Montedel C2-670 Remote Control Unit

This is a Montedel C2-670 Remote Control Unit, serial number 0078.

Montedel is (or was?) a member of Gruppo Montedison.

Modes (of the unit being controlled, of course) are AM and MCW, and the range seems to be 200 to 399.975 MHz in 25 kHz steps. Although that decimal point is misleading.

It's all TTL, 54xx Military temperature range. I'd say it's probably just a long shift register that shifts the switch settings out and the lamp setting in in some way.

I suspect the "69" is the date of manufacture.
