Did you mean "1/2 hour south". You are still at the abandoned airfield,
right?
Could you expand a little on "Quiet, Quaint, little Quandry"?
> And I went to Mosul on Monday and Today (Wed)
In one sense, I would have preferred not knowing that. Yeah, I know there
are water runs, mail runs, etc.
There have been quite a few news articles in the last 24-36 hours. I saved
a lot of them until they got just too repetitive. I was going to say that I
stand corrected with regards to the number of soldiers killed since May 1.
I read one article iearlier today that reported numbers in the high 80's,
low 90's (can't find the article at the moment) and then another article
states 41 since May 1. I suspect I/we may be confusing combat versus
combat/accident/illness.
I am gonna close this out now and start another one. I have been
feeling overwhelmed with all this recent news. My reaction is to break
it down and deal with it in chunks.
More soon,
Dad
actually, a point of history is that the 320K disks were still
formatted for nine sectors. IBM, for some reason known only to
them, filled the ninth sector with all "IBM" if I remember correctly.
It has been 21 years since I did this, but I remembered wondering
why in the heck they didn't bother to use the ninth sector they
formatted. Maybe they were holding it close to them so they could
release an "enhancement" that boosted the capacity to 360K.

VCF Gazette
Volume 2, Issue 1
A Newsletter for the Vintage Computer Festival
July 24, 2003
The VCF Gazette begins its second volume with this extra large issue.
We've tried to stay fairly on schedule, but this issue has been
delayed a bit due to lots (and I mean LOTS) of stuff going on. So,
without further ado...
In this issue:
Yet Again, a New (Permanent?) Home for the VCF Archives
VCF 6.0
Commodore 64 Parallel Super Computer Project
Commodore 64 Prototype Up for Auction at VCF 6.0
Coming in August: The VCF Marketplace!
Planning for VCF East 2.0

Latest Additions to the VCF Archives
Yet Again, a New (Permanent?) Home for the VCF Archives
-------------------------------------------------------
Ok, so some of you might have been eagerly anticipating the planned
Open House that we were supposed to have last December, which got
delayed due to the move by the Alameda County Computer Resource
Center, the fine folks that have been hosting the Archive for the last
two years.
Well, forget everything we said in the last issue.
The VCF is proud to announce its new--and hopefully permanent--home
for the VCF Archives. We've acquired a lease on a 4,560 square foot
office/warehouse in Livermore, California. The new facility has a
grade level roll-up door, a loading dock (for the big stuff), and lots
of space to store lots of old computers.
The VCF staff has been busily packing and moving the archive from the
old facility to the new. As of this writing, most of the collection
(60 pallets worth plus an additional 20+ SUV loads) has been moved
already, with a couple more truckloads to go to finish the move. The
collection has certainly grown much larger than was realized in the
time we've been at the ACCRC.
Once the remainder of the collection is moved over, the real work
begins. It will take several months to a year to fully sort and
catalog the collection, something we've been trying to accomplish
for years now. However, this time it's different. With a new
venture (see below) and a new focus, we intend to achieve this goal
and finally establish a world class computer history research facility
for hobbyists, researchers, and the business community to utilize and
enjoy.
We'll keep you posted on our progress.
VCF 6.0
-------
Hooray! The sixth annual Vintage Computer Festival has been scheduled
for October 11th and 12th. The Computer History Museum will again be
hosting the event, but this time at their spacious new home.
Being that this is the 20th anniversary of the Commodore 64, it is
being honored as the theme computer for this year's event. We expect
to have some great Commodore 64 exhibits and, if enough people pull
together, perhaps we can finally complete the long-awaited C64
parallel supercomputer. We've also got an amazing auction being
planned: a rare Commodore 64 prototype (serial #19) will be auctioned
during the VCF weekend. See below for more information on each of
these news items.
With a larger budget and a desire to push the envelope of the VCF, we
expect this year's event to be the best and biggest yet. Help make
this year's VCF a success by contributing a talk or exhibiting your
favorite old computer.
Call For Speakers
One of the most enjoyable aspects of the VCF is the series of superb
talks we assemble year after year. We've got some excellent sessions
already lined up, but we're looking for more. Have you got an
interesting computer history topic or workshop you'd like to present
at the Vintage Computer Festival? Let us know! Send your abstracts
to <vcf(a)vintage.org>.
Exhibit at the VCF
Exhibitor's at the VCF enjoy a special status. Not only do they get
all the attention, as well as ribbons and prizes for their award-
winning exhibits, they also get to be part of the behind-the-scenes
action at the VCF. Along with the speakers, the exhibitors are the
VIPs of the VCF. Learn more about exhibiting here:
http://www.vintage.org/2003/main/exhibit.php
Buy, Sell and Trade at the VCF Marketplace
As always, one of the most exciting aspects of the VCF is the
Marketplace, where you can find a large and varied assortment of some
of the most fantastical old computer thingies anywhere. Find that odd
part you've been seeking out for your collection, then touch, smell,
even taste it if you like, before haggling out a deal. There is
simply no better place to buy and sell vintage computers than at the
VCF Marketplace. For more information on selling at VCF 6.0, please
visit:
http://www.vintage.org/2003/main/vendor.php

