No, it wasn't. It was a transparency that was used. It consisted of two transparencies sandwiched together, one for the monochrome part of TCF and one for the colour part. An electronic version was introduced in 1984.

The TCJ was a much later all-electronic version with a few differences - a slightly bigger circle, a slightly zoomed out picture of Carol and Bubbles and a few other bits and bobs.

The difference in the size of the circles is only about 2 pixels and wouldn't be noticeable except by direct comparison. TCJ was introduced in 1999.
