Good point ! Although you can share the config disk I think (Maint CFx
disks).. IIRC, SYSTEM CONFIG has provision for being used by multiple
systems.. But yes, I misconstrued your statement.

AFAIK, MIF/EMIF came pretty early with LPAR. I think even the 3090 S or
J models had MIF/EMIF.
Err.. Even with a small CP nucleus.. I don't think you could ever run
VM/370 R6 with less than 512K

I think the smallest S/370 you could run VM/370 R6 was the 370/138 Model
1 (with 512K) - and that was pretty much borderline.. You probably
weren't left with much more than 30 or 40 pages for virtual machines at
that point.. The 370/138 Mod II already had 1MB.. Not sure about the
158, but it must've had at least 1MB.
