PDP-9 stuff from my road trip a few years ago

[1944GPW]

It was a nice morning so I thought I'd take photos of the PDP-9 stuff I recovered in 2016.

Hardware: DEC A-D converter and some additional flipchip logic. The sockets in these are single-sided. (There were a number of other PDP-9 flip chips I grabbed which I have taken photos of previously).
Also some PDP-9 5-1/4" vac-formed fascia panels. I use these on my H960 racks with a 3D-printed adapter clip. There is a vac-formed bezel for the PDP-9 paper tape reader/punch somewhere too but I can't find it at the moment.

A few boxes and trays of paper tapes including DEC-labelled PDP-9 system tapes as well as a lot of field-punched tapes.

 

[1944GPW]

Some docs including PDP-9 engineering diagrams, software manuals. I have no idea why there is a PDP-15 doc in with this, I don't think they had one.

Last four PDP-9 docs

It looks like there are quite a lot of interesting papertapes there. It would be nice if you could make a list of all tapes and compare with what they listed at RICM pages. If there are new items on your list these should be dumped! Do you have a paper tape reader?

PDP-15 and PDP-9 are similar software wise. So I think that explains why you found the PDP-15 software manual there.

Do you know the status of the remaining stuff on the location you picked this up? I remember a partial PDP-9 there in sad state. Maybe LCM-L has the funds to take care of it? Or they have enough spare parts already?

Very nice find! Someone that owns a PDP-9 should take care of this!

I would really like to have those frontpanels since I miss those on my PDP-9, any chance that you would part from those?

There is a list of paper tapes that we know about here: http://www.ricomputermuseum.org/Home/equipment/dec-pdp-9
Like Mattis and Anders, I am very interested in any of the paper tapes that you have.

There is a lot of PDP-9 documentation here: http://www.bitsavers.org/pdf/dec/pdp9/
Could you look at the documentation that you have and see if there is any that has not already been scanned and put on Bitsavers?
You have docs on the MC09/G920 that I have never seen before. I would be very interested in having a scanned copy of those.

I am working on the PDP-9 at the Rhode Island Computer Museum in the USA.

Mattis and Anders have been helping with this work.
