Now wait a second.  The TP750, 750CS and 750C all use the Intel 486SL/33
CPU which has been discontinued.  Even if it were socketed, I doubt a 486DX
would fit in its place - the SL has some functions built into it that are
missing on the DX/SX.

The 750CE uses a 486DX2.  As does the 755 series.  But the 750CE is an
earlier incarnation of the 755 (and predates the DX4), so I'm not sure the
CPU is socketed.  The 755 series *is* socketed.  At least that's what I was
told when I asked IBM soon after it was introduced.
