            CPU     Slots  Max memory   Comments
Mac LC     68020    1(020)   10 Mb?     No Apple FPU available (3rd party)
Mac II     68020    6(Nubus) 14 Mb*     Upgrade to Mac IIx or Mac IIfx avail.
Mac IIx    68030    6(Nubus) 14 Mb*     Mac II & IIx both 16Mhz
Mac IIfx   68030    6(Nubus) 128Mb(7)   40 Mhz; 32-bit clean ROM
Mac IIcx   68030    3(Nubus) 14 Mb*     Basically a IIx with 3 slots
Mac IIci   68030    3(Nubus) 128Mb(7)   25Mhz; 32-bit clean ROM
Mac IIsi   68030    1(below) 17 Mb(7)   20 Mhz; 32-bit clean ROM

*Maximum amount of memory addressable under System 6, using every trick
known to the Dogcow.  IIcx has ROM SIMM slot, may receive upgraded ROM;
if so, goes to 128Mb max.

(7) Addressable under System 7, outrageous numbers due to 16Mb SIMMS;
but it's possible.  Unknown if IIsi supports 16Mb SIMMS; if it does,
max memory on IIsi is 65Mb.

(020) Mac LC has '020 Direct slot, unique to LC.  Many 3rd party mfg's
are making cards; so is Apple.

Mac IIsi slot can be set up with adapter for either Nubus or '030 Direct
(like SE/30, but cards that cheat on the SE/30 may not work).  There are
also many cards that connect directly to slot.  FPU must be installed via
slot card; no socket on board. 

Hope it helps.
