That brings me to the question of "do you buy a new battery or a new
laptop?". My T42's batter is starting to get just a wee bit old.

If you're up for rebuilding the battery, there are lots of places that'll sell
you replacement cells; should be able to get away with half the cost or
a little more. Sometimes only one or two cells are bad, although the
rest do usually follow unless the bad ones were reverse-charged or
just duds.

Here's my latest thrift score:

Two questions:
- Does anyone know the story with the AT&T rebadging? Was it sold
this way? Internal use only? What was it used for there?
- How the @!%# do you get it out of the docking pod? I'm beginning to
think it's been bolted in somehow by AT&T.
A professor has asked me where one can find decent used laptops. That is,
he needs something close enough to the bleeding edge where he can run
current applications, but far enough away that he won't have to pay much.

Hi Chuck
I saw someone mention the NSC800. I don't think it was mentioned
that the NSC800 runs Z80 instructions but has the exact same
pins and interface as the 8085.
I don't recall if the NSC800 had the serial instructions of the 8085
but in this case, I don't think that is an issue.
It was true that the 8085 had just about as fast an execution
as the Z80, without the extra instructions of the Z80. This
was true for all but the tightest loops using some of the
special Z80 instructions. I recall when I was working at Intel,
we looked at many of the Z80 instructions and found them
to not be anything but code efficient with comparable speeds.
I have a couple NSC800s but not as separate packages. They
are in MA2000 modules.
The NSC800 also has the advanges of being CMOS. This means
lower power than either the 8085 or Z80.

3 months of fighting with a T42 and RedHat Enterprise WS 4 makes me
want to never touch a Thinkpad again - a thoroughly painful experience
(and that from someone who got Solaris 7 working perfectly on a P-133
Dell laptop).

To computer collector,
Sir,
The mini-computer I have is a B80 from Burroughs.
It was bought in 1978 and I used It until 1989.
In 1989 It was in working condition.
The measurements in inch are:
Mini-computer: W=70 D=29 H=30 ( Photo )
Disk drive cabinet: W=22 D=29 H=44 ( Photo )
Power supply: W=22 D=29 H=30 ( No Photo )
The measurements are with the wheels.
I would GIVE these 3 articles, but your organisation will have to come to get it before October 5, 2007.
Looking forward having news,

Probably - but that is not weird. Even in the old days the tape and
disk farms were bigger than the processors.

Dear Sirs:
I have an antique one line display word processor. It is an Olivetti
TES 501. I paid $9000.00 for it in the late 70's. I would like to
give it to someone in the Concord California area. Can you help me?

I am not certain how to tell which model this is.
It has square control box which sit under printer.
Weighs a LOT. This is a thermal tranfer printer.
I am putting it up. I played with it a little last
week to verify that it works. Supplies will probably
be difficult to get for it, but it does come with
some. If no one wants it, I will recycle it.
If there is interest I can give detailed listing of parts.
Several paper trays, including 11 x 17.
I live NW of Chicago, IL. Pick up is probably
preferable to shipping. It weighs a LOT.

I buy old laptops on E-Bay and refurbish them for resale, a few dozen per
year. From your description, however, you professor friend should buy new.
I just sold a couple of nice Pentium III laptops from 2002 (Toshiba 2805's),
and they went for almost $200. But in my view, they are still too old to
run most "current applications", and at $200 for those, a new laptop makes
more sense than a used one.
In July I bought a brand new Gateway MT6711 at Best Buy for $499, no
rebates, straight out deal. This is a dual core Pentium laptop with a 15"
widescreen display, a 160GB hard drive, a dual layer DVD burner and a
Gigabyte of memory, with Vista Home Premium. There are a LOT of very good
laptop deals this week. I think that the deals available for $499 to $649
are good enough to make buying an older used laptop not worthwhile in terms
of value. I don't know for sure what he had in mind price wise, but he can
get a pretty nice new machine for about $500, and anything that "will run
current applications" in a way that you would want to run them will probably
be $300-$350 or more for a used machine. A machine with no warranty and
unknown history.

I would be a good thing to save. I think RSC/RI has one as well
(W.D. would know for sure)
Also, no software has been archived for this machine, so any
surviving copies would be a good thing.

<snip>
Ummm, not really; they were slightly different lines, the B800 being
the smallest of the "real" computers (successor to the B700) with a
separate processor cabinet and somewhat more power, more
suited to running multiple terminals (although the console was
essentially a B80/L9000 with no innards).
The B80 (and later the B90) marked Burroughs' transition away from
ledger cards to disks (either 8" floppies or 14" cartridges as used on
the B800) and was essentially the successor and replacement of the
L series single-user integrated accounting computers.
The B80 and B800 were priced differently and aimed at slightly different
markets, although they did share some peripherals and the system
software (CMS, CANDE etc.)

Hello,
On internet I found a chat where you write about Lilbug.asm. Could you please help me to findinformation about it.
Many years ago I used to work with 6801L1 coming with LILbug monitor. Today I still have few pieces, but I no longer have any documentation about the monitor. Could you help me to find an user manual of the LILbug or more simply the list and syntax for the commands and addresses of the routines (like conversion Hexa-Ascii and so.).
In advance many thanks for your answer.
As luck would have it, after purchasing a repairable PS for my C64 on
eBay on Sunday, then I was given a TENEX MW705-D PS for the Commodore
128 on Monday. I'm curious, it has two power cables on it, one is
the 5-pin plug for the C128, the other is a 4-pin plug, what is the
4-pin plug for?
Zane

Couple of years ago, I paid around $350 for a refurbished P3 Thinkpad, directly from IBM.com ... even came with a warranty. I think Acer, Dell, Gateway, HP, and Lenovo all do the same thing on their web sites.

What I wrote something similar I used the word "most" as I knew there was
some CP/M software that required z80. However from a business user
perspective most of the deireable and likely used software like word
preocessors, spreadsheets and databases 8080 was just fine save for
speed and the 8085 solved that. Also the 8085 was more of a bridge
than the ultimate application cpu.

Greetings;
I'm planning on moving an Onyx rack in the next two weeks and I'm probably
going to have to be fairly agricultural with my tooling - pickup truck and
flatbed trailer, no lift gate, no lovely enclosed box.
I'm thinking that to safely transport this I'll tip it on its back and lay
it flat on some 2x4s onto the flatbed trailer, but I'd love any advice
>from listers who have moved one, or better yet, who have one and can tell
me things like - how solid is the frame (after removal of the plastic
skins)? Is it top heavy? Bottom heavy? (I'm guessing after removal of
PSUs, top heavy, but unsure)
Anything would be much appreciated.
I found the below:
http://www.futuretech.blinkenlights.nl/sgidepot/chalonyx.html
Which gives a nice picture of a unit with open doors, but it's hard to
tell how solid the frame rails are. The thing looks awfully deep to be a
standard 19" rack, so I'm guessing it's custom, but... having never seen
one...
Many thanks for your time,
JP Hindin
I've got an old VAXSERVER 3600 taking up space in my house. I really don't
know anything about it but was told it was functional from the guy I picked
it up from about a year ago. I'm looking for the highest bid from someone
that can pickup in the Seattle, WA area.
