Well, thanks to everyone with good suggestions, and especially thanks to Don
for providing the boot disk image, I've been able to get the kaypro 4/84 to
boot! It came up in conversation that there were later versions of teledisk,
and after some heavy web searching I found one on a page for synthesiser users
that works with my computer in a dos window, even. I guess I'll have to
register it now. For reference, it's version 2.16.
So now it's off to Oak for nifty apps, I guess. :)
I do have another question: the image on my kaypro's screen is somewhat
cockeyed. Is there an easy fix for this?

Sure. Grab the yoke on the back of the tube and twist it. Wear
_real thick_ rubber gloves. Oops. I guess I should have mentioned
that first. :-)}
Tony (among others) has given good info on tube repair in the past.
I've no idea what the current skinny on the list archive is (I'm
missing maybe three weeks since Whitson started the list, so I
haven't checked the official archive in a while -- problem is that
my message base isn't indexed or have any kind of search mechanism
except 'grep), but there's good material available there and better
material when Tony checks his mail.

New subject: CRT rebuilding Was: Re: It's ALIVE!
Upon the date 12:02 AM 2/22/99 +0000, Tony Duell said something like:
There are some folks Stateside who do rebuild television CRTs. I have not
had a need to search them out yet as my TVs in the collection either seem
to work well enough or I have no desire to get a gassy or tired CRT rebuilt
as the there is something else presently unrepairable on the chassis. (Last
count I've got around 12 or so pre-1952 TVs in the collection.)
I wonder if by now those rebuilder folks are getting into computer monitor
CRT rebuilding? Hmm, I gotta keep my eye open for rebuilders. (Bill
Donzelli: have you heard of any rebuilders? I suppose I could check with
Harry Poster and see what he does or scour ARC.)
Regards, Chris

Tony, "cockeyed" is an Americanism for kattywampus :-) :-) :-)
Or, in more standard terms, not straight, twisted, mispositioned, etc.
Tony (among others) has given good info on tube repair in the past.
Talking of which, has anyone got any hints for rebuilding defective
CRTs? It seems like some madman on this list would have a vacuum setup...

The general rule among people I know is LEAVE THE TUBE
ALONE. If you have
two units, one with a bad tube and one with bad electronics, move the
electronics, not the tube. etc etc. Handling a CRT is just too dangerous.
Generally wise advise, but probably because of the economies. Replacing a
tube (or any of the other high voltage stuff) can turn your wallet inside
out.
As far as actually handling a tube - no they really are not very
dangerous. If one makes sure to drain any high voltage points (twice for
each, at least), follow all of the other high voltage advice already given
(and probably in the FAQ), and do not drop the tube, you will be fine.
Post 1960 CRTs are actually quite tough and will sustain a great deal of
physical abuse. When they break, the neck shatters first and lets all the
air in. The days of the nasty implosions due to no safety glass are gone.

Hm. You're certain? I have this disembodied memory of seeing a box in my
parents' shed in the early '80s, with an implosion hazard warning
emblazoned on. I'm fairly sure it was the box for their old TRS-80 Model
III, but it is possible it belonged to their Zenith TV they'd just bought.
Maybe it was just a bozo-warning.

Yes, mostly. Sure, whacking the side of any CRT is foolish and will spread
bits of glass all over the place, but so will whacking a glass jug of
apple cider.
Whacking an oldie CRT like a 10BP4 - umm, just do not do it.

Now, what does the FAQ say about there being some clueful people here ? :-)
CRTs are not _that_ dangerous if you know what you are doing. I must have
handled a dozen CRTs in the last month and I am still typing with all my
fingers ;-). Sure, they can be nasty if you are careless, but that
applies to just about everything I work with.

You can not. Sydex took TeleDisk off of shareware in about 1992 IIRC.
There was too much abuse usage, I gathered.

With the power off and some time passed to let everything discharge,
loosen the clamp screws and rotate the yoke on the CRT neck. Check it,
and repeat as necessary. When it is right, tighten the clamp screws.
Please be careful, as there are very high voltages in that area that
linger for a while after shutdown.

IIRC, the license it came with said that you could use it if you sent them
money, and that you could redistribute copies of it. They can't rescind that.
They can refuse to take your money when you offer it, but that doesn't mean
that you can't use the program. However, they aren't obligated to provide
any support or updates.
Note that the license for the shareware version doesn't entitle you to run
a later non-shareware version.
That's my understanding, FWIW, but IANAL.

Jim,
