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?
