1960? B.C. (before cassettes)...

[Externet]

Hi.
Saw yesterday on an old television program, a short-lived audio tape recorder format NOT open reel-to-reel, NOT '8-track' type of recorder and tape cartridge, before the 'compact cassette' by Philips. Was not a wire reel either.
May have been a Hollywood trick of the era, but I do faintly remember seeing such before.

Does it have a name ? Was it just 'cassette' without the 'compact' ? Just curious.

Google lists Wikipedia and others with history of the compact tape cassette and the competitors Telefunken and Grundig. I think there was also a Japanese one or two. Philips won.
I worked in a Philips car radio factory when they developed their tape cassette player that replaced an 8-track tape player and their cassette soon became a hifi recorder/player. In the factory I also saw my first LED. The factory also made simple audio items and color TVs and I bought my first one that I souped up over many years.

Hello,

Waht to say about the early data cassette used in the EPSON HX20:

Not 1960 B.C. , but very old for computers (1982 - 1987).
I even had to work with this type of "computer".

The first computer I worked with used punched cards for the program and tiny ferrite cores on a matrix of wires for RAM.
Its logic ICs were RTL and DTL. I think it was in 1968.
