Oops, you're right.  My own web page has the correct info, but my
memory is terrible.

Now that I think about it more, I'm fairly certain that it won't,
because 2000E (and 2000F and 2000/Access) require the floating point
microcode that is not available for the 2114/2115/2116.

How much memory can a 2114 be equipped with?  That's another potential
problem with trying to use a 2114 for either 2000A or 2000E, or as a
system processor for the dual-processor versions.  The 2114 might also
be short on I/O slots, though it has enough to be an I/O processor
for 2000B and 2000C.
