Aah- SCO UNIX, how fun. Have a XENIX box that I was trying to do the same thing with. SCO's partition table (DIVVY) is not read by Linux
or indeed any other UNIX but SCO. Furthermore, SCO is one of those lovely companies for which headers are a part of the optional
development environment, and TCP/IP is another add-on (how do they stay in business whan put against xBSD/Linux? the FUD about IP doesn't work
against BSD- been there, done that, adjudicated non-infringing). The best way to get information off of one of these systems is to TAR an archive out to a raw hard disk. Then you
can untar it on another UNIX system. UUCP could also work - haven't tried that route.
The bundle does come with a complete development environment (C, C++, SoftBench) on the Apps CDs. No mention of trial, and SoftBench works
Of course, since HP is giving you the developer discount, you should feel obligated to share anything you build :->.

My email to Merle (at258 at osfn.org) just bounced. Message said there's no
user by that name.
It's very important that I reach Merle or someone at the RICM. Anyone here
on cctalk...? Or anyone who knows how to reach him / them?

Thanks for the heads-up! And a fanstastic reference site.
A clarification regarding the pascal 3.0 / 3.1 / 3.2 software which I'm
looking for, it is HP Pascal for HP 9000 Series 200/300 machines. And is
anyone able to clarify whether the latest version was 3.5, as queried by
Bernd Kopriva in an earlier post?

I have a couple of multibus RAM boards I'm looking for
jumper info or schematics.
There's not much on the boards to identify the model
the first board:
62KB dram board
16 bit data path
the only marking (other than "INTEL") is PWA142779-006
The second board:
256KB dram board
16 bit data path
the original marking was PWA143156-045
this is struck out with black marker and
the number 133292-002 is written over it.
(this board may have been upgraded some time in its life)
I suspect both boards were part of an Intel MDS.
(there was an ICE in the pile that I wasn't able to save)

That's just wrong.
A loaded transformer isn't an inductive load, it's mostly the same type
of load as what is loading the secondary.
Zero crossing is the best place to turn on nearly any load, it may not
be the best place to turn off some loads but for on it is usually best.
If you turn on an inductive load at the zero crossing zero current will
flow. There will be no surge.
Unless there is a serious fault, and even then it is unlikely, you won't
saturate the core of a transformer regardless of how you switch it on.
