Call me odd, but my absolute, top favorite computer is my MicroVAX in a
BA123 chassis. If the house were burning, that would be the one computer I
would try to retrieve. Sadly, last night, the daughter snapped the corner
off the louvers on the top left of the chassis. Unless some kind sole has a
replacement part, I plan on gluing the pieces back on. My question is,
cyanoacrylate or epoxy?

Neither. Epoxies won't stick well to plastic and cyanoacrylate type
"glues" (superglue, crazyglue, etc) will make an extremely brittle joint
and will make future repairs nearly impossible. If it is ABS plastic, use
dichloromethane (methylene chloride) to solvent weld it back together.
Align the parts and allow the solvent to get into the joint via capillary
action. Be careful not to push the parts together hard enough to squeeze
plastic out of the joint because that will make the joint brittle too.

Agreed on that one. Two days ago, I repaired the broken-off "tang" on
a bezel to a 3.5" drive. No more than about 3mm wide and 2mm thick,
solvent cement did a perfect job in restoring the part. I used a
hobby-variety brand called "Tenax 7.R'. Dichloromethane is also
referred to as "methyl chloride". Done well, the repair is invisible
and will not show discoloration with age.

In any case, it seems Tenax 7R is discontinued, which is a
shame since I have some Mac case parts which broke recently.

Ambroid Pro-Weld is another option that contains dichloromethane,
although in my experience, it's not quite as efficacious as Tenax. But
it does seem to be readily available.

Is it? I must admit I never realy used the traditional names, but I
thought methyl chloride was CH_3.Cl and methylene chloride ==
dichloromethane == CH_2.Cl_2
If you have space, and an 'invisible side' to the repair (say the inside
of the case) you can make it even stringer ny cutting a piece of cototn
fablric (e.g. an old shirt) to cover the repari, putting it on, and
'painting' it lberally with the solvemt. Oce the plastic has softened,
force the fabric into it. Let hte solvent evaporate, and it should be
good as new.
One warning,.. If the plastic hs becoem weak/brittle with age (as many
do), this rerpair will not reverse that. So the part may well fial agian,
in a different place, perhaps, before long.

With SOME plastics, (usual disclaimers),
you can get some further strength by taking a soldering iron and run it
along the glued seam, melting the edges together.

If there is an invisible side to the brittle part, gluing (choose your
adhesive according to the substrate) some fiberglass cloth on the
invisible side can often make what appears to be an un-salvageable item
workable. If there are missing pieces, don't forget your friend, auto
body filler (AKA "Bondo") and paint.

And these days, it is getting hard to find any non-molded mains plugs.
Over here there's ridiculous law that says that all mains-powered stuff
must come with a fitted plug (I can't rememebr if it has to be a 13A
BS1363 plug,but prctically it always is). This means most things come
with moulded plugs. COmplete wit inadequate cable strain releif,
un-inspectable connetions nad other horrors. Which means I normally cut
off said plug and fit a re-wirable one.
Such plugs are therefore not as common as theu once were, but they're not
difficult to obtain.
As for the power cables, I have forgotten
Most IEC cables onver here are moutded at both ends, but rewirable IEC
scokets (adnd plugs) are easily avaialble if you want them.

PROBABLY a monitor adapter of some sort.
Somebody clueless may have looked at the DE9 and automatically labelled it
as "RS232" (as a misuse, meaning serial)
My assumption, actually, is that it's a custom peripheral
adaptor for the projector. The presence of ADB and PS/2
ports would make me guess that it's so you can attach a
mouse (some projectors used it for their config screens,
others let you control the host machine's cursor through
the remote, which would indicate the other direction).
The DE9 is probably for a serial mouse (which I recall
being pretty popular before PS/2 was ubiquitous).

Serial mice normally mated to a DE9M!
(suitable for connecting the projector to serial of host computer
for control of host computer, not for attaching mouse to projector)
But the ORIGINAL Microsoft "Bus Mouse" (green-eyed mouse with
it's own ISA card) mated to a DE9F on the mouse card. That,
of course, resulted in people plugging the mouse into CGA and MDA
and plugging the monitor into the mouse card. (YES, college
employees did that A LOT)
Because of the potential for hardware damage, the "bus mouse"
switched to a mini-DIN connector, and the mice that mate with
DE9F are R at RE, and long gone before this device.
But, we are opining over something inconsequential.
Pay postage, and YOU CAN HAVE IT!
(It is a molded (not moldy) cable, so pinout changes
for any other use are inconvenient.)

I appreciate the offer, but I have overflowing cable bins

question is how do you fix (and fix good) the daughter for breaking the puter to begin
with. Does she need glasses?
My mother used to tie heavy loads around a particularly pernicious cat's neck to keep
her from killing all the birds. To impede her ability to moved fast enough to do any
damage. She's from Yugoslavia. The neighbors would remove the rocks when she came
around. From the cat's head, not my mother's.
Does Dad need fixin' for putting puter where daughter can abuse it? Years ago my
friend set up his Tandy 2000 w/the vertical floor standing fixture. She, ~ 1 year old,
thought graham crackers would work as well in the floppy drive as disks would. Live and
learn.
?Just a few things to think about.

There is an old tale, of a brazilian guy who sold an old 486 for another
brazilian guy, tested the machine in front of him...and being called at
night with a complaint of "I cannot pull the CD-ROM disc from the machine".
And the CD-ROM disc was inserted into the 5 1/4 floppy drive...

A bit more recently, it was not uncommon to find CD-ROMs pushed in
between the drives (or blanking plates).
In the days of the Mac II, etc. the cases were designed ot take 2 floppy
drives, but only one was fitted as standard. There was a blacnking plte
fited bekind the slot for the second disk, but it was inadequatley fixed
and often fell out. At which point users posted their disks int othe slot
whereupon they fell down inside the machine. I rememebr repairing a Mac
IIfx and extracting half a dozen floppies from it.

C: It was effectual in causing dad to get his puter off the floor. In that sense it
worked.
??? I doubt such a youngin is capable of arriving at your conclusion logically. If she was
of the habit of leaving her graham crackers in the drive, then coming back and eating them
later, perhaps then at some point she might try to dine on floppy media. A long shot, only
likely in the even the computer was not used for a length of time. Dad would certainly
have heard a particularly nasty sound once he turned it on, and would have extracted it.
?Perhaps there's a profound discovery herein. Perhaps graham crackers might be the
ideal media everyone has been searching for.
?I sure hope you all in Brazil don't feed your chillinz old floppy disks when supplies
get low (A JOKE). We who were born in bigger cities have, or at least I have, dined quite
regularly on plaster chips (and slabs!) in our youths. But the texture is far to be
desired over floppy platters.

I had a similar problem with an old case from the 70's so I went to the
local hobby shop first (as I suspect that a hardware store would sell me
something more general) - after all hobby shops are the plastic experts -
they sold me this. Fantastic and has heaps of other uses - I even used it to
repair the broken support on a monitor - it was cast aluminium.
