Yow!!! That means maybe it will run FLEX! [insert Homer Simpson
impersonation]
Woo Hoo!. Dang! I can just imagine running FLEX at 25Mc! Its performance
over a 1Mc 6800 must have been blistering!
Yikes!! I think I may have seen some boards from a system like that one
in a junk heap last week! It used four 2901's eh? Hm, I'm gonna haveto
revisit that particular junque pile . . .

What if I hooked the charger directly to the batter? Would the extra 2v
be a problem?

Both the intended adapter and the one I have are DC.

I'll probably end up with an explanation that's way over my head, but -
How do you build one?
Thanks.

Would you be able to save any complete systems?

Well, then it's probably from the government. There's not too much pretty
stuff from the government (going in and coming out). It would be
interesting to see what's on those HD's. If it doesn't' have a monitor, it
could have been some type of mainframe.

I'm heading down to this guy's place sunday to take a look around. He
offered to let me make multiple trips so I'll prolly go down, make a
list, nab what I want, and let y'all know what's there for the taking
and maybe I can go get some of it for you and ship it out (within reason
of course).

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 :-)
Philip.
