[HACTRN]
HACTRN was the top-level DDT when ITS was under timesharing.
The TOP-TOP leved DDT could be considered the NTSDDT, which was what
the person at the console got when ITS went belly up. Or it could be
DSKDMP. The source doesn't say explicitly, and I've heard both stories.
Some people elected to use a disk-enabled NTSDDT as the bootloader, and
some used DSKDMP. (I think, I could be wrong).
Whoa, you're over my head here.
I guess that when timesharing is not enabled, you get a DDT at the console
only? Perhaps a single process only? (A bit like single-user mode in UNIX?)
And what does NTS stand for?
I assume that DSKDMP does different things than DDT. Right?
What's a non-disk-enabled NTSDDT like?
ITS is such an idiomatic system. Is your machine actually running iTS? Can I
get an account? I know of XKLETEN but that runs TOPS-10 (which is nice, but
more conventional -- it even shares a few features with VMS. I think the
syntax for file names and extensions is the same.) I got the MACSYMA manual
through Interlibrary Loan... I enjoyed the description of using ITS. IIRC the
process monitor will say your programs are running, but also crawling, walking,
or flying, depending on system speed.
[What baud rate?]
It's the telephone company. The line "disappears" for gaps of 1-30 seconds
That's horrible. Do voice calls do the same thing? I'd think people would
scream at them to fix this problem.
I guess our phone service is pretty good by comparison. Most of the
complaints about US West seem to be about prices and lack of customer service.
