bring items that are "like" other items brought or part of Bill's

11/34 on the other hand would be a nice complement to my 11/40 project and
there will be space to work on them both simultaneously.

the power supply part(s) I need to complete my 11/40 power supply repairs.

for parts. Also, two from MARCH that while complete were mouse-houses and
so have mouse urine damage; they are less likely to be brought to
operation. But washing them down outside in late October does not seem like
a good idea. Bill, do you have a good excess of Model 33 parts, so I don't
need to bring more than a few TTY's?
I can't have dirty TTY's in the house, but we can work on these in the shed
or garage, but it sounds like you don't want to work on them outside then.
The rat house TTY's have CCU's that could probably be salvaged for parts,
and the CCU green upright card behind it, the fuses, and the motor relay in
the back corner. Also the reader. I have some parts, but I don't know all
what I need myself, some would not be "free" and you'd have to trade for
some things as it will cost me to replace. In short, give me a better idea
what you might need. We can discuss separately

this is not a pressing need and I agree that I can do this in my own time.

leave it to Bill Degnan to coordinate that.
>I know Ian was talking about his PDP 11/05. I have one of those too and it
works more or less, but I need help getting it to communicate with a
teletype and echo chars back to the teletype. I can send ASCII chars from
the 11/05 to the teletype OK, so overall I am close. I have not tried to
hook up a serial terminal yet.
Just these three projects - the 11/34, 11/40, 11/05, plus teletypes would
be perfect for a productive weekend collaboration. I am satisfied with
that plan. Consider that "group 1" -
Of the remaining people coming, please start a new thread to discuss "group
2" if you don't have the desire to be in group 1. Capiche? (yes I
understand everything except "ca-peach").
I have a large amt of "for trade" or sale systems and parts. These are
items from that warehouse haul the other week plus other items I have in
external storage. I remember that Dan Roganti said he wanted a terminal
from the warehouse haul. I sold two of the VT-102's for big bucks. The
rest need at least some work. Dan gets first dibbs if he can make it to my
house or the festivus of what's listed below (sell or trade for cheap). I
am willing to let the rest go for cheap/trades IF YOU PICK IT UP. If you
want me to ship anything you have to paid retail prices as I will have to
run it though my store, etc. Here is a list off the top off my head of
what will be available should you come to the workshop weekend:
- VT-102 (needs power supply or cap repair, have not investigated beyond
"not working"). No keyboard.
- Intel MDS 720 dual 8" drive
(http://vintagecomputer.net/browse_thread.cfm?id=485). I plan to clean
this and photo the jumpers of the Shugart 800 drives within, because this
is a kind of rare drive and the jumpers are probably specific to the Intel
drive controller, etc. MMFM should be documented, etc..
- HP 9835B. Looks good on the inside, bad power supply, cleaned since this
- VT 103 - no keyboard. does not display.
- Hazletine 2000 - Core memory is OK, display is OK, clean, needs power
supply or cap repaired. Promised to Ian or will be trading repair service
of my Datapoint 3300 terminal in trade for this terminal.
http://vintagecomputer.net/browse_thread.cfm?id=481 (item cleaned since pic
- ADDS Regent 20. - Cleaned since photos taken.. Displays a prompt but I
believe there are issues.
- ASR 33 - Needs repairs to tape reader power card, may need a new cap for
the motor (or relay). Easy repairs for an afternoon.
- at least 3 8" drives probably S 801's and related, but I do not know
make/model off top of my head.
- Vector Graphics external dual 5 1/4" drives in a VG enclosure, with
- There is more, but that should get you started.
What do *I* want? - My web site has an "items wanted" thread, but
realistically I don't need anything other than known-working small stuff.
- View SourceThirteen hour day! Jeff B., Jeff J., and I spent most of that time sprucing up the museum exhibits. A few highlights: we cleared out all kinds of junk; replaced the small stanchions and yellow rope with large stanchions and metal chain (which looks waaaaay better); added a second display case into the mainframe room (one is dedicated to UNIVAC and the other to MOBIDIC/Fieldata); and reorganized much of the homebrew exhibit. Also, Jeff J. got all of the books to sell at VCF organized.
