Hello, I recently got a second model 33. It had a modem, but it has been removed. The system also had its on/off/local switch removed.

Is this a UCC-6 call unit based on the attached picture? Am I best off wiring in a new switch?

The new board you can see is my RS232 adapter. The system seems to move well, belts are good, hand rotating the shaft everything looks great, keying looks like the keyboard is working fine, so pretty excited.

Thank you,

-Eric
