What people fail to realize is that plastics for the most part are not
hermetic! Over time most plastics absorb water and water will react
with aluminum to ozidize it. Same for plastic encapsulated chips!!!
It's that permeability of plastics that cause anything encapsulated
in them to degrade ofver time unless the material is passivated or
chemically stable (gold, platinum...). Heat accelerates the reactions.

I think there are plenty of mechanisms, not all well understood.
Example: Thermal cycling (repeated warming and cooling) causes
mechanical stresses. These grow microscopic cracks at imperfections /
scratches / impurities in the plastic until there is a path for
corroding chemicals (like water) to get in at the aluminium.
Some CDs now use a gold layer instead of an aluminium one. I don't know
how much longer these last.
The above mechanism can be combated by keeping the discs in a
temperature-controlled environment (a lake I would have thought would
not be too bad for that but obviously it was...) - but mechanical
stresses still occur when spinning up and down.
Just my 2d worth.

How about something in a cartridge format? Alot of Video game carts these
days are topping 8mb.

Just before Christmas I found the following cassette software in ziplock
bags with the manual:
Extended Basic by Processor Technologies for the SOL-20

a terminal program (I forget the name) by Dynasty Computer for the=

I want to approach a company about getting permission to copy their
manuals and system software to distribute to other collectors.
I think that it would go smoother if I already had a contract drawn up
before hand. A generic agreement.
Does anyone have experience with this? Or are there any Lawyer/Collectors
out there? I'm looking for real experience.
If a document like this doesn't exist, it should. We need to do all
can towards tracking down who owns the rights to the software
that keeps our machines running and getting their permission to
copy it for others.

Fun Fact:
The PMC101 "MicroMate" CP/M 3.0 System disk comes with a
utility called CONVERT which allows the user to configure any
of the floppy drives attached to the system (up to 4) to read and
write disks of a number of different CP/M formats. The disks
must already be formated. This utility makes it easy to transfer
files between these formats:

Hey guess what, very odd. If you have the cart's in and you boot to a normal
plain old DOS disk, just type 123 and it Loads!! YES! Don't know how the
heck it does it, but it does work.

It occurs to me that 100-200 years ago we did not have certain modern
conveniences, like the heavy tractors with big metal spiky rollers
and/or wheels that I've seen in use at landfills. I'd guess the
object is to flatten the refuse layer out by crushing it.

Apologies to all.
On 1/3/98 at 12:05pm I attempted to send a private note to
Ward Donald Griffiths III, concerning his signature......
but it was posted publicly instead.
It was an accident. I believe that any group needs to limit
the discussion pretty strictly to the stated topic only, as
I've seen how it can get too far afield on other groups.
For the record, I hit the "reply to author" button, & it
replied to everybody. I'll try my best to be more careful
in the future.
Most of the people in the group simply ignored it, possibly
the most appropriate thing to do. About six (not many out of
200 total) reminded me that the subject was classic computers,
with varying degrees of civility -- nuff sed. The absolute
standout First Prize response was from Uncle Roger, with such
a bizzare comment that I am left speechless -- thanx Unc -- I
will be driving down to SF when you least expect it, & deliver
your new big heavy bible up side yo head. Just kidding.

I've got a line on a Tektronix 6132 workstations, and I'm wondering what
exactly it is. According to the current owner it runs Berkeley UNIX ver
4.2 with some 4.3 extensions. Apparently it's been sitting in a closet
unused for the last 8 years, so who knows if it's working. He also
referred to it as a UTek workstation.
I didn't even know Tek made any computers, and web searches bring up zilch.
