On that subject, what operating systems did the H-11
support?
Officially, it only ran HT-11, the crippled version of RT-11 that Heath
was allowed to sell. Unofficially it runs real RT11 perfectly well, as long
as you remember to set your [W]H-27s to RX01 mode.
As far as paper tape goes, it'd probably run any of the stand alone paper
tape software that ran on a 11/03.
The processor card in the H-11 was a real 11/03 from DEC; it was shipped
fully assembled and you didn't get to put that card together. All the
peripherals were Heath designed, but they were software compatible with the
DEC versions. As far as the software knows, it's just another 11/03 system.
