4.3BSD Installation (probably off-topic)

I've been looking over the recent 4.3-ish BSD distributions now available from the PUPS archive. Thought I'd spin off a copy for booting on one of my spare uVax II's, but I'm stuck at (literally) before step one, and don't know where to go from here. If there's a more appropriate forum for these questions, I'd appreciate being redirected to them! OK, Before Step I, as doucmented in 4.3_on_uVax_instructions, is: YOU MUST ALREADY HAVE A WORKING VAX! These instructions are useless on a cold machine. You must have a 4.3 machine and a working uVax (probably Ultrix!) with a tk50 drive. Apparently, this is because the distributions don't boot on a Microvax, and the KA630 Microvax/MSCP/TMSCP patches must be installed and many things rebuilt on a 4.3 machine before a distribution tape can be built to put on a VAX. Is this an actual limitation on the 43reno.vax distribution currently in the archive, or not? If it is a real limitation, what non- microvax machines will the 43reno.vax distribution boot on? 11/750? 11/730? Tim.
