 * BUYING A CPU -- read next:

 * Design speed (to begin with) of the board is MC68030 at 16Mhz.  A 33Mhz CPU will not work.  Note that
   Motorola specifies maximum clock rate, and MINIMUM clock rate for 68030 CPUs.  The minimum is typically
   about 60% of the maximum, so a 33Mhz CPU may run as slow as 20Mhz. 

 * Memory is 16Mb 60ns 72pin FPM or EDO SIMM.  Micron spec used.  Samsung & TI specs look to be the same.
 * SIMM may be single-sided (16Mb) or double sided (32Mb).
 * One SIMM or two SIMMs may be used.  First goes in slot A.  
 * Larger goes in slot A, if of different sizes.  "DOUBLE" jumper 1-2 for automatic determination of size.

        Design is to Micron FPM or EDO spec.  4Mbx32 60ns, or 8Mbx32 60ns.  (16Mb up to 2x32Mb parts)
        Design may accomodate 64Mb and 128Mb parts also (up to 256Mb), but this has yet to be verified.   
| SIMM702    MT16D832  AMP/Tyco 582-2021-?  (Jameco 962074); many others will fit hole pattern.

| U801       MC68030RC   use -16 or -20 part, -33 part will not run at 16mhz; + 124/128 PGA socket