Commodore 64 Parallel Super Computer Project
--------------------------------------------
In 1999, the VCF envisioned connecting 64 Commodore 64 computers
together to form one massively parallel Commodore 64 Super-Computer.
The project has sputtered and stalled but the vision has never died.
So this, being the 20th anniversary of the launch of the Commodore 64,
makes it imperative that we finally deliver on this vow to do what no
normally sane group of individuals would waste their time on.
Power supplies will die, chips will burn out, and nerds will struggle
over implementation details, but do this we must! To find out about
how you can contribute to this project, please visit:
http://www.vintage.org/projects.php
Commodore 64 Prototype Up for Auction at VCF 6.0
------------------------------------------------
What's cooler than 64 Commodore 64's tied together to form a massively
parallel supercomputer? How about an original Commodore 64 prototype?
At VCF 6.0, the VCF will auction off a pre-production Commodore 64,
built in early 1982 just after the Winter CES, and harboring serial
number 19. This is perhaps the rarest of all Commodore 64 computers,
as no other prototype Commodore 64 units are known to exist.
More information about this computer will be made available in the
coming weeks, including photos and screen-shots. Auction registration
will begin a couple weeks before VCF 6.0.
Coming in August: The VCF Marketplace!
--------------------------------------
We've been hinting at it for months, nay years, but it's finally come
to fruition. The VCF Marketplace--THE place to buy, sell and trade
vintage computers on the internet--will be open for business in
August.
The VCF Marketplace provides many innovative features, including a
number of different selling methods. You can offer up an item for
sale in several formats, hold an auction in one of several different
formats, even list an item for trade, for give-away, or even for
lending! You choose the format that best fits your preferences or
needs on a per listing basis. The VCF Marketplace will be a veritable
vintage computer bazaar.
We've deployed one of the most powerful search engines on the net.
You'll be able to search on a specific make and model of computer
hardware, a specific vendor and title of software, a specific title
and author of a book, and so forth. No more will you have to wade
through dozens or even hundreds of irrelevant hits to find what you're
looking for. Also available are invaluable notification features.
You can program the service to alert you the very moment an item
you've been desperately seeking gets posted.
Take advantage of the personal inventory functions, allowing you to
manage your computer collection online and share photos and
information with other collectors (a free service!) Future phases
will include store fronts for volume sellers, realtime online pricing
guides (instantly generated from past sales data) and registry
features (track the lineage of your most prized old computers).
To celebrate our launch, the service will initially be free to all
users for the first six weeks. After that, the site is still free to
use for most sellers, with very reasonable fees for volume sellers.
A separate announcement will be sent out when the Marketplace is
officially launched. Stay tuned for further details!
Planning for VCF East 2.0
-------------------------
Knock! Knock!
<and you say, "Who's there?">
VCF!
<and you say, "VCF who?">
VCF East 2.0! That's who, silly!
That's right, the much anticipated follow-up to the first east coast
VCF in 2001 is being planned for April of 2004. You poor denizens of
the right coast vintage computer collecting scene have been starved
long enough. The economy still sucks, and you're probably still out
of a job, but we're going to forge ahead and finally fulfill our
promise to return.
Much more details are of course to come, and we've still got to nail
down a date and place, but we've got plenty of time, and we've got to
get VCF 6.0 out of the way first. But don't fret, this time we mean
it: VCF East 2.0 is coming!
Your feedback is warranted at this point. The Boston area is still
being considered as the location, but enough noise from enough people
in the same place can certainly put other locales in the running. Let
use know where YOU'D like VCF East to be. Send your comments and
suggestions to <vcf(a)vintage.org>.
VCF Producer to Speak at XGDX
-----------------------------
VCF Producer Sellam Ismail will be giving a talk on the history of
video games at the next Xtreme Game Developers Xpo. The talk will
cover the first video game system, Tennis for Two, developed at the
Brookhaven National Laboratory in 1958, plus Spacewar! (1962), the
Magnavox Odyssey (the first home video game system circa 1972) and
Nolan Bushnell's Computer Space (1970) and Pong (1972), the games
that launched the video arcade industry. The talk will include video
clips, screen shots, and even actual demonstrations with original
hardware of some of the games and systems discussed.
The Xtreme Game Developers Xpo is the premier gathering for
developers, programmers, designers and anyone with a passion for video
games. This year's event is being held September 6-7 at the Santa
Clara Convention Center in Santa Clara, California.
XGDX is open to the public and is targeted to all levels of Game
Developer, from the new game programmer to the seasoned professional.
There will be approximately 20-25 technical lecture sessions and
roundtable discussions scheduled each day. If you've attended in the
past then you know that this conference is all about people sharing a
common passion: the creation ofi video games. How will this year be
different? More sessions, more peers, more opportunities to benefit
>from the knowledge and experience of others in a select community.
What hasn't changed? The belief that providing a forum where people
in every aspect of the gaming community can gather, interact, share,
and learn, will produce extraordinary results.
To celebrate the inauguration of XGDX (formerly the XGDC), all
attendees who pre-register online prior to August 1 will receive a
$250 library of Game Development books free from Premier Press (you
must attend the event to receive your lirbary in person). For more
information, or to register online, please visit the XGDX website:

