The unit that seems most commonly available is branded "Ion" and
comes with a USB link built in.. specs for it sound like a fairly
good "consumer" grade turntable. There is also a device available
that takes a turntable preamp signal and converts it to digital audio
on a USB link. Thus allowing those of us with audiophile grade
units to continue using them....

Synertek made character generator chips (really mask ROM)
and LSI video scan generators that commonly appeared
in 70's devices. Doesn't help narrow down what was
in that terminal, but the point is they did a lot of stuff
for that market (including CPU's in the first microprocessor
terminals).
Didn't somebody from that era at Synertek talk at VCF
East last year?

I hate to re-open a common thread, but I've tried both Goo-Gone and a
hair drier to remove old labels from diskettes, and it hasn't gone well:
Hair drier: I have to heat the disk so much that I warp the jacket if
I'm not careful. Way too much work (5+ minutes of low heat) per disk.
Goo-Gone: doesn't appear to penetrate the paper of the label! I mean,
it does, but I have to apply it twice (both times with my finger,
otherwise the cloth soaks up too much)... and only then does it
marginally work. But worse, what's left over is some petroleum-ish film
that I can't remove, even with soap and water. Check the following photo:
http://www.oldskool.org/misc/residue.jpg
So I wonder how well a new label will stick with that film on it...
So, are there any other alternatives? Or am I incredibly inept and
missing a step or botching a procedure?

This is a semi-automatic unit.
A from-to list is generated on a computer with lengths
and the unit moves to the start-end points. The manual
wire-wrap gun sits in the slot that the table moves to.
Don't see the wire bins.. Normally a light would appear
next to the bin to pull the wire from.

I've had one CD-R shatter and the drive was indeed unusable after that.
I tried to repair it, but after an hour of clearing bits out and putting
the thing back together, testing, dismantling, rinse, lather, repeat
I decided it wasn't worth the hassle. I still have it in case I
magically
run out of CD drives in some far distant future ...

One of the last projects we did at Philips US, was a study to see how fast
we could spin the disk before it shattered. A friend of mine, a mechanical
engineer, did the testing. He had a blast. It was like a mini version of
Mythbusters. Even had the high speed television camera.
To accelerate the process he would often nick or chip the edge of the inner
hole. When they split - literally - it was right through the front door of
the drive. He finally got his own lab so the rest of us would feel safer.
But what a fun job he had! He loved his work.

CDs were being developed for more than a decade before they became
commercial products. When I worked at Philips in the Optical Storage Group,
I made several trips to the Philips labs in Eindhoven. There, Philips has
displays of many of the original CD's and players, a few still working. It
also gave me a chance to talk to some of the original engineers, at least
the few who haven't retired by now.
Going commercial with the new technology was a hell of a battle for Philips
and later Sony. It was not instantly embraced.

Hi
The one I'm looking for was made at a similar time but about
a year later was made by Diehl and sold here in the US by
SCM. It was also transistors and it used two delay lines.
It booted from a metal tape with two rows of holes. I assume
clock and data.
It had a connector that was suppose to be able to read punch
cards. It could store a program of about 60 steps.
I used one of these years ago but I don't recall if it had
conditional flow. I think most people would consider conditional
flow to be the defining line between a calculator and a
computer. At least from the users point of view.
No one would dispute that the guts of these calculators were
computers.

Yeah, me three.
I'd like to know what the difference is between
a writable (write/rewrite) CD/DVD and
ordinary ones.
How do you "write-protect" a CD/DVD??
This would be useful knowledge, especially
when I get a DVD-recorder (sometime this

Yeah, that looks about right. So why were the

While the subject of *removing* diskette labels has cropped up before
(for example,
http://www.classiccmp.org/pipermail/cctech/2002-October/003294.html), I
don't think I've seen any discussion on where to obtain *new* ones. I'm
setting up a PCjr system for a friend and would like to prepare a nice
set of software for him, but I have no labels. A while ago, I tried
generic Avery mailing labels that I thought would work, but after a few
months the adhesive dried up and they all fell off. Any suggestions?
Newly-created sources preferred; I tried some old labels in "new old
stock" I have but after 20 years they're dead on arrival; they don't
stick as soon as you pull them off their backing.
On a related note, what's the best adhesive to re-apply labels that have
fallen off? I have some commercial software (games, etc.) where the
label is historically relevant and I'd like to re-attach it.

