When I upgraded my DS700 I talked to a RAM supplier and read out the
Samsung numbers from some DEC parts I had available, and they identified
them as a standard 72-pin PC SIMM.  However, now I can't recall _which_
standard...  Sorry.

The tricky thing with the 90TL is the problem of physical space.  The
SIMMs from the 700 won't fit in, but only due to the location of the
socket, the surrounding chips, and the proximity of the case.  I think
the DS90 SIMMs only have chips on one side, for a start.

If you can get someone to open up a 90M and identify its SIMM (I think
they use the same type) you might be onto a winner.