VintageTech Launches e-Cycle
----------------------------
VintageTech, the VCF's historical computing consulting firm, has
just launched a new service to serve its local community. Electronic
waste has become a major issue in California and throughout the nation
as well. Discarded computers and consumer electronics--basically
anything containing a printed circuit board--can no longer be simply
tossed in the trash due to the toxic elements teeming inside of them.
To serve the need for electronic waste recycling, VintageTech has
launched a new electronic waste recycling service called e-Cycle.
e-Cycle serves the electronic waste recycling needs of the Tri-Valley
area of California's Silicon Valley. More information can be found
on the e-Cycle website:
http://www.ecycle.info/
To find out more about electronic waste recycling in your area, your
best bet is to do a web search. Not all localities are served by
recycling facilities, and there may not even be requirements in your
area to recycle discarded electronics. But you should start getting
into the habit of finding sensible alternatives to the landfill for
your obsolete electronics because there will soon come a day when it
will be required.
Suggestions for alternatives to the landfill:
o Donate to local schools, churches, charities, or non-profits
o Donate older hardware to local community college engineering
departments for spare parts
o Give or sell your old computers to local used computer resellers
o Sell your old hardware on the Vintage Computer Marketplace ;)
o Donate your vintage computers to a local collector, or to the VCF :)
PDP-8 Replica Project
---------------------
The VCF was hired to create a replica PDP-8 for an exhibit at the
Federal Reserve Bank in Boston, Massachusetts. The replica is part of
an exhibit that shows how computer technology changed the economy.
The PDP-8, which defined the "mini-computer" class, is significant
because it made it possible for small- and medium-sized businesses to
own a computer.
The PDP-8 replica will go on display at the Bank in the next several
weeks. In the meantime, a photo gallery documenting the construction
of the replica can be found here:
http://www.vintage.org/gallery.php?grouptag=PDP-8
New VCF Donation Program
------------------------
In order to help defray the production costs of Vintage Computer
Festival events, the VCF has begun a new donation program. Donations
at various levels will be rewarded with VCF pins, t-shirts, and VIP
passes to upcoming VCF events. Give enough and you can receive a
lifetime VIP Pass to all future VCF events!
Times are tough for the typical geek today, but if you can help,
please visit the VCF donation page to learn more about this program:
http://www.vintage.org/donate.php
We greatly appreciate your support, in any form!
Latest Additions to the VCF Archives
------------------------------------
We've added some very cool artifacts to the VCF Archives in recent
months, including:
o Sphere 6800 (the "first" all-in-one microcomputer circa 1975)
o Basis 108 (German Apple ][ clone circa 1982)
o MAC-8 microprocessor trainer (circa 1978)
With any luck (and possibly with your help) we'll have the VCF
Archives sorted, organized and catalogued within a year. Find out how
you can contribute to this worthwhile project by sending an inquiry to
<vcf(a)vintage.org>.
And remember: almost everything in the VCF Archives is available for
loan to hobbyists and researchers. Let us know if you'd like to
borrow something for a project or some academic research and we'll be
happy to help you out.
That wraps it up for this issue of the VCF Gazette! Until next time...
Best regards,
Sellam Ismail

