[GreenKeys] Mag Tape Terminal

[CRFandt]

Larry,

I was given the Mag Tape Terminal which Don had. It had been given to me 
by a retired telco friend who was in the same ham club as me. I got it 
from him about 1985 along with spare parts and three or four 33ASRs. The 
local telco cleaned out a corner of their garage around mid '85 and he 
snagged as much as he could. Predecessor company to today's Windstream 
telco (nee Alltel; nee Midstate Telephone; nee Jamestown Telephone Co.). 
He said that unit came out of our local Sears store. Sent the day's 
sales numbers to Sears Chicago HQ during the wee hours of the night.

Oh, now what was that model #?  4550?  The 37ASR went to a ham down in 
nearby Warren, PA along with its UCC-26 (I think I recall it was a -26), 
so I couldn't get the system working. Ham later died suddenly and his 
stuff got spread to the four winds, so to speak.  I gave the Mag Tape 
Term to Don six or eight years ago.

Those certainly were special tapes. And I think Mag Tape Terminals were 
not too common at all, with Sears seemingly the major (only?) customer. 
Never have seen another one before or since I had mine. You, Larry, are 
the _only_ other person to mention the MTT other than Don and my late 
ham friend who's SK 20+ years ago.

Still have three of those 33s in varying conditions.
