System 1M Manual

[artao]

I just purchased a used System 1M with the ProMars plugout.
I found this single page "manual" thing, but it hardly goes into any sort of depth on the unit. Is that seriously the only manual?
I also found the ProMars manual, and that's arguably a better manual than this single-sheet System 1M manual I found.
Also, where and how do I get the VST versions of the System 1M and ProMars? I figured I just had to make a free Roland Cloud acct and they'd be available. But they're not. I don't even see the ProMars listed ANYWHERE in there, nor really anything regarding Sys 1/1M/8 plugouts in general.