While cleaning, I ran across an old EPROM programmer for an Apple II
computer. The only label on it is "Sunshine". Searching on the 'net has
turned up nothing on this card, but some information on the PC version
of the programmer. An EPROM programmer would be a very useful thing for
some of the projects I would like to work on, but I don't have any
software or information on this card. Does anyone have the software or
manual or any information on this? Thanks!

Ok, I can enhance this info somewhat.
I used both DSD 880 -8 and -30. (with great pleasure!)
They interfaced via a 26 pin flatcable to a host Adapter, and I had both
adapters for Q-bus and Unibus. Q-bus adapter was 22-bit.
(in fact, we used a 25 pole data-switch in this flat-cable to switch this
storage-system between 2 machines, as desired)
I used this storage subsystem under RSX11-M with standard drivers, DSD provided
a utility diskette with some handouts about RSX and RT and some driver-patches
(eg for 8-meg extended RL01, or RX03) that I never used. Should have this disk
still sopmewhere. Any interest?
If it is an DSD880 for pdp11, then the emulation is RX / RL. If it is emulating
MSCP its probably the DSD 9xx series of devices.
DSD440 is a dual 8" floppy, in 5" enclosure (Half RX02-formfactor!)
and providing RX01, -02, -03 emulation for all DEC OS's of those days.
I remember there were also adapters for other architectures / busses, DSD did
not limit the 440 or 880 to DEC-machines.

Actually, the I/O page is defined as the highest 8kb (4kw) in memory. For
a 16-bit machine, that is indeed 28kw-32kw. But it is not correct for an
18-bit or 22-bit machine.
The best way to think of it is simply 8kb which is discontiguous with, and
above, the available memory. Access to it is triggered by use of '1' in
the high-order 3 places of a sixteen bit address.
Of course if you have MMGT turned on, then these bits simply select the
appropriate page, which may or may not be the I/O page.

Formerly with DEC/Compaq/HP
Anybody know anything about a DSD-880 8" floppy and hard drive unit made
by Data Systems Design? (Black rack mount box about 6" high and 28" deep.)
I found several of them today. I'm pretty certain that they came off of a
system tester or circuit board tester based on a DEC computer. The units
had a Shugart 800-1 8" SSDD floppy drive and a Quantum Q2040 8" hard drive
in them and a INTERESTING looking front panel that said "Hyper Diagnostics"
or something like that.
I bought a HUGE lot of 8" floppy disks from the same place. They almost
certainly came from the same systems. The disks contained RT-11 and RSX. I
found that some of the disks had the driver and diagnostics for the
DSD-880. Also found copies of distribution disks for RT-11 and RSX in the
same pile.

Subject: Re: dos 1.0
Reply-To: cctalk(a)classiccmp.org
Let me make this REAL clear. I've had both DOS 1.0 and 1.1 and they were
identical except for different disks and a paper sticker on the package
that said "DOS 1.1". I'm also fairly sure that there was no other mention
of hte DOs version anywhere else in the package except of the disks
themselves. I specificly checked the part number printed on the packages
and they were exactly the same. I didn't go through EVERY page in the
manual but the 20 or so pages that I checked, including the title page,
indexs, introduction, copyright, etc, were all exactly the same. I'm not
100% sure but I don't think either of them mentioned MS. I did see a LATER
DOs 1.1 package that had CHANGE pages added to it that was slightly
different. I don't remember if it had the same part number and paper
sticker or not.

There appears to be quite a bit of 1.10 specific info in the manual I
have...stuff in the apendices about double sided disks, etc. This is
the Second Edition, May 1982, for version 1.10.
I have a Columbia MS-DOS 1.25 manual also, which is quite primitive
looking compared to the IBM docs. The Columbia manual apparently was
written and printed by Microsoft, with a Columbia cover added to make it
look oem. This manual is also copyright 1982.
I am not quite intent enough to pay $$$ for a PC-DOS 1.00 manual...but
if one drops out of the sky, I'll put it on the shelf with the rest of
my almost complete PC-DOS collection.

