They look like a Torx screw head turned inside out. Imagine something
between a pan head and a round head (ie slightly domed) with six small
notches in the edge. The sides are sloping/curved and they're usually
hardened, and the edges of the notches are slightly rounded off so you
can't get a grip with pliers. There's a picture at

All,
Potentially useful info for the list:
1) Stylewriter power supply uses zero-screws (or whatever you call them).
2) Stylewriter PS has a seperate fuse in the - leg of the output, and it's easy
to desolder.
The long version:
Sat down with murder in my eye to work on the power supply.

A perfect description of the three fasteners holding the case
together - as I realized once I had them out in the light of day.
Unfortunately I *got* them out in the light of day by trying to pop them
loose after heating with a soldering iron. Instead of melting the studs the
threads were threaded into, I melted the barrels of the recesses the screw
heads were in. Things Got Smelly, the case creaked apart, and the recess
barrels were left with the studs, screws still firmly in place. However, at
that point, I was able to grab the severed barrels, squeeze with pliers
until the walls of the barrel gripped the zero-screw head, and twist out
the zero-screw.
Anybody need 3 slightly used zero-screws? *I* sure as heck don't!
To put back together, I plan to find longer pan-head screws with
similar diameter and thread pitch, put around the studs plastic soda straws
long enough to reach up to the other side of the case, then put the
pan-head screws (with washers as needed) through the holes that originally
formed the tops of the recessions and through the straws into the studs.
(The soda straws are to electrically isolate the screws from whatever
voltages are flying around inside, because the recess barrels ain't gonna
do it, now being in pieces in my trash can (with extreme prejudice).)
Inside, there's a big transformer. One side has 2 leads wired to
the blades that go into the wall. The other side has 3 leads going to a
circuit board. The leads on either end go through diodes to the "+" output.
The lead in the center (marked "C.T" - let me guess - center tap?) goes
through a cylindrical glass fuse to the "-" output. There's a big capacitor
(electrolytic? Black cylinder) between "+" and "-" and a few small
(ceramic?) disk capacators scattered around.
The fuse had shuffled off its mortal coil. I mean, even *before* I
desoldered it. Which, BTW and of course, I think I did without damaging
anything.
This thing is so simple even I can almost understand it. Now I need
a 3.7 (? something like that) Amp fuse with pigtails, and a couple screws,
and who knows, maybe I'll be back in power. Definitely going to be a
web-shopping day.
Comments, 'attaboys, "enough-already-with-the-d*mn-printer"'s,
etc., all welcome.

Ok guys, I have to admit first off that I read the tags wrong on that Bell & Howell. It is -- as someone suggested -- an Apple II Plus.
Also, it doesn't have the D-shaped cut-outs after all, but rather it has vertical slits with somewhat d-shaped metal inserts in them. (Ok so I didn't look too well.. :)
I've cleaned it up, and it looks in good condition, with two exceptions:
There is a pin broken off of the power cord :/ -- I'm going to replace it.
The monitor connectors are two ethernet-looking BNC plugs (WTF!?) Can anyone tell me what's going on with these?

This may be a bit off topic, but Yahoo is having a Free Listing Day on
January 24th thus reducing their already reasonable rates :). They do
have a Vintage classification and I expect to have some "stuff" there.
Yahoo has the facilities in place to handle a large number of auctions,
and with ebay continuing its direction towards retail, collectables need
a site that *wants* them.
The Xerox 4050 is a printer controller, but appears to be some sort of
mini-computer with a Xerox logo on it; it has a floppy drive and
possibly internal hard drive. If anyone knows anything else about
these, info posted to this list would be appreciated. The thing is
waiting for pickup by a scrapper, whose truck is currently being
repaired. If you get here first, you can have it. It's about the
size and weight of a chest freezer.
Also available is an IBM PS/2 Model 80-386 micro-channel tower
machine. Includes a micro-channel token-ring network card.
Both of these items were pulled from use in the last couple of months
and should be in good working order. They are available
_for_local_pickup_only_ in Lincoln, Nebraska. Drop me a note quick if
you want either of them before they go to the big bit-bucket in the
sky!

Thats starting to sound a bit like white-coat syndrome. These computers
are not rare artifacts to be hidden away behind glass walls, only to be
touched by the neophites in white lab coats, you know. Go ahead and
experiment, heck throw the completely wrong hardware in and cause a
major short circuit! And in so doing, know that you can always get another
apple ][+ or 3 for about $5 (if not for free, heaven knows i keep getting
offered the things...)
Cmon, what could possibly be less valuable than an Apple ][+? A C64
perhaps...
>>
just because they are plentiful in /some/ places doesnt mean you should just
abuse them for fun. Around here, I havent seen any apple // items available
for years.

To all (especially those that are desirous enough of the subject items to
drive
to Hackensack, NJ),
As a participant in the Computer Rescue Squad, I received this email
(edited):
-> Osborne Executive and a Texas Instruments MicroLaser Plus
-> free to good home. Must pick up, I do not have time to ship.
-> Thanks.
-> Paul.
-> Ph.D.
I answered with a brief reply indicating that I cannot do so but surely
can locate someone who can.
Paul's reply to this was:
-> A couple of other "Computer Rescuers" have contacted me but the logistics
-> are awkward. Do you know anyone who can just stop by the house here and
-> pick up some evening?
-> Thanks.
-> Paul.
-> Ph.D.
I have Paul's email address and telephone number. If you can meet the
requirements of
Paul's reply (i.e. 1. STOP BY HOUSE, 2. PICK UP (HACKENSACK, NJ AREA))
please contact me
off-list and I will forward his contact details to you.
Sorry, but because of the SPAM issues relating to email addresses on this
list
the last thing I want to do is post someone else's email address here
without
their permission.
'til later,
