I have an Outbound Notebook which takes a camcorder-style 12v 2 Ah
battery. The Outbound's power adapter, which is used to both run the
unit and charge the battery is 22v, 0.82A. Unfortunately, I don't have
the adapter or anything similiar.
What I would like to know is how forgiving the Outbound and its
battery would be if I used an innapropriate adapter. I have an adapter
that puts out 14v and 1.2 amps. Am I correct in assuming the 14v would
suffice for charging the batter (not running the unit)? What about the
1.2Ah, though? Will the extra amperage do any harm?
Thanks.
Tom Owad
P.S. Anybody have a 22v, 0.82A adapter for sale?

We had quite a few when I was growing up (ds21's, mostly, including a
wagon) and they were maintained by a Citroen-only shop, but still, I'd
rather walk. (Citroen is pretty darn close to Citron, which of course
means Lemon. 8^)
And to relate it to classic computers, it was about 10 years ago that I
drove through downtown SF in a Citroen with a flat tyre and Jerry Pournelle
and several other muckity-mucks from McGraw-Hill(?) in the car with me.
Very embarassing...

I got a VMS ver. 5.4 "Grey Wall" myself with the 'Great Haul' a while back.
I took an inventory of all the manuals based on the first several pages of
the Introduction to the Master Index (found in General User vol. 1)
I discovered at least four binders are missing. Not too bad considering
there seems to be a total of at least 29 grey binders in the whole of the
three manual subkits. They probably were left on somebody's desk at the
southern college from where the previous owner obtained my VAX 11/750 back
in '90 or '91.
Would anybody have just odd parts and pieces of the VMS 5.4 manual
collection? If so, would any of you be willing to part with several to
help complete mine?
Here's the manuals/binders I'm missing:
General User Subkit Volume 4, "VMS DCL Dictionary" (may consist of vol.
4A and 4B in one _or_ two binders as hinted by a footnote.)
System Management Subkit Volume 3, consisting of : "VMS Access Control
List Editor Manual", "VMS Audit Analysis Utility Manual", "VMS Authorize
Utility Manual", "Guide to VMS System Security" all in one binder.
Programming Subkit Volume 7A, consisting of: "VMS I/O User's Reference
Manual: Part I" and "VMS I/O User's Reference Manual: Part II" both in one
binder.
Programming Subkit Volume 7B, consisting of: "VMS Delta/XDelta Utility
Manual" and "VMS System Dump Analyzer Utility Manual" both in one binder.
Later, I may ask for help in completing my RSX-11M ver. 4.1 'Orange Wall"
when I get around to doing a precise inventory. Seems to be several of
those binders missing. (At least my RT-11 ver. 4.1 manual set seems quite
complete :-) )
Thanks loads for the help!
Regards, Chris

Sedt? it was PC huge. To get that functionality it didn't need to be
60+k of code. Even VAX EDT is smaller! Most of the EDT clones FYI are
about 12-15k of 8080/z80 asm code and about 22k if written in a C
compiler.

I don't know the outbound, but I can offer the following thoughts:
To charge a 12V battery with a 22V power supply suggests some internal
regulation, in which case 14V probably wouldn't work. On the other
hand, it probably would do no harm.
You don't say whether the 22V is dc or ac - if it's ac, dc might work,
but if it's supposed to be dc, ac could damage your machine.
Most power adapters are constant voltage, and quote a maximum current.
So the requirement is for 22V, capable of at least 0.82A. A power
supply that can put out 1.2A (not Ah) would be ideal.
> P.S. Anybody have a 22v, 0.82A adapter for sale?
I could build you one, but shipping it to the US might be expensive :-)

Not at all similar, I'm afraid.
The 4051 was a 6800 machine, and the 4052 used four 2901 chips and a
homebrew sequencer to give you a 25MHz 6800 with some extra
instructions. More about this - and the disgusting piece of
pessimisation they included - at my talk at VCF...

True. The reason was, I have _no_ HP disk drives, but I have _three_
8050s (one working, one in bits, one badly mangled), not to mention a
4040 and a 2031 (which would also work), and at least six PETS. So the
Commodore stuff was the obvious choice.
And Tony is also right: I don't have the CS/80 protocol.
Besides, most of the problems were with the Tektronix lacking facilities
for opening files, loading and saving named files, etc.
Not to mention its asserting of IFC just when I didn't want it to...

Agreed. Lots of PETs were used in commercial/scientific applications -
probably because of the GPIB - and there are even books like West or
Osborne & Donahue in the library here at work.

I want to apologize to you for accidentally sending you an anti-spam

quite funky.
Again, I apologize.

Would you still happen to have this cardfile available?
