Credit where credit is due department:  the HCX-7 either is an OEM'ed CCI
Power 6/32, or is derived from it; the decoded instruction cache, etc. came
from the 6/32.  (The 6/32 instruction set is, indeed, similar to the VAXes,
although the addressing modes are different.  The 6/32 is big-endian (for
compatibility with CCI's smaller 68K-family machines); some 6/32 instructions
that are just like the VAX ones have the VAX instructions' opcodes, except
that the nibbles are swapped....)
