[GreenKeys] Kleinschmidt help needed

[Duncan Brown]

Steve,

Try reversing the polarity of your connecton to the TT-107B selector 
magnets.  As I remember, the electrical bias makes the machine polarity 
sensitive.

The KLI machines used 7/8" tape, so that they could type along the 
margin.  But the TT-107 that we have has an adjustment or lever, that 
allows using the narrower Teletype Corp tape and then the TT-107 prints 
over the feed holes.  So you could use the narrower tape in it.

The stand-alone KLI tape readers were the  TT-122 (sync motor) and 
TT-123 (series governed motor). All of the KLI tape readers will handle 
both widths of tape.

KLI did not make a "TD" (transmitter-distributor).  M14 tape readers 
read the tape in parallel, then needed the big "distributor" to do the 
parallel-to-serial conversion.  KLI equipment reads the tapes holes in 
series, so no conversion necessary and no "distributor".

You may have an easier time finding a TT-76 than a TT-122/123.  The 
TT-76 is the KLI complete tape unit: perforator, reperforator & tape 
reader (the TT-107 is just the reperf section of the TT-76). Manuals are 
available for the TT-76: TM 11-5815-238-12 for Operator's Manual and TM 
11-5815-238-35 for Maintenance Manual.

Good Luck & Have Fun,