I have a 5150 with a Davong hard drive, with an external power supply
(the 5150 63 watt ps was not quite up to the task), running PC DOS 1.10.
There was software provided by Davong with the necessary modified DOS
files to make it work. The drive is partitioned, with no directories,
ie. all the files in each drive are in the root area. The computer
boots from a special floppy disk, and goes to the a: prompt which is the
first partition on the hard drive...and c: is the floppy drive...rather
odd for a PC user, but not so odd for a Kaypro 10 user.

Well, that depends on what you're measuring, really. But most of the
benchmarks mentioned only measure processor speed (mostly, as modified
by memory/cache speed) and if you want to know how something will
perform as web server, that's not very useful. You want a benchmark
that will take into account I/O bandwidth, or more specifically, disk
access.

Yep, Madge and IBM (obviously) made ISA boards. I believe they both made PCMCIA
cards too (IBM certainly did, I still have one somewhere). My old company were
exclusively 16Mbit token-ring up until about three years ago (and crying out
for leads on spare parts back then).
Support for anything other than a Windows/DOS PC was pretty much non-existant
though and as we started using more and more Unix hardware (and the odd Mac,
and Linux on x86) on projects I ended up throwing a bit of Ethernet into the
pot, and things gradually started going that way by the time I left.

Hey guys,
I just ran across a couple of DEC RA60 (removable pack) drives
and a HSC40 controller at a local dealer. They know _nothing_
about this stuff, save that it's _heavy_.
I was able to find some docs on the controller, but nothing on
the drives. As I recently acquired a VAX6630, I am considering
latching onto the HSC40, but am vacillating on the drives...
they _are_ heavy, and the dealer has no disk packs unless,
god forbid, they are still in the drives 8-( ... I need to go
back sometime this week and open 'em up for a look-see.
Not being familiar with the RA60, and being unable to find any
docs on-line, I have no idea how to open these up... does anyone
have any experience with these critters? Can they
be opened without power (i.e. is the top door locked with a
solenoid?) I found a usenet post that indicated how to lock
the heads, but I would be greatful for any info/insights on
how to open the drives, things to watch out for when
moving 'em, what to look for to indicate damage, etc...
BTW how susceptable are they to damage if moved with the packs
in them? (I _would not_ do this myself, but I know that they
were not handled gently by the folks who sold them to the dealer...
probably dropped off the back of a U-haul or something equally
gentle. They apparently came from an unclamed storage lockup)
Also, in the overall scheme of things, are these even worth
saving? I have no idea where to get disk packs for them
(I do have some 5-platter packs from CDC, model 9877, 877 and
877-51... would these possibly work? was there some sort of
disk-pack standard?)
Normally, I would not hesitate, but my collection is starting
to get out of hand, and I have to start limiting myself...eventually ;-)

Joe, Not so. The DOS 1.0 manual has no reference to Microsoft. The first
page of the manual of DOS 1.1 states Disk Operation System, by Microsoft.
The DOS 1.0 just states Disk Operation System. The part number is not the
same either.

If you have a DOS 1.1 manual then you have a DOS 1.0 manual. I've had and
seen several DOS 1.0 and 1.1 packages and the only difference between the
manuals was that the DOS 1.1 manuals had a paper sticker on them that said
"DOS 1.1". Even the part number on them was the same.

With the exception of A PDP-6 (have only one card Pulsed BUS

there is a complete collection of PDP-10's.
Lot's of stuff, like a SA-10 IBM chanel adapter, cards, manuals,
spares, perpherials: TU77, TU78, TU45, RP07, RP20, RP06, TU70,
TU71, DN87, DN200, TU55, TU56, RH10, DF10, DC10 DS10, RM05.
And enough IO-bus, Memory-Bus, Massbus etyc cables to put it
together.
There is other related stuff like one of the original CADR's, PDP8/E,
PDP9, PDP12/LINC12..
I don't remember what hapened to "Katia", when the Stacken management
decided to destroy the PDP10's, some equipment and tools (like my 2020-
extender-card, 7-trk ITS distribution, Rp06 aligment pack) was lost.
Pices of Katia might be in the warehouse. Idea was to attach the
BBN-pager to a working KA.
As for proof, here are some pictures, as you can se it's packed, and
unless someone provides a very compelling argument, it will stay packed.

