Hi Joe
You might let these folks know about these. They
have a need for one of these:

Does anyone have any info on this computer? I've found one at a scrap place
and they're supposed to be getting a several more of them in. I pulled some of
the cards from this one and they're marked Sperry-Rand. I checked the date codes
on some of the ICs and they were all dated 1977. I pulled eight large core
memory boards out of this one. Any body know what the memory capacity is on
these?

Dwight,
Excellant suggestion! My father is also interested in disposing of his Teletype systems
and they're looking for some of those too so I might be able to load them up.

Oh boy, you're gonna get a few responses here saying *that*! I need a
Teletype for my PDP-11/20. And, since I just found out I was getting hired,
I might actually have money in a month or two.
How many TTYs do you have, and where are they?

They're not mine, they're my father's so it's up to him about what he
does with them but I expect $$$ are always welcome. I think he has four complete units and
the guts for another. I'm pretty sure that there is an ASR-33 and a KSR-33 but I
don't know what the others are. I'm trying to get him to dig them out and make a
list. He also has a bunch of manuals, tools, paper tape, roll and fan fold paper for the
printer, etc etc. They're all located in the central Florida area. If you get down in
this area on vacation, I'll give you directions of how to find him.

If you intend on using it to read in paper tapes, you'll want to make
sure it has the standard DEC "reader run" relay enhancment (extra
circuit and current loop to let the CPU step the reader one char at
a time.
Ordinary if the TTY comes from a DEC machine; atypical if it was used
for simple text input/output.

How do the ASR33 and friends compare to the PC05 in terms of speed and
reliability?

I have had no reliability issues with either, presuming the ASR33
is well adjusted. The trick is that there's better documentation
out there (now) for cleaning/adjusting the ASR33, but I've found
the PC05 reader to need nearly none (had to deoxidize the light
bulb holder once).

Ah, I thought it was relatively slow. Well, I don't need a DEC-compatible
TTY then. I have a PC05.
