That depends on how much of it you drink at once. But in moderation It
should be ok. Your mileage may vary.
I'm not going to sign this one ;)

A regular RT-11 distribution comes with source for the monitors
and drivers, with most all the comments stripped out. You also get the
uncommented macro libraries. You don't get the sources for any
except a few of the utilities (*.SAV's).
A source kit for RT-11 gets you the commented sources to the monitors,
drivers, and utilities. A few things are still missing (MACRO-11
and CREF, mainly because these are now built under VMS.) Believe
me, the commented sources are much more interesting!

What do you mean by "available"?
Freely distributable? Hmm, some of the FigForths fall in this category
(if you want to call them OS's), and OS/8 is there too.
Easily acquired? There are several disassemblies of CP/M-80 and Apple
DOS 3.3 floating around in various places, but these aren't the
"official" sources - they're a disassembly. The PL/M sources to CP/M-80
are also available, though I've never quite figured out how to go from
the PL/M to the executables.
You can get the source if you hand over enough $? Sure, lots of minicomputer
OS's fall in this category.

>5140 PC convertable (laptop) ?
I have several of these... as I mention on my web page (of home systems),
it's not so much a portable computer as it is a *luggable* computer...

<I'm not convinced. I couldn't find any listed as current products on
<www.digital.com or on www.compaq.com.
And WWW.anything.com is the absolute authority? ;)
They are still selling them... I only pass the place (Maynard and LKG)
everyday. Also the OS is still current and planned for future for the
Alpha.
Though Compaq did extend and improve the hobbiest license to include
layered products and more recent versions of VMS.

<successful. The processors were used in a wide variety of machines. The
<VAX is DEC's first 32-bit machine. It used an OS called VMS, which some
<people like a lot for some reason, to the point of still using it. I heard
<that NT has a lot of VMS engineers behind it. An Altair is an early 8-bit
VMS is still used for one reason beyond preference, it's a 24x365 robust
operating system that even memory loss doesn't crash. VMS is still a
production operating system V7.2 or V7.3 I think is current. VAXen are
still sold by Compaq and VMS is also the OS for Alpha along with unix-64
and NT.
Nt has Cutler (only real name) who used to be of the DEC RSX-11 (foundation
for VMS) fame.

Right on target. Most people even then lusted and used some form of
terminal rather than wear out fingers on the front pannel. Even altair
users had terminals of some sort. the most common use for the front pannel
was for code that was not configured for the IO in use (no standards) so you
would single stp through the IO portion, write it all down by hand and then
hand patch it for what IO was in use.

<CP/M. You can download the source, but it's not "Free Software". You hav
<to get a license from Caldera for commercial use.
Inflact the only question was is the source available (no other qualifiers).
Ok then P2dos, a clone that is a direct replacement and improved. there
are others (suprbdos, Zsdos, Zrdos). See my earlier post. The question
didn't qualify commercial or not. If you allow for non commercial/student
use the list is quite large.

Eric-
Check with me next time you're in Denver. I may still have the software
somewhere, but I know I had the CP/M-version documents in my hand about a
week ago.

Interesting... I had a machine in one of the piles at work (I have a
second office, called the 'Annex' where I do hardware hacking for my
group on occasion, and stuff gets dumped there) which I recently
excessed, and it had 'IBM-PC' on it, along with 5150 on one of the
labels... But it had a fair amount of memory in it, and a hard disk
drive in it... Should I have saved it and tried to purchase it from
the company?
