It also had a nice three color optical cable that went from system unit to CRT, with fine mesh over the front of the screen. The monitors were two man lift items. Keeping the RF gasket lined up with the screw holes was a pain if the glue on the case became weak. I worked on an office full of them when I worked in Crystal City, Va.

The Z-150 had a thick metal case that had about 50 screws that had to be removed just to get the cover off. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Webster Sent: Friday, January 30, 2015 10:01 AM To: [email protected] Subject: RE: [NTSysADM] An Airgap Won t Secure Your Compute r Anymore Yeah, that's it. The IBM Tempest PC. http://www.amazon.com/Tempest-NACSIM-5100A-Standard-Computer/dp/B007RWH1YC The bank I worked at had ONE of those when they were rolling out one of the first ATM systems in the state. Even way back in the 70s, the technology the FBI had for tapping into the communications systems to see what was going on the wire was very impressive to a 20 year old tech newbie. Heck, punch cards, punch card readers and COBOL were impressive to me.
