The 11/730 (and 11/725) CPU rivals the MicroVAX-I for
slowness (one is
30% as fast as a 780, one is 40% as fast), but is a solid machine. We
It has one other advantage for people like me. It's one of only 2 series
of VAXen (the other being the 11/780 + derivatives) that is built from
standard chips. The 11/730 is mostly non-protected PALs, AMD2901s, etc.
OK, there are _2_ custom chips, the ECC correcting logic IIRC, but most
of it is hackable.
If you don't have space for an 11/780, then the 11/730 (and its brother
the 11/725) is about the only choice for a hardware hacker.
