I don't recommend this solution unless you have a very specific
application.
My VT103 is a VT100 plus a Qbus backplane with 4 quad slots.
The power supply is too limited to run anything properly for an
extended period.
Bookmarked until the next PC crash!
Just ask again.
Not after your
programs become large enough. The maximum program
under RT-11 using VBGEXE is 64 KBytes. Under the SJ unmapped
monitor, programs must be much smaller.
How much free space? 48KB?
Figure on about 32 KB at the most. While SJ RT-11 takes less, I always
recommend the FB monitor. Better yet, run the XM monitor and use
VBGEXE to support a 64 KB job when needed. That usually requires
at least 1/4 MB of memory, but a PDP-11/73 with 2 MB of memory is
probably just as easy to find as a smaller system.
All of the PDF
files are available in 21
files of a
total of 12.5 MBytes.
This on my 'round tu-it' list for the spring.
The first time it is a lot to read. After the 100th time, it becomes easier
to remember. I still need to look up questions about device handlers.
From just using a PC at home with XP, automatic
updates seem to want you
to reboot at least one a week.
My wife runs Windows XP already. She turns the system off every night.
So a reboot is not a problem.
