AFAIK the first generation of rocket controll computers
(thrust, angle, etc.) had HDC-601 processors (with plate
wire core mem), And if I'm not completly wrong, the HDC-601
is a DDP-516 compatible system. I don't know if the shuttle
engines have been equipped with them, since the actual
controlers are (since the mid 80s) are based on 68.000
processors.

And for the AF-101, I always belived the last core mem unit
was named AF-101F not B, as mentioned in another message. In
fact, I love the idea of using a /370s design CPU - It's just
the best OPcode design ever :)

BTW, does anybody know if a new design is planed ?
