Now, they are specifying .010” .. I’ve no idea what thickness the original TVT boards were, but I’m guessing they were probably thicker (.06ish?).  Thoughts?

 

Way back then (60's-70's), the very thin boards were used for commercial production.  Hobby boards were thicker - 0.062"  probably most common.  I recall using 0.12" boards for things (like keyboard substrates) that required mechanical strength.
