The parametron computers were late 50's/early 60's, not 70's.

CHM has a brochure on the NEC box:

Herb Grosch mentions meeting Eiichi Goto in his "Bit Slices" autobio:

If you search on the Kana string for "Parametron", you'll find lots 
more:

Here's a page full of links to various PC-1 resources (many in 
English):

...and there's Eiichi Goto's parameteron patents in the uspto.gov 
database (I'll leave the search to you; it's pretty easy).
