Out of curiousity, what are the hardware requirements

PDP-11?
Just about anything that will run RT11, as far as I remember. An 11/03
and
a pair of RX02s should do fine. I used to run it on an 11/23.

OK, this brings up
two questions. Can it use RX50's (I'm guessing not), and
is it available for download anywhere? I can manage RX02 (assuming the
drives work), but would prefer to use RX50 since they're already in both
PDP-11's I've got at home (RX02 is buried in storage).
Jerome Fine replies:
Having never used Pascal very much, I have not followed this thread very well,
but I can comment on this question. RT-11 does not normally distinguish
between different devices. If the RX50 is DU0:, then the command:
ASSIGN DU0: DK:
tells the application program to open any files on the default DK: device from
DU0: and if the file includes the device name (usually always allowed) such
as DU0:FOO.PAS, then that file is used as the source, etc.
In general (almost always), applications NEVER know anything about the
internals of a device driver - which is why a device driver is used in RT-11
to separate the application program from the hardware and let standard
I/O calls to RT-11 and then to the actual device be transparent.
A friend of mine uses Pascal-2 V2.1F from Oregon Software in (was) Portland.
The date mentioned on the manual is August 1st, 1988. Does this help at all?
Also, there is a question if the work was completed, but some parts were made
Y2K compliant. Anyone care or even interested?
Sincerely yours,
