In the CSRG DVD set there is some cci ports of 4.2BSD… stuff is #ifdef’d Tahoe in there so it’s not hard to pick out but it doesn’t seem to have anything really documents looking.
I could be 100% wrong though, but they just look like ‘clean’ source trees. Not sure if sanitized though.
The assembler shows 182 opcodes …
/*
* Boot program... arguments passed in r10 and r11 determine
* whether boot stops to ask for system name and which device
* boot comes from.
*/
/* r11 = 0 -> automatic boot, load file '/vmunix' */
/* r11 = 1 -> ask user for file to load */
The stand/boot sounds awefully vax like with r10/r11…

Really good point -- I saw some years ago, but never owned a copy.

Is there even a single shread of documentation though? It's a daunting
task trying to write an emulator based only on inferring the internal
workings of the machine from 4.3BSD source code. Mind, the end result
wouldn't be too interesting; hey it works... just like a VAX.
