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
> Collectively they make up the UDA50 Programmer's Documentation Kit
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

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