<div>So we have not had any takers on the subject.</div>
<div> </div>
<div>So since we had a great discussion about the TRT-1, here is the answer for
that series.</div>
<div> </div>
<div>TRT-1A</div>
<div>TRT-1B</div>
<div> </div>
<div>There was a C added to the end if it had the color rack added. The A
version had a number of different layouts. It was the very first machine
that RCA really mass manufactured. The layout would change and the servo
amps were a number of versions. The design by the B model was
stable.</div>
<div> </div>
<div>Now there were several other accessories that were available. Solid
state Capstan servo that was the Switch lock. Then Pix Lock that did the H
lock. Finally a monochrome ATC system.</div>
<div> </div>
<div>So does anyone else know the other models?</div>
