Hi Rich:
I started as a true MACRO-20 Assembler Systems Programmer on a
DECSystems20-60 myself as well. A good friend of mine actually has a KL10
running today in a virtual machine on his Mac. For those who must have a
COMND jsys fix, he did "something along the following lines:
- I built an Ubuntu Linux VM (Ubuntu is free and fairly easy to set up, so
it was a natural choice -- CentOS might be another good choice, as it is
essentially "RedHat for free".
- Once you have the VM set up (and know how to become superuser):
. open a terminal window.
. become superuser.
. obtain a copy of the Panda distribution containing the KLH20 emulated
DEC-20 with TOPS20 V7 included.
- You'll basically be unpacking the Panda distribution, which creates a
"panda-dist" subdirectory, then you'll enter that subdir, make a couple
of INI file edits, then lauch:
./klt20
- Then there are a series of boot commands that follow, after which, TOPS20
is up and running. All of the rest is in the README (which is a plain
ASCII
text file)."
/jsi (they plural of "jsys" :)
