Subject: Old Computer Books - what to do?
I'm about to do a Major Purge of my library. Part of that library is a
collection of old microcomputer books (catalog not yet available -
I'll post a pointer when it becomes available), which I kept around
for historical purposes. We're talking, Apple II; the original TRS-80,
and a big basket of random Bytes and Amiga magazines. Possibly even a
Creative Computing or two.
Since I'm never going to start a proper historical computer library,
I'd like to offer these books to interested parties. Not looking for
money or even recognition* here, just space on my bookshelves and Less
Stuff to Manage.
It was suggested elsewhere that I try here. Also, ebay and half.com have
already been mentiioned as possibilities, but I'm after the shelf space
not the money.
Any ideas? And, yes, interested individuals may apply.
- Patrick Connors, lost in his own library, never to return...
*My ego claims otherwise and points out that recognition is good,
where applicable. My wallet will accept reimbursement for shipping, if
offered.

Ok, what OS does it run? It says Intel Inside, but has an ADB Mac Mouse
connected... humm... I thought Apple's only Intel based OS was an early
version of Rhapsody... and that ran on standard Intel compatible
hardware, so no ADB mouse (could be an internal build of OS X for Intel,
but that still wouldn't use an ADB mouse).
Humm... NeXTStep maybe, using a Mac mouse as a replacement... they used
ADB on some model NeXT boxes, didn't they? Color is right for a NeXT Cube.
Er.. ok, I have officially taken this too seriously.

Oops, forgot one complete system, Hans.
I also have an PDP-11/05 with PC05 and Perkin-Elmer drive.
The Perkin has a removable disk and a fixed hard disk.
I guess this is the *only* non-DEC part, but it boots
RT-11 (V.4).
cheers,

All Europeans at last :-)

Ok, Hans, I shall send you a list or document privately.
Good action this :-)
Thanks and Greetings

Hi all this is a call to all european members, or should I say
members in Europe?.
I have been invited to write a paper about the work being done
in Europe on the history of computing. I have decided to highlight
the individual collectors and the valuable work they are doing.
If you are in europe and collect/preserve computer
hardware/software/documentation I would appreciate a short
description of what you do, how big your collection is and anything
else you might like to mention.
I will probably highlight the contributions for just a few of you
but mention all of you. Please let me know if you would be willing
to be be an in depth subject which will entail an email interview.
Mention also if you would prefer to remain anonymous.
Finally, if you know of any other individuals working in the field
who are not subscribed to this list I would be interested in hearing
>from them also.
All contributors will receive a copy of the paper when it is
completed.
Regards,
-- hbp

You probably shouldn't say that, since it's wrong...
Can we keep political commentary off this list?
Especially mean-spirited partisan hate speech with no
data to back it up?
I want to hear about Classic Computers on this list.
Not someone's partisan hatred.
Thanks!

Take a look at the 12992-90001_loaderRomsApr86.pdf doc on Al's site. It has
details of the operation of the various HP 1000 loader ROMs, including
source code listings.
There is a separate ROM, p/n 12992-80007 12992E, which is specifically for
booting from the 9885 flexible disk. I'm not sure what interface is used to
the 9885 for that loader ROM.
ROM p/n 12992-80002 12992B is for MAC 7905/7920 drives, 13175A/B interface.
ROM p/n 12992-80004 12992H is for HP-IB 7920H/7925H/9895 drives, 12821A
interface.
If you remove the memory cards from the front card cage of the 1000E CPU you
should be able to see the loader ROMs and if you can read the p/n labels you
should be able to reference those back to the loader ROM doc to see exactly
what you have.
