We had the rare thunderstorm here and my Elgar 1100 UPS turned into a
large brick. I've got the schematics for the 1600, but not the 1100--
and I'd like to have it in hand before I go digging into the rat's
nest of heavy wire. I've only had to work on it once before to
replace a 50W zener, but this looks a little more involved.
Can anyone help? If not, I think I can use the 1600 material to
guess what's going on. it's close but not quite a match.
Thanks,
Chuck
Tonight I had one of those I-gotta-tinker moments at midnight. I had the
Atari 2600 laid open, ready to accept the AV mod board I finished up a
couple days ago. I plugged in the soldering iron and poured a capful of
water from a bottle into the sponge. After about ten minutes, I picked up
the iron and poked it at the sponge. No sizzle. Dink around with the
cord and shank. No heat. Ah. This is the iron that I lent to someone
who put melty marks in the cord. I guess it's dead. There went another
disposable soldering iron.
One reason I never graduated to /real/ soldering stations is that I kept
wondering "what do I do when it goes bad?". What do you guys recommend?

OK, that makes sense. So the media itself is compatible, that's good.
Further examination of the tape I have reveals a possible explanation for my inability to read it - it appears that the tape itself is damaged very near the beginning, most likely from having been left loaded in a drive for the last ten years or so. Digging through things here, I did find one other tape. It works in the drive, so at least the drive is working properly.
So, that brings me to my next question - anyone have some extra QIC 600/6150 tapes laying around? I need some to make boot media.

I want to purchase in a few days from now one BA11-SB enclosure (tabletop
type) to swap all the boards of my PDP-11/23 PLUS (my actual enclosure don't
have a box cover). But there is a problem: The box is prepared to put a
couple of mini back-panels, I suppose with the intention of put a couple of
rs-232 ports, or another kind of connectors (network, etc)... but there are
no panels.
I believe that I saw something similar for one PDP-11 24 some months ago but
I'm not sure.
Trying to avoid homebrew solutions... someone knows about a product from
Digital or 3rd party for this purpose ?
Kind Regards
Sergio

Cameron, thanks! I was undecided about whether to enter my Rainbow,
knowing you guys would toast me totally anyhow. But, the geographical
restriction decides me.

For whatever it's worth. My question was how I could get my Mac
Powerbook G4 to serve files to my Color Computer 3; I have not
ordered Drivewire yet, but I probably should do that soon.

No, but close enough to not make much difference. If the modem would
draw anywhere near 100mA over RS-232 just to get the levels, something
is seriously wrong.

The MONIAC (Monetary National Income Analogue Computer) also known as the Phillips Hydraulic Computer and the Financephalograph, was created in 1949 by the New Zealand economist Bill Phillips to model the national economic processes of the United Kingdom, while Phillips was a student at the London School of Economics (LSE), The MONIAC was an analogue computer which used fluidic logic to model the workings of an economy. The MONIAC name may have been suggested by an association of money and ENIAC, an early electronic digital computer.

Hi Jim Battle!
This is Su Yuen from Waggener Edstrom and we represent HP. We were
browsing the Internet for communities of old gadget collectors and came
across a website with your details listed. We can see from the site that
you are an avid collector of old gadgets, which we share a passion for
as well.
HP is currently working to build a ?Virtual Tech Museum? filled with
pictures and stories of old technological gadgets from people around the
world to marvel and share. To encourage more contributions, HP is
currently hosting a regional competition to give away some of its latest
tech offerings. The museum has just been launched and there are already
a few submissions from the community. Being a collector yourself, it
would be great if you could share some of your prized collections with
the community and maybe the story of why you collect them. Oh, even
though HP is funding the contest, the contributions do not have to be HP
gadgets ? they can be from any company.
Do visit the museum at http://www.hp.com/apac/virtualtechmuseum and
let us know what you think. It would also be great if you could rope in
like-minded friends and interest groups to let them know of this! Who
knows, you might even find old gadgets you?ve been looking for to trade
and add to your collection!
Warmest regards,
Su Yuen
I have a large box of RX50 disks that I would like to archive onto
modern media to ensure they are preserved. I've built up a machine with
a 5.25" floppy drive and install DOS and PUTR.
Is the best method to archive them to:
MOUNT B: /FOREIGN /RX50
followed by:
COPY/DEV/FILE B: [filename]
for each of the disks I insert?
I was pondering whether I should use the /BINARY flag on the copy, but
I've not seen this mentioned on other webpages I have read.
Just want to make sure I don't spend the next few hours creating
hundreds of useless images!
Once I have finished I will put anything useful looking online so others
can make use of any treasure.
Thanks,
Toby
