A bit ago, I posted a request to help identify some old front-panels
that have been in my collection for about 20 years. I didn't get a
single response! With all of the wise guys (sorry - smart folks ;-)
in this group, I'm disappointed! Somebody has to recognize them!
Allison? Anyone? Anyone? (The pictures are on my web page at
http://incolor.inetnebr.com/bill_r. Just click on the "Classic
Computers" link, then "Unidentified Technological Artifacts".) Your
help would be appreciated?

HERE IN THE USA:
If you violate the NI (bell parlance for network interface) which is the
demarcation line to your home or business and damage their equipment you
will likely be at the end of both criminal and civil charges. The key
issues would be if the cause is deliberate, neglegence or accidental.
They do actively persue this as deliberate tampering with their business
as both a public safety issue and interfering with their conducting
business in an unlawful manner (mischeif, vandalism).
I would bet in Europe there are certain actions available as well.
The oddity of it all is if you fry the phone line who really looses?
Your out the use of the phone and their interface equipment is likely
protected as they have to worry about power distibution lines and
lightining getting into their stuff. The damage would be more to the user
than TPC (the phone company).

Is there anything I can do at home that will damage phone company
equipment? I suspect that 240v in a telco switch is nothing pretty.

I always did wonder. I've got a couple of old (can't remember the exact
date, but I'd say early 70's at a guess) answering machines somewhere
which make use of such plugs. I'd love to wire one of these things up to
a phone circuit if possible, I doubt that it could be done though - the
systems were badged "Ansafone" IIRC, making use of enormous reel-to-reel
tape decks and foot pedals... :)
(I suppose this could be judged almost-on-topic, if the phone system is
deemed to be some giant computer, and the technology, after all, is more
than 10 years old)

I don't know how much truth there is in those descriptions of various
boxes, but there a very frequent warnings on messing with line voltage
because of what "hackers" call "gestapo".

Couldn't they cancel your service if they felt that their station
equipment was at risk of damage?

You can order them with equivalent ease from Radio Shack, for about
$7.75. It might end up being cheaper, since RS won't charge you shipping
and handling. Of course, they might be getting it from the same source
as you.

Picked a few things this week for the museum , so pleas do not ask me about
selling them. If I ever get month off to check what all I have in storage I
will be unloading all extras. The finds: 1) Franklin ACE2100 cpu and
monitor (mono) not tested yet both were free; 2) Franklin ACE2200 cpu,
monitor (mono), keyboard, Franklin joystick, and all cables, it also was
free; 3) EXELTELII was a trade; 4) new IOMEGA cleaning kit for 8" media $1
at Goodwill; 5) OPENDOC video from Apple; 6) TG Products chip tester;
7)Super Expander cartridge for the C64 60 cents at Thrift; 8)Super Graphix
jr by XETEC for the Commodore cost $1.60; 9)IQSuperPC Trivia Blitz
cartridge A cost $1.80; 10)AppleColor RGB monitor 80 cents at thrift not
tested yet; 11)some QX-10 items for free; 12) about 15 various books.
That's been it so far I will be going out later today to the thrift's about
45 miles from my home and working my way stopping at any place looking
interesting. Keep computing John
If anyone can help this fellow out, please contact him directly.

Pins 1-50 on front, 51-100 on rear.
Pin 1, 51 +8 Volts. Leftmost from the front, front and back. Unregulated
(just filtered rectified DC from the power transformer) for the +5 volt
regulators.
(Usually very easy to trace or test)
Pin 2, +16 Volts, unregulated.
Pin 52, -16 Volts, unregulated.
In my system I put fuses in these lines. Make sure the filter capacitors
have bleeder resistors attached, so they will discharge without a load.
Otherwise you might have problems when plugging in a card later :-(.
Pin 50, 100 Ground.
There were other ground lines on later cards, which you may have to check
for when you start to mix cards,
such as pins 20, 70, which were Unprotect, Protect in the early S-100 systems.
