Let's see if I can kill all these birds with one post.

IBM 486SLC: used in the TP500, 700, and 720.  Comes in "normal" and
clock-doubled versions.  The 500 and 720 use the clock doubled versions.
24-bit memory bus (16MB max), 16-bit data bus, 32-bit internal, no FPU,
16k cache.

IBM 486BL: aka "Blue Lightning."  Used in the TP510 and maybe the TP425.
Comes in "normal" and clock-doubled/tripled versions.  32-bit memory bus
(4GB max), 32-bit data bus, 32-bit internal, no FPU, 16k cache.  Before you
ask, the TP425 is like a TP350, only it's sold at schools.

Intel 486SL:  discontinued, used in the TP750, only came in 25MHz and 33MHz
flavors.  32-bit memory bus, 32-bit data bus, 32-bit internal, with FPU
(except a version used in the TP350), 8k cache, on-board power management
and motherboard features.

Intel 486DX, DX2:  The standard, used in TP755 and TP360 (? SX version).
32-bit memory bus, 32-bit data bus, 32-bit internal, with FPU, 8k cache.

Intel 486DX4:  Clock tripled, 32-bit memory bus, 32-bit data bus, 32-bit
internal, with FPU, _16k_ cache.  Costs more than a TP500. :-)  TP755 only.

You should try Dolphin sometime.  Real good tasting.  (The fish of course,
Mahi Mahi :-)
