searching for TEAC MT-2R tape deck documentation

[Henk Gooijen]

Hi guys,
Today I found a TEAC MT-2R cassette tape drive on a radio amateur
flee market. These tape drives use a tape cassette similar to the
audio tape cassette. The MT-2R tape deck has servo control logic
for tape motion and a CPU with firmware taat makes the tape unit
a block-addressable device (AFAIK).
However, I can only find doc of the MT-2ST, but that is another MTU.

Does anybody have doc of the TEAC MT-2R ?

Thanks,
