[HECnet] Can we hook this up to a VAX or something?

Correct, an RX02 floppy with a formatted capacity of 512 kB IIRC.

  Absolutely, on the 11/03 CFE.   And any of the UNIBUS VAXen (730, 750, 780,
etc) would directly support an RX01/02 on an RX211 interface.   Such
combinations were not unusual and were supported by VMS.   I've got a 11/730
with an RX02 drive in the garage.   Likewise any of the BI bus VAXen with a
UBA could at least in theory do the same, though by that time 8" floppies
were uncommon.
