[GreenKeys] Done lurking; Teletype model 33 KSR/ASR restoration

[Jeff Albrecht]

Hi,

 

I've been reading the list for several weeks. Now that I've retrieved my
teletype model 33 KSR left behind in storage when I moved from Spokane, Wa.
to Mesa, Az. I'm ready to get to work restoring what was once my father's
I/O for an Imsai 8080 S-100 computer. I remember playing startrek(.bas) on
it. I also picked up an ASR as I'm really wanting the paper punch/reader
lacking in our old KSR. My interest in the Model 33s is for display with my
late 70s early 80s computers. I still have Dad's unfinished Altair kit, I've
recently rebuilt the power supply in his Imsai and I've got my old CompuPro
up and running MP/M 8-16.

 

FWIW I recently picked up a Hazeltine 1500 serial terminal. It's interesting
in that it can be configured for current loop. Maybe handy for testing.

 

I've got a page started with some pictures and restoration notes.

I have three Teletype technical manuals. I'm currently reading Volume I
"General Description and Principles of Operation"

 

Hoping to find something obvious. Otherwise is there anyone in the Phoenix
area that might be able to help me repair this? Or does repair work? Or if
not local are there any people still doing repair that I could ship or
deliver this to?

 

So far they both power up, motors running but in hopefully local mode I get
nothing when depressing the keys. The innards don't appear to be very gummy.
The ASR seems newer than the KSR judging by the look of the circuit boards
and components. The KSR is missing the modem which I understand would have
been located in the base.

 

I'm looking for some 

-          Paper tape for the ASR. 

-          Couple type wheel hammer pads.

-          Cover plate that goes under rotary dial with holes for buttons.

-          Volume control knob.

 

Is this greenkeys list archived and indexed anywhere suitable for searching?
I found this http://www.rtty.com/greenkeys.htm but the search cgi is broken.

 

Has anyone written a troubleshooting guide for the Model 33? Good blog post
or ??

 

Thanks for reading.
