I'm investigating getting MULTOS/8 running on the 8/e here at the museum and I thought
I'd start by getting acquainted with it on SIMH.
I've picked up the disk pack from Dave Gesswein's site here:
https://www.pdp8online.com/pdp8cgi/os8_html?act=dir;fn=images/os8/multos8.r…
and the manual here:
http://www.pdp8.net/os/multos8/
MULTOS as currently configured on the RK05 image appears to be set up for two terminals
and everything listed in BUILD looks to agree with respect to the SimH hardware
configuration. I set up a password file per the instructions, and after I set the DATE, I
do an:
.R MULTOS
And am greeted with:
HELLO !
THIS IS THE MULTOS/8 MULTI-USER OS/8 TIMESHARING SYSTEM
CREATED BY COMPUTER METHODS
7822 OAKLEDGE ROAD
SALT LAKE CITY, UTAH 84121, USA
PHONE 801-942-8000
PLEASE INPUT TIME IN 24-HOUR FORMAT
(E.G. 0925 FOR 9:25 AM AND 1935 FOR 7:35 PM):
1601
THANK YOU !
THE SYSTEM IS NOW TIMESHARING
TYPE CONTROL/H TO LOG ON.
At this point, the system becomes unresponsive; CTRL-H appears to have no effect. AC and
MQ seem to be incrementing over time as the docs describe.
I've poked around and in PARAM.PG, the address of TTY #2 is set to 32 (VT78?), rather
than the 40 I'd expect. I changed this and reassembled the JOBS device handler, and
then used BUILD to rebuild the system using it. I'm still getting the same behavior,
however...
I have a bit of experience with OS/8 (but I'm not an expert) and nearly zero
experience with MULTOS, so before I start debugging in SimH I thought I'd check to see
that I'm not doing anything intensely stupid here...
Thanks!
Josh
