Here's a Philips N1500. (this one isnt mine, but I have exactly the same model)

Dates from 1972. Has all the features that made up a domestic video recorder.
1 event 1 day (Cooker style) timer, cassette tape, built-in tuner.

130uM video-tracks, two head, guard-band colour (Chroma Under) recording, Eddy-current brakes used for both head and capstan servos. The tape speed was over 14 inches a second....
The cassette has one reel above the other co-axial style, the supply reel below the take-up, in a thick squarish boxy cassette, 1/2" tape was used.

Will record and play for 1 hour.

The later N1700 halved the tape speed and used slant-azimuth recording. Period modifications to the earlier N1500 included updating to the N1700 format by changing head disc and machining capstan pulley to halve the tape speed.
