Stephanie, I think Sandy hit it on the head. The FCC wanted to know where these units would be in the early days. A microwave oven does radiate RF energy which could cause interference to other services. Try locating a WiFi router on channel 6 next to a microwave! It is a bit odd though since the frequency used by microwave ovens falls into the ISM band which were established in 1947 so there wasn't much that RF heating devices could interfere with.

Cory, any idea of the vintage of those cards? Late 70's??
 
Yep, essentially these are self-contained radio transmitters and I assume the FCC wanted to know about sales/location. Also note the question about whether the Distributor will be servicing the unit.

Based on the model number on the top of the card (RR-9) I'd peg these as 1976/77.
 
I always thought those registration cards were used to send you junk mail advertising for the company. On one of them I intentionally misspelled my name in within 30 days I was getting tons of it in the mail with the misspelled name! So we never send them in.
 
cool reg cards!

however you might not be so enamored of 80 column punch cards if you'd been a programmer back in the '70s punching out 3" thick card decks for submission to the main-frame operators...no such thing as WiteOut for a miss-punched hole!
 
Roger:

I remember those days well - my first experience with computer anything was IBM mainframe using Hollerith (keypunch) cards.

The greatest advance in computing was not Eniac. It was not random-access memory. It was not even the first Pentium chip.

IT WAS THE DAMN BACKSPACE KEY! :)
