[GreenKeys] Mites: TGC-14 vs. TT-299, what difference?

Thu, 31 Oct 2002 23:09:10 -0500

I had a MITE KSR...  Can't remember the Mil ID.  Definitely heavy. 
 Worked okay, but at 75 Baud was the noisiest machine I've ever heard. 
 Even at 45 Baud it was loud.  I gave it to a friend a number of years 
ago, and dunno what became of it.   An interesting machine.

Gave away most of my '28 stuff a few years ago, but still have a KSR. 
 gotta put it back on the air.
