Huh, I'd missed that.  You're right, it was more like a stripped down 
PDP-10 than the Nova.  But it's definitely true that Ed DeCastro who 
designed the PDP-8 and I believe the PDP-X left to form Data General.

Now I'm thinking about the eventual fate of DEC and DG, both clobbered by 
PCs.  DEC came out with single chip package PDP-8 and J-11, and DG with 
single chip Micronova, but they were both too little too late.

I guess the PDP-11 was more influential, since the x86 series uses the 
11's (at the time) unsual little-endian byte addressing.
