I still have a TEK 475A (with the DMM4 on top) and a TEK 11043A
mainframe scope.
The 475A is rock solid and is one of the best analog triggering scopes
ever made. The 11403A goes all the way up to 3GHz but, tbh, is was a
difficult to use touch screen scope. I still use both of them
Accordimg to certain individuals on this list, going back a few years,
electronics/computers can be damaged due to an electrical storm, presumably
very intense activity, even while off. Go look through the archives.
I knew people back in the 80s that said they could "torque" certain
Well, if you're after an EMP-tolerant oscilloscope, there's always the
mirror-galvanometer + rotating mirror variety. Precedes the development
of the CRT by quite a bit. Runs fine with clockwork.
It's amazing what can be done with simple electrics and mechanics.
Anyone remember using the

Yes, as will most contemporary electronics, even without elaborate
protection.
The amount of current induced in a device by EMP is a function of the

Hi Bill,
I have not read the history of Intel lately but here are articles I have
read starting with:
https://www.techspot.com/article/1397-intel-8008-microprocessor/
Over the course of the last month or so this is what I’ve read:
I used to have a Tek 453(?) that was really nice. I sold it when I got a Tek
7201(?) 1Ghz model. I recently sold it. I hated getting rid of it but it was
big enough to be used as a small desk and weighed more than my back could
handle any more. I still have a 561A that I've been meaning to

wrapped in layers of aluminum foil inside a small ammo box inside a larger ammo
box?
In an ammo box buried in copper pennies? Back when they were taking copper out
of pennies, I stocked up on the all

Except for the EMP. It'll theoretically render such devices nice looking,
well-built scrap.

I’ve read with great interest, over the past short while, a few interesting
articles on the history of the Intel 8008(officially released in April
1972) as it was the forerunner of what was to become the personal computer
industry. And done with less than 4000 transistors. I saw one at a computer
Hi all, I am completely ignorant when it comes to VMS licensing and how it
works (or worked).
I purchased a MicroVAX that is running VMS V5.3. Do I need to worry about it
ceasing to work at some point?
I don’t have any paperwork for the license, just a running machine.
What should I know about
