That's the document I was talking about (though, as you presumably
know, it's a different scan of it).

> Storage Systems Diagnostics and Utility Protocol 	AA-L620A-TK 	April 1982

> Storage System Unibus Port Description 			AA-L621A-TK 	April 1982

That is very much of interest to me.

What motivated this is that my MicroVAX-II emulator is getting to the
point where I think it may complete a build of the NetBSD world running
diskless, and I'd like to give it local disk.

But that requires knowing enough MSCP to build an MSCP disk emulator.
AA-L619A-TK has almost enough; combined with the NetBSD driver code it
may be enough.  But AA-L620A-TK and AA-L621A-TK will definitely be good
to have.

I've snagged copies of all three.  Thank you very much.
