Mainframe

The 7704A Mod 515C adds the ability to remotely operate the vertical, horizontal and triggering modes of the mainframe. Additional connectors on the rear are directly connected to the plugin-compartments to allow remote operations for the plugins.

P7001

The only modification to the P7001 was done on the z-axis/front panel pcb. A switch allowed to change to a longer timeout period for the external computer.

Further modifications by Honeywell

Honeywell replaced the feet of the unit shown on this page. They also added a cable tie holder and a tag to the back of the unit. The result got the Honeywell part-number 10066273-101 and the NSN number 6625-01-060-4390.
