I'm afraid it doesn't work the other way!!  I have one of the dreaded STEs
with soldered SIPS rather than SIMMS and when I added memory I tried to
put 1Mb chips in the second bank with the 256K (soldered in) SIPS in the
first.  The machine only thought it had 1Mb!!  I had to unsolder the first
bank and put the 1Mb chips there (I added in-line sockets of course!).  My
system has 2.5Mb but TOS thinks it has 4Mb.  It seems to cause few problems
unless I try to use more than 2.5Mb!!  I havn't tried the famed SIMMFIX yet.