Interesting. Most people seem to say nice things about

machine's short comings from your perspective?
My biggest annoyance is being unable to determine what
state the softswitches are in at any given time. I
also understand the cassette interface left something
to be desired (I've always enjoyed the luxury of
floppies). Beyond that, the machine just oozes quirky

I've got a CBM 8032 that powers up "fine", but the screen is filled with "!" on
every other character position. When some letters are repeated, they can change,
i.e. "nnnn" becomes "onon" which seems like (without checking the ASCII charts)
that the "n" and "!" are ORed to become the "o". Anyone have any ideas what the
problem might be? Most of the schematics I have are buried someplace, so I
thought I would start here.

The volatility of the preservation medium, future ability to recover
a document in obscure formats, and the sheer volume of digital content
vs saved paper.
Is everything you're 'backing up' checksummed? How do you KNOW
it hasn't already been corrupted?

This is a huge issue amongst archivists.
"Personal papers" aren't on paper any more, if they exist
at all they are directories full of email.
On the CBM 8032, I downloaded the schematics from
http://www.zimmers.net/anonftp/pub/cbm/pet/, and that helped a lot. Tony's
comment about odd and even made things start to make sense. My only question
there was did the count start at zero or one :). It appears that the count does
start at zero (even). I have some doubts about the schematics since D3 is the
one line (on a clear screen) that seems to be always high, and that doesn't
correspond to bit 0 always on. BUT it appears that the 4114 at C4 is bad, and
I'll scope it out before removing it and putting in a socket.
BTW, what is the difference (if any) between the 8032 with the wide plastic
label, and the 8032 with the two plastic logos? The one on the right says "CMB
Model 8032" and the one of the left says "Commodore". I have both models, but
this one is the one with the two plastic logos.
And many thanks for the help on copying a floppy on the Mac 128. That worked
like a champ. I did find that putting an icon into the trash didn't eject the
disk for some reason. However the flower E worked great.
Thanks!
I have a Mac 128 and I want to duplicate the system disk. Probably a stupid
question, but how do you make a copy of a disk on that computer (single internal
disk drive.) Needless to say, I am not a Mac person. Thanks!

I sent a longer email to Al off-list, but I wanted to let the rest of you
know about something the company I work for (Kristine Fallon Associates) is
doing. We did a study for the Art Institute of Chicago about how their
Department of Architecture and Design could collect and preserve the
"digital design data" (CAD files, images, Poiwerpoints, etc.) that
architects are using more and more. Our report is online at
http://www.artic.edu/aic/collections/dept_architecture/ddd.html. We are now
just about finished creating a working prototype archival system. I'm
programming a Web client for entering the metadata and a programmer for the
AIC is doing the back end. We are using the DSpace archive software
(developed by MIT and HP) as the storage mechanism.
Our approach is certainly not directly applicable to preserving software --
we suggest using PDF's as wrappers for a lot of data -- but I think the
report addresses a number of important, and common, issues.

CHM is a fairly unique institution, that is why. There are only a
handful of computer museums that are run like museums. Many "computer
museums" are just glorified users groups, informal circles of friends,
or just guys that like hoarding machines and docs.

They deal with the problem by throwing things away. There are essentially
no corporate archives of software older than a few decades. This goes back
to the discussions here a while back about companies discarding software
after a product's life ends.
One of the things I've been disturbed to discover is CHM appears to be one
of the few institutions who are attempting to archive software.
Corporate archives today are essentially all paper or microform. Trying to
deal with digital content is not a solved problem there. If you look at the
literature, they are only thinking in terms of documents, not software, with
the exception of trying to preserve some subset of software needed for document
recovery.

You could also use book tape if it's a mechanical sense system.
Very heavy, quite sticky plastic.
