Viewing magnetic fields with CRT monitor ...

Posted in wrong thread, sorry

Gravity block,,,I would like to respond to your message,if I may.
No response from you is necessary unless you wish,,,Having said,
THAT,,,I will continuie,,I worked with crt monitors every day for around 10 years.
So,,I am more inclined toward making the YOKE,,,that sits around the neck of the crt and keeps the color lines/pixels, coming to you STRAIGHT.
The vertical and horizontal signals are pins 13 and 14 going into
your monitor.
The vertical and horizontal frequency of a particular monitor is easy found under system.
Setting the monitor at a frequency,,,horiz and vertical,,then removing the four major wires to the yoke,,,red,blue yellow, and black,,,trust me these make for some very interesting INPUTS.

But it is better to leave the case on the monitor and access the vertical driver chip,,,the hot,,,or horizontal output transistor is,
kinda limited but the vertical chip and possible ?buffer?is something else again.
I am sure a custom Instrument FOR the Magnetics Field can be provided by hacking that old 21" in the dumpster.

Not that I plan to do it,,,,I have more on my plate than I can manage now!!!,,,,,,,i am putting it out there as a real possibility,
of a real Magnet Spectrum Instrument.You could build whatever software conditions you desired.Writing straight to video memory is as old as I am (64),,,,,,even Basic,,I like assembly,
but I am weird.
I will file it for a later days,as I kept a dozen of the big Sony, Hitachi and Mitsubishi,,,,,these are the best,,I know after 8-10 years of repairing them.
Cool days are coming here now to Central Texas,,,I am re-building my forge.
GB,,,,,,,I will go now and thoroughly enjoy your above post.
Cheers

Wow, assembly language, i haven't touched that since the 6800c on the old Ataris