Ps: I'm not a member of the mailinglist, so please send me questions
direct.
Well, I imagine you'll get quite a few offers, but FWIW I do happen
to have a few S-100 systems, to wit, a number of Cromemcos and
a couple of Vector MZs. I do also have all the documentation for them,
system manuals and manuals for all the individual cards, as well
as the system software (CDOS and CROMIX, CP/M and Unix
wannabes) and some applications, also with manuals. Mind you,
being multi-user systems, they're not quite as simple in design
as most of the S-100/CP/M systems out there.
I don't think I have the original cards for the Vectors, as I also
populated them with Cromemco cards, but I could look; in any
case no docs.
The problem as always is the shipping; I'm located in Toronto, and
S-100 systems tend to have rather heavy linear power supplies.
A couple of other list members in my part of the world have expressed
interest and of course they will have priority as soon as I find the
time to sort it all out, and I'm assuming that shipping will probably
make it impractical for you, but if not and you don't get any better
offers, let me know and we'll see what we can work out.
Good luck,
mike

Reply-To: cctalk(a)classiccmp.org
I am interested in acquiring an S-100 CP/M system and I'm hoping that
someone here might have one that they might sell or trade to me.
I've never had an S100 type computer but I've always passively wanted one to
tinker with. I don't have a particular make or model in mind but I have a
general idea of what I'm looking for. Basically, I'm looking for one that I
won't be afraid to work on, like an Altair or some other very rare or
valuable old computer.
An example that I was thinking of was a Northstar Horizon, since it's not
rare, has floppy drives, and it follows the standard s100 bus architecture
(I think.) The Vector Graphic Vector 1 is another system that seems to be
fairly simple in design but I'm not sure how rare/expensive they are.
I don't want to spend a fortune, and I'm not looking for anything highly
collectable -just something simple and ordinary that I can work on and play
with, and repair if something breaks.
Thanks,

The IBM PC DOS 1.00 manual seems to be quite rare indeed...the 1.10

Did you check the drives opto sensor's light path to
make sure that no dust bunnies are blocking the path?
i have an osi/macom that uses the same drives and
after troubleshooting three good drives - i discovered
that the drive interface card and 1 cpu had been
pluged into the molex plug backplane backwords!
one of these days i'll have to re chip and re cap both
boards.
anyhoo, you may want to check out your controller to
insure that it is sending a head load signal.
also on those drives,there are some wire jumpers that
may need to be set and soldered.
if i remember correctly - there is two different
boards used on those drives too - one is for hard
sectored and one is for soft sectored thier may be
another for mfm vs another standard too - double check
the boards on the drive's with your orignal - your
looking for the missing or complete parts on the fm
data sep and other silk screened areas and the wire
jumper location's at the back of the card edge
connector.
just rememebered my drives were siemens fdd 100-8 e
hope this helps anyway.

I have several systems that use Shugart 800-1 SS
8" disk drives.
I've
got several defective drives plus I've been wanting
some spares. Last
week
I picked up 10 Shugart model 801 SS drives. Today I
tried to use them
on
the same systems but I can't make them work. I've set
all the jumpers
and
straps exactly the same as in the 800-1 drives but the
801s aren't
working.
The system knows the drive is there and detects the
disk being in place
and
rotating and that the drive door closed but the drive
never gets the
head
load signal. I'm using the same system, cables, power
supply, etc with
both
drives so the only difference is the drives
themselves. I've tried a
couple
of 801s and gotten exactly the same results with all
of them so I don't
think that it due to a drive failure. Anybody have any
experience with
these or have a good idea of what's wrong?

At this moment in time, the only thing I want to do is see my Jupiter Ace

This is a valid approach for things that are important... but it is FAR
more time consuming then my current method. By cutting them in half I can
load them into the sheet feeder and do the entire first half of the book
(I tell Acrobat I'm scanning dual sided pages, it scans all the first
sides, then prompts me to put them back in and scan the back sides, then
it puts them all in order for me... I repeat the process with the back
half of the book, and when I am done, everything is in order and I've had
very little user interaction with it).
So really, cutting them in half is just a huge time saver. If I do the
folding method, I have to scan them all way out of order and worry about
putting them all back into order. Certainly valid and worth the time for
things I want to not destroy. But not worth it for things that are being
thrown out right after scanning.

