It is interesting how DEC migrated from a "all known, all standard" system on UNIBUS and QBUS where any register address and bit was known to a wide varying family of machines where things are new all the time.
It was *never* the same. At the level of the kernel, VAX-11/780 UNIBUS is different from VAX-11/750 UNIBUS, which is different from VAX-11/730 UNIBUS. -- roger ivie rivie%ridgenet.net@localhost
