I really don't want to extract it, because I've found that MCA cards are a pain to get lined up, and mine has a RAM card bolted to it, so I have to line two MCA cards up AT THE SAME TIME.
Anyway, I can run VM, VSE, and various OSes in the MVS lineage. (I believe up to z/VM 3.x, quite a ways into the z/VSE family, and OS/390 V2R10.)
I plan on running VM/ESA 2.4.0, and maybe some MVS version, although I have to be careful, as MVS is very, very heavy for this system.
