If you had the opportunity to write a classic computer related phrase
(or whatever will work) on a 2.25" diameter button, what would you like
to wear?
Of course some of the classics are:
////////////
BYTE ME!
////////////
DANCE
ALGORITHM 1.0
0A ASL ;SHIFT TO
THE LEFT!
4A LSR ;SHIFT TO
THE RIGHT!
48 PHA ;PUSH A!
68 PLA ;PULL A!
EA NOP ;BYTE!
EA NOP ;BYTE!
EA NOP ;BYTE!

(this one is a bit harsh, I'd prefer to use a different phrase)
//////////////

reason: I have a bag of old buttons I am relabling (sticking new labels
over the previous 1996 dated event designs) to give away at VCF 5.0,
besides the Commodore related ones (of course) and those above, I am
open to do other designs (I have already did a nice "I'd rather be
playing Spacewar" in button form). Just let me know, I have about
60-100 buttons I'm doing. (color and photos are doable, fonts too if I
have em.)

Open to the public on Fridays and sometimes Saturday:

Unless you're there at 7:50 AM on Friday, you won't get the
stuff that anone else might want.

I find myself in Madison WI for the next couple of days...
I recall someone mentioned the UW surplus shop as a good spot for classic
hardware...does anyone know its hours and location?

Given that the tolerance on electrolytics is often -20% +50%, I'd say the
22000?F should be fine. It's a reservoir/smoothing capacitor, so 33000?F
would also be good.

The others won't fail the way electrolytics do. As to the electrolytics,
many are probably OK and I'd not replace any apart than the ones I thought
were faulty. I might replace a whole batch in an old switch-mode PSU if
one was failing, because experience suggests that in tightly-packed units,
with several caps clustered together, more than one starts to go at around
the same time. Especially in SMPSUs that get hot.

One of those little round BIB cleaners? Great!

I supect local naming conventions for Isopropanol Alcohol.

Methanol is to be avoided, very flamable.

Yes.

Yes!!! Glues vary is solvency and solvents used so any one can
be problmatic.
MOST ALL are FLAMABLE.
Many of the older (gray silicon plastic packages) are more liable to
damage
by agressive solvents. Water is the safest, generally.

Should not if done with care.

NO! the pressure could beak those fragile wires.

Likely ok, with great care to avoid putting mechanical forces on the
core wires.

NO.. NO, NOOOOOOOO! canned air can be high pressure and Blowdryer
is a risk for FIRE. Isopropanol is flammable and both the motor(brushes)
and the heater are risk for sparks.
Cleaning core is difficult due to the great fragility and the problem
that
the solder points for the wires can be weaker than the wire due to
corrosion {possible environmental} and the stripping methods that may
have been used to remove the insulating coating. More often than not
the actual core mat is a cleaner location with plastic covers and the
like. The latter suggests disassembly of the core stack to observe
the condition and cleanliness as compared to the external boards
(drivers and sense amps).
Use care.

IBM was a latecomer in the alliance. At the time this was agreed,
DEC's Alpha outclocked all other mass-production cpus, but Intel
was outspending everyone in production technology research.
IA64 is the result of a chain of decisions that started a long
time ago.

Build the ZX81 kit! I've done three of them and they're easy and fun (if
your soldering skills are good).
If you're planning on using the ZX81, remember: you don't *have* to build
it into its case (with its "unique" keyboard) and you can also leave the RF
modulator out and make an easy modification to provide high-quality video
to a modern TV with composite video in. It's also easy to increase the
onboard RAM from 1KB to 32KB. You wind up with a pretty fair Z80 system
with a decent BASIC, crisp video, access to the Z80 via the expansion port,
and adequate memory.
Let us know what you do!

By time it's available for hobbiests maybe. Most of the stable products
were ahead
of the pack, they had to be the pack was hungry and chasing!
Lessee, Alpha, remember the 64 bit cpu that was what 10 years ahead of
Itainium
and the slow parts were maybe 2 times the speed of the fastest intel part
running intel
emulation.
DLT quantums flagship tape backup... formally a DEC patent and was the
TK50
back in the mid 80s when the competition was DC600 and 9080 carts.
The RZ series of 3.5" drives were connor electonics but the HDA were DEC
technology and design. Those SCSI drives were right on the front edge of
SCSI standards that were still emerging. Oh and they were fast as well
for their time.
Beware the comment that sounds like allways and never, rarely are things
really that way.
DEC was one of the leaders, while they were selling PDP-8s in the
form of DECmates and PDP-11s to people that didnt want or need VAXen.
Even those "old" systems were sometimes more modern than the PCs
of the moment. If anything else they were more likely to be to be found
in use or at least working in the early 21st century.
