 Are you referring to having the? H-27 drive from Heath? I don't know
 for  sure
  because I've never? seen H27 docs, but the
disk capacity is the same
 as  the
  RX01 (256k)? and I think the interface was made
deliberately
 incompatible, likely? at the behest of DEC. The version of RT-11
 (called? HT-11)  supposedly
  used a different floppy device driver.

 Again, this is based solely on what I've read from various places and
 not direct experience (I have an H-11 with a SCSI controller; no
 floppy; and  it runs
  RT-11 no problem).
