Similarity to the Tron score

This used to be one of the staple sci-fi films I watched as a child in the early 80s.

Watching it now I can hear such a strong similarity to the more twinkly parts of the score here and the score in Tron.

Obviously this was made fist and may have been an influence on Wendy Carlos but even still it's striking.

It's not a complaint though. Every composer gets influence from somewhere but I thought it was worth mentioning.
