Jerome Fine replies:

Controller Model Max RD5n Drive
------------------ ------------------
RQDX1 (M8639) RD51
RQDX1 (M8639-YA) RD52
RQDX3 (M8639-YB) RD53
RQDX3 (M7555) RD54 - RD3n drives also allowed

NOTES:
(1) RQDX1 must be the last board in the Qbus (i.e. ONLY one allowed)
(2) All RQDXn also allow the RX50
(3) RQDX3 also allows the RX33 and RT-11 can FORMAT an RX33 media

Any other questions?

Sincerely yours,

Jerome Fine
