query on DEC TK50 tape drive

[paul]

Can anyone tell me what the new DEC TK50 tape drive is like?
Specifically, I am interested in the controller interface:
is this a TS11 emulator, or does it handle MSCP (or something else)?

Probably best to mail responses directly to me, not to the net.

Thanks,
