I have a working "no-name" laptop (it doesn't seem to have a brand
name, just "Notebook Computer" on the label) made around 1991.
It's a 486-66 with a whopping 8Mb RAM, 540 Mb hard drive, color
LCD screen, and a PCMCIA 33.6k modem card. It's running Win95
(albeit slowly). It works just fine for email and word processing
but bogs down trying to run Web browsers (not sure if more RAM can
be added or not). The battery pack won't hold a charge for more
than a day or so, and the CMOS battery is dead, but aside from
that everything works fine. I just bought a more modern Dell used
laptop so I no longer need this "classic" ;)
Is anyone interested in purchasing it cheap? Make me an offer...
thanks
Charles
Just a quickie folks,
Does anyone have the power cable pinouts for the Osborne 1 motherboard? Got
one here from Kevan that doesn't boot at all - consistent garbage on the
nice'n'bright screen. Before I start further messing with the beast I want
to make sure it's getting enough juice. Suppose I can always check the CPU
and RAM chips for +5V couldn't I - it's been powered up in this condition in
the past so I'm not going to do any more damage to it :)
Got to dig out my hot glue gun too - in their infinite wisdom they've glued
the mountings for one of the daughterboards onto the motherboard :-/
Cheers!

Finally cleaning out around the house, started with the PeeCee junk. It's in
a pile next to the trash, let me know if anyone needs any of this, quick, I
want it gone! Cost = Shipping (shipping included) :)
All these are ide hard drives, most all western digital caviars, a couple
quantum & fuji
five 2.0gb
two 2.1gb
three 2.5gb
five 1.6gb
(figured some might want these for SBC6120 projects, probably 95% of these
drives work, one or two may be bad)
CTS 212AH modem - didn't know if this might be old enough to be collectable
Mitsumi CD with non-ide interface card
Several quad speed ide cd's
a 5.25 1.2mb floppy drive
Many misc cards that go in 486 type systems - serial/parallel I/O cards,
sound cards, modems, etc.

What you need is the "UDA50 Prograsmmer's Doc. Kit", QP-905-GZ. It's
not really UDA50-specific; I last used it to figure out what was wrong
with the DU: driver in RT-11 5.01, such that it wouldn't work with an
RQDX3 (DEC didn't follow their own protocol properly, was the answer,
and the bug happened to get past an RQDX1 but not some other
controllers).
Mine is labelled "First Edition April 1982" and consists of:
AA-L619A-TK Ver.1.2 MSCP Basic Disk Functions Manual (approx 170pp)
AA-L620A-TK Storage System Diagnostics and Utility Protocol
( 46pp)
AA-L621A-TK Storage System Unibus Port Description (58pp)
The first deals with MSCP itself; gives an overview, a bit about the
comms side of it, algorithms, message formats, and a subset of commands
for disks. The second deals with DUP, which is what's used for
diagnostics and formatting. The last is about the port driver, which
you can think of as the layer under the class driver (MSCP/DUP).
Has the MSCP patent expired, or do you still need to license it?
And can you get copies from DEC/Compaq/HP, and if not, do they come
under the permission DEC gave to make copies?

Any thought been given to porting PUTR to FreeBSD/Linux/Unix??? Was hoping
to use it but really don't want to install a dos partition on my Unix PC.
Other solutions out there?

So, is there a document anywhere that explains the 'programmatic'
interface to MSCP-type controllers (or for any particular controllers)?
And I'm looking for disk MSCP not TMSCP. Basically, I'd like something
that explains the registers, command packets, etc. for hardware like a
RQDX3 or KDA50 or...
Any help is greatly appreciated. I tried with little luck on google
last night to find thist kind of stuff.

>From The Register: "Intel and HP find oldest working PC"
(http://www.theregister.com/content/67/34933.html)
"Dutch company PHI DATA yesterday received a € 18,000 prize from Intel, HP
and Dutch IT weekly Computable for still owning and operating a vintage IBM
5160 (Intel 8088) computer from 1983. PHI Data uses the IBM to test matrix
printers. It is now officialy the oldest obsolete-yet-active PC in the Low
Countries."

"When Dell ran a contest in the USA back in 1999 for the oldest
small-business PC still in use, the winner was the Altair 8800b. Still
running a 1960 Digital PDP-1 to do your maths? Let us know."
I suspect that a number on this list can do better.
