I had a beauty of  one  Ray Morrison gave me  when I   had started  our  
computer business.
it was the only one I have ever seen in the flesh. chances are it  on  
turns up in AZ it very well might be that one! ( and I would like to hear about  
it!)

Cory,

I have one of a pair of Model 38 ASRs here that was  used to  
communicate between the WGN Studio in Chicago to the  transmitter site  
near Itasca, Illinois.
Both M38s were purchased  and serviced from Teletype Corporation out of  
their satellite  operation in Elk Grove Village, IL.

The model 38 is the "Lady Kenmore"  of the economy line of Teletype  
machines.  It uses a double  high typewheel to print both upper and  
lower case characters.
The  machine has an extra wide platen to use standard sprocket feed  
14.xx  wide computer paper.  The stand and cabinet is nicely designed   
but mechanically and electrically has many of the same problems of   
it's smaller sibling, the 33 ASR.  When the "door spring" pulls  the  
print carriage back to the left margin, it really slams into the  dash  
pot.  This physical action can cause erratic printing on  the left as  
well as bouncing the parallel contacts of the keyboard,  reader, and  
answer-back mechanism.  As with many Teletype  products, the interface  
is a bit non-standard to be adapted to the  particular user's needs. I  
have a custom designed PC board that  allows an EIA standard interface.

I have one complete M38 and modules  of a second for parts...  I will  
send out a few pics when I get  it running.  I also have documentation  
on the M38 if someone  needs it.
These machines tend to be rare as they were soon replaced by the  Model  
43 in most applications.

Best,
Don   K9TTY

P.S. The computer paper is very expensive.

Hi guys,

I recently  had a look at a Model 38 ASR with its matching desk. A  
beast, to be  sure. Now, the truck was already full so it didn't come  
home with me  (at least right now), but I'm curious what the background  
is on this  model. Google isn't much of a help. It appears to have a  
type  cylinder like the 32/33 series. Did it operate at higher speeds?   
What was the target market? Anything unique about this  model?

Thanks,
Cory
