I agree, don't worry about the VCII+RS then. I already bought a battery for it, so I will probably try to temp power it / replace it first for practice. I'm in Electronics Engineering so I may find a use for it someday, or just as a museum to demonstrate VCII, NTSC sync suppression / Color burst shifting, or DES. Maybe hook it up to a logic analyzer and dick around with it (well kind of hard without a VCII stream), or use it as a doorstop.
As far as the time machine goes, I'm 32, if I could go back to the 90s for just 24 hours, boy that would be fun. The good old days.
