More Info: Mesh EMI ("Tempest") screens for the CRT of 453/454 Scopes


 

To be completely clear: I was TOLD they were for the 453 and 454. I have no
way to actually check this and now I'm wondering if anyone can verify what
the dimensions of the mesh screens are on a 453 or 454. The ones I have are
4 5/8" (11.7475cm) x 3 7/8" (9.8425cm).

I forgot to say to please include your address if you want one and send your
reply to dennis at ridesoft dot com.

I have five of the fine mesh screens that were used on the 453 and 454
scopes and possibly the 485 as well to protect from radiating EMI through
the CRT face that could be picked up by unauthorized entities and analyzed
for information.

There is no charge for the screens. $15 should cover packing, shipping
within the US, a trip to the post office, and my time. I will mail
overseas as well but I can't tell in advance what the shipping charges may
be.

If anyone needs one please let me know off list. My email is dennis at
ridesoft dot com.

One per person please.>
First five replies get them.
