**FE3600/A/B/C  16/20MHz AT Chip set                              c:88
***Notes:...
***Info:...
***Configurations:
FE3600 (later named FE3600A) 16MHz:

FE3001  AT CPU Control Logic
FE3010B AT Peripheral Control Logic
FE3021  AT Address Bus Buffer
FE3031  AT Data Bus Buffer

FE3001 + FE3010B + FE3021 + FE3031

FE3600B & FE3600C 20MHz  (circa <1990):

FE3001A   AT CPU Control Logic
FE3010B/C AT Peripheral Control Logic
FE3021A   AT Address Bus Buffer
FE3031    AT Data Bus Buffer

FE3001 + FE3010B/C + FE3021A + FE3031

The difference between the B and C variants is difficult to determine.
The manuals  give conflicting information.   It appears it  relates to
the FE3010 chip. As  there are 20MHz diagrams that say the  B or C can
be used.
