When I was a young’n there was a mail-order company called Edmund Scientific Corporation.

You mean this one?

If I had to to it again, I would build a proper frame for it. Probably use it for something more advanced, maybe a small steam generator/engine.

Someone must have manufactured these as subcontractor to large screen tube TVs. Why can't they be still available somewhere?

It is the perfect tool for a cheap power solar still quickly to produce large quantities of safe drinking water.

Limited only by human imagination.

All you need is a fresnel lens. Can buy one at Office Depot:

this guy better watch it or ATF will kick down his door looking for him and his unregistered destructive devices.

I learned COBAL in college and Asembler language. Used a bit of COBAL in my early carer but got in with a bunch of UNIX guys and been doing that for over 20 years now.

Thanks.

Do they also carry the Tesla Death Ray?

We still have a course in FORTRAN here.

Here where?

I remember in the late 50s our engineering firm sent calculations off to be processed at Stanford Research to be processed at night on one of their IBMs. A 360, I think.

As part of the available service, we could write our own structural and geodetic programs in FORTRAN.

I would love to try that again with modern PC processors which would embarrass those old multi-million dollar machines.

real rednecks never say “hold muh beer..” we do it with the beer still in our hand.

Or held in our teeth!

You got that right!
An assault lens, if I ever saw one.

“Must find old 50” tv...”

I’ve got one in my living. Damned monstrosity WON’T die! 5000.00 in 1994. Apparently it wasn’t a ripoff.

“I would love to try that again with modern PC processors which would embarrass those old multi-million dollar machines. “

I recompiled a FORTRAN program for my PC (286) and it ran so fast I did not believe it. It was done in the time it normally took for the network to query the VAX 725 and back.

Well, I checked the results; they were identical. I never went back.

BALONEY!!!

[Great magnets]

You want some powerful magnets, just take apart an old hard drive and take out the magnets. Put one of those on your fridge and you almost need a clawhammer to get it off.

That’s some serious longevity. I’d say it wasn’t a ripoff.
