Doesn't sound like a huge amount of ram to me as
my Data General Mini has
8mb onboard. Now that is a BIG ram card!
I can't speak for that as it may be a 32bit machine. PdP-11s are limited
to 4mb (22bit) and are 16bit machine with memory management to get that
extended address.
Does RT11 have:
Virtual Memory?
Not really though there is a virtual disk VM: that is useable as ramdisk.
I does swapping.
Networking?
Yes depending on version.
How do I run it? I can do dirs and type files etc but
I really need some
docs on the operating system to get anywhere with it. Thanks for the
reply! --
RT-11 is a 16 bit real time OS and falls in the small OS bracket. that
doesn't mean it's simple or lacks capability on that if you need a mor
sophisticated OS for timesharing and multipprogramming there are otehrs in
the (THEN) DEC l;ine up including RSX-11 and RSTS-11. The minima for
running RT-11 is some 16kB of ram and some media (tape, disk, rom) to boot
from and the version running will often require a
standard console port
unless specifically built out. RT-11 has several standard
versions:
RT11-SJ A single job monitor and small
RT11-B Batch monitor also quite small for batched jobs
RT11-FB A version that runs jobs in both forground and background
RT11-XM XM is an extended monitor for extended memory systems
and multiterminal/job applications.
Those were brief to the point of pain.
Utilities are such that most people used to PC- DOS will find most
familiar mostly. A bootable system could have a wide range of
configurations tha smallest of which easily fits on a 256kb floppy.
