167 EPROMS

[wbrown@csg.lbl.gov (Bill Brown)]

Perhaps this muddies the water a bit if, in fact, they do have them.  I seem to
recall something from Motorola a while back - AHA! - here it is:

The note mentions a 4Mb part which apparently may be used on newer mv167 boards,
but does not mention a part number.  I don't know if any (or all?) of our boards
are of the older or newer version.  It's quite likely that we have a mix, given
that some of our equipment had a "former life" in a different project.

I'm sending this to tech-talk as I'm sure other sites have the same questions.
