[QuadList] Unknow mystery quad modules????--Sold totheonlybidder

[Don Norwood]

Hi Chris:

Yes, RCA did build a variety of octaplex machines and I have some literature on them which I will try to get posted soon.  Also some application notes from Ampex for their rotary head instrumentation recorders.  Some of the early RCA designs were surprisingly primitive.

Note that the FR-900 can be either quadruplex or octaplex, allowing for either one or two channels.

  I read the brochure.  It says that the machine can play back a tape made on an AR-500 or AR-550 airborn recorder.  I had heard taht RCA had made an octoplex machine that was used as the basis for their portable quad.  What does anyone know about these machines.
