Technically it was lost over the Atlantic Ocean and reports of some sort of computer failure 30 minutes before they vanished.
It's a shame they were using Amiga's, they'd have made it to France 1 hour earlier than expected!

It seemed to me that Radio Shack stopped selling plain perfboard a year or
two ago. Yet a couple days ago, I found lots of it at the one a few
blocks from my house. Anyone else know anything about this?
Solder-ringed perfboard is good for stuff, but I find plain perfboard nice
for building up stuff that's not necessarily a circuit.

Hi,
An acquaintance in (maybe) India, has dozens of HP 700/32
keyboards he'd like to continue using ... but by attaching them to
modern equipment. He's done some initial work trying to figure
out the signals/protocol, but hasn't solved it yet.
I pointed him to CC here, but he seems reluctant to join.
He writes:

If anyone is interested in corresponding with him, please email me offline
and I'll try to put you in contact with him.
thanks,

Sorry, that was supposed to say

After a long wait, and paying unexpectedly high fees to the freight
clearance company I finally have my hands on my 029 keypunch. To my
surprise it has an extra wide punching station which apparently is an
extra read head which allows it to be fed with ready-punched cards and
the text to be printed at the top of the card. An interesting bonus.
It uses the same wire relays which have been discussed here recently,
and fortunately I have a 303 ammunition box full of spares including
many of these from a verifier I broke up some years ago which I kept
for my 836 punch.
The rating plate shows .4kVA which is more than my Flexowriter
transformer can handle so I have ordered a modern yellow industrial
110v socket so I can try it on a 3kVA transformer I have for an angle
grinder. I have searched though eBay for normal US wall sockets and to
my surprise cannot find them. I've tried all sorts of search terms but
obviously have not hit the right combination, unless there is some law
which prohibits them being sold retail or something like that.
Probably me being stupid.
Looking through the parts list there is something I'd like the list's
opinion on. The diagram shows a transformer but the list says
"REGULATOR ASM, FERRORESONANT-60CPS 120VA" and a similar option for
50Hz which of course I don't have. What are these for? Might they work
at the wrong frequency? Will they be damaged or just not work? This is
part of a 48v DC supply. Should I build a simple 48V supply myself or
even see what I can find in my verifier spares?
There are several articles on the 'Web describing how to replace the
battery in a DS1287 and similar Dallas/Maxim chips; it's really not
very difficult (even I have done a few), doesn't require getting a (possibly
also about to die) replacement, and makes future replacement of the
battery a snap. Also avoids problems with added height due to a socket.
See:
http://www.mcamafia.de/mcapage0/dsrework.htm
for an example.
It won't fix Y2K though ;-)
See:
http://www.maxim-ic.com/appnotes.cfm/an_pk/503
Worst case, if you do destroy it you can still do the socketed replacement
thing.

The BIOS battery in a Compaq SLT/286 is embedded inside the Dallas
DS1287 clock module. The battery itself is +3V, but you replace the
entire module, chip _and_ battery in one go. This is entirely unlike
"modern" PCs where you have a Lithium coin cell (CR2032, typically)
accessible and easy to replace.
It's easy to find discussions of this particular machine. Here's one...
<http://www.vintage-computer.com/vcforum/showthread.php?p=91535>
Physically, the DS1287 is located in the middle of the board, under
the battery tray, but you have to dismantle the entire machine to get
to it. Also, it's soldered in place. To make it harder, there's not
enough vertical clearance to install a socket. I installed a
low-profile socket in mine, but had to nibble a hole in the battery
tray to make room for the replacement Dallas clock.
It is not a trivial procedure to replace the DS1287 in a Compaq
SLT/286, certainly not compared to popping a coin cell out and in.

We've got a chap looking for an ID on the following - anyone got any ideas?

Photo dated May 27th 1947, apparently (so speculation so far is some form of
relay-based controller rather than a computer, but that's merely a guess)

Hi! Does anyone know where to get those rows of individual machine pins for
wire wrapping?
I have searched for them but no luck so far. I know they come in bags of
rows of 50 pins or so as I've seen them but can't find who sells them.
Alternatively, break away wire wrap machine pin SIP sockets would also work.
Thanks and have a nice day!
