Does anyone have a working boot disk for a Sharp MZ-80B?
I went to use mine for the first time in a few months, and all of the disks
are either reporting "Not a Master" or "Read Error". Since I *know* that at
least 3 /should/ be bootable[1], there is clearly something awry with
either the disks or drives. I'm going to try my spare set of drives
tomorrow, but if that doesn't work then I'm stuck :(
TIA
[1] One of them I made myself, used it, and even labelled it "80B Boot
Disk". And that reports "Not a master" now. Grrrr. :(

I became the grateful recipient of a TI Programmer today. A buddy at
work said "here, you like calculators, right? Better than throwing it
away." Well, I said "thanks!"
Now, in looking about the internet for some info on the battery styles
for these things, I have a couple of questions that I cound't find the
answer to.
This calculator has a battery pack called BP-8 which has 2 AA ni-cads
and a small circuit in it. It connects to the calculator internally
with a connector that would also mechanically mate to a 9 volt battery.
Now I would not expect a 9 volt battery to work where 2 AA's work, but
I'm not sure. In looking at Gene's web site he says the BP-8 is also
used on the TI-30 and I see TI-30's on ebay saying that they work with 9
volt batteries.
I will replace the two AA's with new ones. That should make the BP-8
good again.
I guess the is a roundabout way of asking for some background on the
power requirements of this calculator. Unfortunately my buddy had lost
the AC adapter (apparently it was an AC-9132, thanks Gene!). So I'll be
looking for one of those. 5.7v, 240ma, and that small 2-pin connector.
Thanks for any help.

Hi --
After all the whining I've done on this list concerning virii attacking the
Windows-based PC I've been using for email, I'm pleased to announce that it's
no longer a problem.
This message was composed and mailed using the email system I've been working
on -- ZMAIL. The client-side hardware consists of a Zenith Z-100 with 1 20 MB
hard drive and 192 KB RAM, plus a 56 K modem. I really don't know what the host
machine is, except that it's running Debian Linux.
The client-side software consists of an offline email reader/writer -- ZMAILER -
-- which has many of the features you'd expect: address book, reply, forward,
import file, etc. (no sort capability yet) Additionally, there are utility
programs which concatenate the outgoing messages into a single file, break the
incoming messages out from a single file, connect to the host, and transfer the
data back and forth.
On the host side, I wrote programs to grab new incoming mail and pass it to the
client, as well as a utility to break out individual outgoing messages from a
single file and post them via SMTP.
This has been a great learning experience as I had to learn enough about
CP/M-86, Linux, SMTP, and the 2661 UART to get this system working. It also
(IMHO) is a great use of this classic old Z-100 -- actually two of them, one at
home and one at my shop.
Anyway, thanks to all of you who very kindly helped me during the course of this
project. Especially, thanks to Joe Rigdon, who gave me the Z-100s, and also to
Tony Duell, who very patiently helped me with the basics of programming the
2661.
Classic computers rule! (even at 2400 baud ;>)

I just acquired a new, unused DEC VT100 terminal. I have not plugged it
in yet, because I am a little weary about firing up a piece of 20 year
old hardware that has never been turned on before. Something tells me
that there are probably some dried up capacitors lurking in there
somewhere, just waiting to blow as soon as I flip the switch. Visual
inspection really can't tell me anything here, there won't be any burn
marks or blown caps in something that has spent it's entire life
wrapped in plastic. What areas in particular should I check? Are there
any parts that are prone to failure in these terminals? Thanks in
advance!

PS - On a similar note, does anyone know of someplace online that I can
find a VT100 keyboard? I have one here, but it's in really terrible
shape - very yellow with the name of a school written on it. It works,
save for the "Return" key that normally takes two presses to register,
but I would like to find something in a bit better shape and with all
the keys present and accounted for.

Same manufacturer but different family, and not interchangeable.

Yes, they can run at a higher clock speed. About the only place you find
them are in Atari 520s and 1024s.

Hi
I've just seen the third surge protector blow
up and this time, it almost started a real fire.
I've had two of these go up in smoke that were
in metal strips. These generally make a lot of
smoke but I think the metal spreads the heat enough
that the fire danger is small. Now, most of the
newer ones are made from plastic. The last one
that just burned, started a small fire on the back
side of a chest of drawers. Luckily, the chest
didn't stay lit. It did charcoalize one of the feet.
While these things come with a 15 amp breaker,
the MOV's fail and draw something less then what
is required to blow the breaker.
I wonder if any of the fire prevention groups are
looking into these time bombs?

Are you kidding, I don't think I've ever seen
one without a UL sticker.

This is what the metal ones do ( at least the two I've seen go ).
It was a plastic one that caused the troubles. When I've looked
in the metal ones, I've never seen a separate fuse. I don't
know what the plastic one had, it is a melted mess.

Well I managed to get a M7095 module ($25 plus shipping) for the PDP11/44 I
recently acquired and now I can connect to the console >>> prompt after
powering it on. Plus I figured out how to execute the firmware utility on
the CMD CDU-720 (anyone have docs for this board?) so it appears that the
system is fairly functional.
However, after a while I noticed that some of the modules seemed to be
running rather hot and then I noticed that one of the three fans is not
working. I pulled out the fan tray and found that I can manually spin up
the two good fans with little effort but the bad fan sticks and won't spin.
These fans are labeled Torin TA450 Model A3102-10 35VAC 75Hz. Anyone know
where a replacement fan could be obtained?
