Ahh... slight syntax incantation diff.

I was routinely doing the init/unjam thing, so that much was good.

OK, if that were the case then flipping the switch might have helped.
Alas, the boards are outgoing, so I will file this tidbit for the occasion
that I run across another such MVII, in the surplus pit, here at MOO U.

When Mr. Stiebler gets the board, maybe he can check what the switch setting
is, so we can know for sure.  My curiosity is getting to me, now.

IFF that is all it was, then the gentleman that got the dual ram boards
has two good boards instead of one good and one fer parts......(:+}}...
That should make him happy.