Since there seem to be a few people on CLASSICCMP besides me running Mac OS X, I figure the following might be of interest.
One of my chief remaining complaints with Mac OS X has been getting X-Windows to play nicely with OpenVMS and other DEC OS's. Normally I use a shell script to start up a xterm with the properly configured keyboard mappings, but that doesn't work under Mac OS X. I'm used to having a fully functional keypad for editing files, and I can't live without it. Well, I think I've finally got it about solved. Simply do the following.
Dump your existing keyboard layout (twice):
xmodmap -pke > ~/.Xmodmap
xmodmap -pke > ~/.Xmodmap.orig
Change to the following keycodes in the ~/.Xmodmap
keycode 79 = KP_F1
keycode 89 = KP_F2
keycode 83 = KP_F3
keycode 75 = KP_F4
keycode 127 = Select
Load your new .Xmodmap:
xmodmap ~/.Xmodmap
Add the following to ~/.Xdefaults
xterm*VT100.Translations: #override \
<Key>BackSpace: string(0x7f)
If you actually need the normal X-Windows keyboard layout for some reason you can get it back by doing:
xmodmap ~/.Xmodmap.orig
So far I've tested this with TOPS-20, OpenVMS, and RT-11 and it seems to be working great. I'm not sure if the function keys work right, as I don't really use them, but all the keys I use for editing do work. My only complaint is that it doesn't support double-height text, but it's a lot cheaper solution than going out and buying a commercial terminal emulator that offers full support.

I have one. It is very likely that there is a lab oriented BASIC

If there is any way to save the contents of memory before you fiddle
with trying programs, it would be a GOOD THING. I haven't touched
my machine because I don't want to destroy what may be the only copy
of that program.
I would also suggest not spinning up the disc right away.
I assume you aren't getting any documentation or external software

It's true that the I/O page always appears *to software* at *logical*
addresses 160000-177777. This is fine for the processor, which has
logic to deal with it. Nevertheless, the *hardware* addresses which
appear on the bus need to be 160000-177777, 760000-777777, or
17760000-17777777 depending on whether the system uses 16, 18, or
22-bit addressing. To make life easier, DEC provide a "Bus Bank Select
7" signal, which most I/O devices use to detect access to the I/O page.
What Jerome is referring to, however, is the DMA operation. An RXV21
or RLV11 (and some other devices) can only perform data transfers to
18-bit addresses. Data is transferred only by DMA; you can't transfer
data from the device controller, only commands and status. Most DEC
operating systems expect data transfers to be able to load/save from
data buffers at arbitrary (physical) addresses; therefore drivers in
some operating systems have the option to use a bounce buffer mapped to
low memory, for 18-bit devices. They therefore transfer the data in
two stages: under program control between the bounce buffer and the
required address, and letting the DMA transfer between bounce buffer
and actual device.

Actually, for device I/O, it doesn't matter whether
one is using 16, 18, or 22 bit addressing. The PDP-11
I/O page is defined as from 28KW-32KW, which is entirely
within the range of 16bit addressing.

As far as what to look for, hold the pack so that light
is passing through the side of it. Every surface should be completely smooth. If you see any rings, it's had the head
touch it. The heads should be white to yellowish white with a dark bar in the middle. If there are black or brown smudges on the head, they've been crashed. If they clean up smooth with 95% alcohol, they ~may~ be okay. I'd have to look, but I think good heads ohmed out at 4-6 ohms. (It's been a while since I last worked on one.)

Maybe, what exactly is it? Is it by chance an 8" drive with an HPIB
Interface?

Dual 3.5" double-sided drive with HP-IB interface.

Thanks everyone for your very helpful suggestions.Â
We had originally planned to do the transfer via serial cable but someone
suggested the hardware solution, which sounded interesting, but obviously
would require more work.
We are looking into the kermit solution. If that fails then we will be
looking at logging data displayed on the monitor.

I am interested in acquiring an S-100 CP/M system and I'm hoping that
someone here might have one that they might sell or trade to me.
I've never had an S100 type computer but I've always passively wanted one to
tinker with. I don't have a particular make or model in mind but I have a
general idea of what I'm looking for. Basically, I'm looking for one that I
won't be afraid to work on, like an Altair or some other very rare or
valuable old computer.
An example that I was thinking of was a Northstar Horizon, since it's not
rare, has floppy drives, and it follows the standard s100 bus architecture
(I think.) The Vector Graphic Vector 1 is another system that seems to be
fairly simple in design but I'm not sure how rare/expensive they are.
I don't want to spend a fortune, and I'm not looking for anything highly
collectable -just something simple and ordinary that I can work on and play
with, and repair if something breaks.
Thanks,
E
