[GreenKeys] FRXD tape unit

[Christian Gauger-Cosgrove]

Hi,

Just as a quick question. Was there ever an 8-level version of the
28RT? (I suppose you'd have to call it the 35RT in that case though.)

Just wondering as the 28RT (and the LAXD reader specifically) look
like quite interesting devices.

Cheers,
Christian
