On that subject, what operating systems did the H-11
support? I have one
sitting in my collection, complete with paper-tape reader and 8" disk
drives. Never had the space to set it up until recently.
Mine runs RT-11, but since it's "just" a PDP-11, it'll run any -11 OS
that your CPU supports. I think the original H-11 processor was an
LSI-11 (11/03), but I'm not sure since mine came to me with a KDF11
(11/23) and was brutally extended to a hex-width backplane (AB-AB-CD)
to accommodate an RLV11.
I have since removed the, um, customization, and it now fits inside
its original enclosure, but I've never gotten the H27 floppies to
work. It works fine with a DEC RXV11 and RX01, but not the original
Heath controller.
