<I can't get to the bubble memory chip because it has a metal shield
<spot-welded around it. Wrapped around 4 of the 6 sides, so to speak. I'=
<ve tried removing this sort of thing before - nigh impossible without a
<chisel, and I'm not about to do that.
<Chip has 12 pins/side, for a total of 24, if that helps.
Peeling the shield would destroy the part. It holds in place the magnets
used for fixed bias to maintaining the bubbles during power off. There
is nothing much to see under it.
