- ULTRIX V4.2A is for RISC systems only. You can run V4.2 or V4.3 on a
- VAX system, but not V4.2A because there IS NOT a V4.2A for VAX system.

- By poking the right registers you could probably arrange to boot off
- a MASSBUS tape drive, if you can find a bootable 9 track tape. You
- might even be able to find in some very old documentation a machine
- code program for booting off a UNIBUS tape drive (TU80 or TS11). The
- V4.2 or V4.3 distribution for the 11/780 should come with appropriate
- standalone RX02s, so I doubt you'd need to boot off something else.
