- You can get documentation about Mbus & Sbus - Actually, as I understand it,

- Sun does not own SPARC. Hmm, now that I think about it I'd have to mention
- that Sun does encourage clone makers (at times - they flip flop on this

- that they are "open" - or that the info is easy to get at but it does seem
