Hi, I also have a beautiful PDP-11/05 to restore. What I'm missing is the key. Is there any possibility that you have the key for yours and I could pay you to make me a couple of duplicates? It would be very greatly appreciated. Greatly, greatly appreciated!

If you'd like to see a photo of it and an expansion cabinet that came with it, look at the following link:

By the way, it appears the the barrel keys for a VAX 750 are the same as those for a PDP-11/45 and PDP-11/70. So, if you need any of these, I have a couple extra.

Nice system.

thread about progress
http://vintagecomputer.net/browse_thread.cfm?id=249

In summary
1) System works enough to hold memory and run simple programs
2) The system by default is set for 20ma current loop 110b console
3) I have a M7856 serial/clock card that can to rs232 communications, which I prefer because then I can use a laptop to download programs/storage.

MARCH has a similar system (my vintage computer club) so if I can get mine running I can also get the system running there, too.

I have posted a lot of useful links on my site from the URL above. They tell you how to set the switches on the M7260 console card and M7856 serial/clock card.

A fellow vintage computerian who lives nearby has made progress on this system beyond where I could get, but we still have not been able to print "hello world" to the screen, our immediate goal.

I am hoping to find someone who has actually gotten an 11/05 to interface with a serial terminal. I am going to keep at it, it's a matter of time.

I believe that the PDP 11/05 (11/10) could have been a personal computer if it were marketed that way, and I hope to be able to explore this possibility. The Kenbak I think pre-dates the PDP 11/05 fyi.

The DEC Professional was a pdp-11 marketed as a personal computer.

Anyway, what problems are you having with your console card?

Also, what car is that in the background?

That's my "other" project... 1962 Studebaker Gran Tursimo Hawk.

Originally owned by my grandfather. In bad shape... :(

I assume you're not asking me what car, did I have a picture with a car in the background?

I found most of the answers, but I have not yet had a chance to work again on this system. I will let you know if I get it running. My goal is to be able to feed the 11/05 programs from my laptop for now.

Oops, I did ask about the car, but I see it was marmotkings picture.

Nice to hear that you are making progress.

Bill,

If you have time, please bring another copy of the key with you to VCF-Midwest! I just got an 11/05 as well - unfortunately, it will probably be arriving after the show.

Thanks,
Jack

First, thanks to Bill very much for making me a copy!!! Second, it's really nice to see that someone has a website with keys. Very nice.
