For discussion of Sun, ORACLE, and Fujitsu's SPARC64X computers, software etc.
Looks like uunix was on a 3.x firmware but I'll have to dig through my notes because I did figure out a workable way to reprogram the NVRAM with OBP 4.x without mkp/mkpl. It involved finding the base address of the NVRAM and writing bytes directly using different Forth commands. This was on my Sun Blade 100 which I installed a new ST chip into.
