[GreenKeys] M38ASR

[Jack]

I worked on Model 35 RO’s at Holiday Inn’s in the early 70’s. They were used

for reservation confirmations. These machines always had a lot of 

paper jams…they used sprocket feed multi-copy carbon paper.

 

We were lucky in those days that we could get replacement, brand new

33 typing units from Western electric almost overnight. Although I do recall

one of my fellow TTY guys replacing the compressed-type 33 typing units

with standard ones (he paid no attention to the print). It drove

the customer nuts!

 

I’m pretty sure Ma Bell did not market the 38’s. Never saw a commercial

37 installed, either. The clock was ticking on Teletype products by the late 70’s.

TKS to Jim and Jack for their comments on the 38's...

 

I don't. expect more than a handful or so of GK members

wud have one of these machines...

 

It is interesting tho, to look back on the engineering

efforts put in to developing this machine...

 

When I think back some years ago, I believe the Holiday Inn

hotel chain used a "RO" version of the '38 in their own enclosure 

to print reservation forms...

 

Any one know approx how many of these were built?

 

Our company never pursued this product line, but only

offered sprocket feed private line M33ASR's as computer

I/O devices...

 

Interestingly, the discussion of the "Compressed" print for

the M33's brought back some shop memories...

 

We did receive an order for a quantity of sprocket feed 33's

that were to be modified for "Narrow" print, I think 12 char.

to the inch...

 

I believe the result was a 96 character line length...

 

As far as I can recall, it used a "NU" typewheel...

 

It also involved in addition to replacing the typewheel,

a change in the spacing ratchet, and possibly the

carriage spacing belt and drive pulley...

 

Perhaps Wayne mite comment, on the above info,

as I forgot to take my memory pill today...

 

However, I can tell you this with certainty,

the typewheel positioning adjustments, vertical

and rotary, have to be rite on the money!

 

The characters are so close together, no room for

marginal adjustments...

 

I was lucky, the 33's were straight from Teletype and right out

of the box...

 

I wud never want to install a compressed print kit on

a "Tired" or well worn unit!

 

Thanks for listening!

 

Cheers!
