix this. I glued to another
chip dead bug style (downside up) and soldered a few wires. I always liked
the ability to improve things.

I actually accumulating more as I semi-retire. If they don?t let you
post, let us know where you will be listing things.

Cool. Is that mod documented (on-line, that is... not just on some
35-year-old paper)? I have an RKV11D that I've used under RT-11 with
16-bit memory... love to put it on a larger machine.
Good luck on posting your stuff. I'm far away so I'm not likely to be
interested in anything huge and heavy, but I'll take a peek.

Last year I picked up some documentation on the PDP16 family. Does anyone
have any hardware, docs, software or knowledge on it?
I have not had much time to look at it since I got it, and want to see how
it compares to my PDP14 items.

A few more things I have, that I just thought of.
A plastic brightness control knob from an IBM 5110 portable computer.
I removed this a few seconds before I was tasked to smash it and half a dozen others to
bits.
First thing to be done was to 'de-louse' the CRTs by knocking the glass pip off
the end with a screwdriver,
then check and remove any capacitors that might have contained PCB, to be placed in a
tough
plastic bag for incineration. I don't recall if the 5110 had any caps like that, but
other old equipment did.
This was back in 1982, I was doing work experience at IBM and we had to scrap a pile of
(financially)
written-off gear prior to going to the scrap metal place. I also got a 3330(?) head. I
have never gotten
over the 5110's to this day.
Bill Gates autograph. Bill was on a visit to Sydney back in the early 90s to spruik
Microsoft's
involvement with IBM in working on OS/2. I happened to be sitting in the front row of the
auditorium
and when he finished speaking, his 'minder' the CEO of Microsoft Australia
immediately ushered him
to the doors.
I reached into my work bag and grabbed my well-worn copy of the Windows 3.1 Developers
Guide,
a pen, and ran to the door. I shoved the book in his face and to the annoyance of the CEO
he
graciously signed it 'Best Regards, Bill Gates'. :)
IBM 3420 tape drive. I threw a low bid on this, expecting to be outbid. It was getting
near the end of
the auction and I was having second thoughts about it, as it was two states away and I had
found out
how much these things weigh. I was desperately hoping to be outbid but I ended up with it.
The seller
wanted it 'outta here' between Xmas and New Year, so I then had to get it shipped
interstate in that period,
and I was away from home to compound the situation. I managed to do get it done using a
furniture
backloader, those guys almost did their backs in trying to unload it at my mother's
place, in the summer
heat. She gave them a beer for their efforts.
Steve.

Don't I remember you from vmsnet.pdp11 or comp.sys.dec?

LSI-11/73 system)
Originally, it only supported 16-bit addressing, but I added the

They're not common. I have one (not modified for 18 bit addressing).
Is it OK to post ads on this list?
Yes, AFAIK. An early FAQ for this list specifically allowed ads (for
sale and wanted) and I don't think that has changed. Provided said
ads are related to classic computing of course.

I think that counts as pretty rare. I know one othe list member has a
PDS.
DEC VS60/GT48 graphics display (goes with my
PDP-11/34)
This is definitely rare also :)

Ouch, it can be surprisingly much work to get out of :(

Definitely. I don't think it will be difficult to find buyers for the
things listed above.
I wouldn't mind a PDS for myself, but I will not afford it :)
