Does anyone have the DIP switch settings for these Evergreen 486 SuperChips? They allow you to use a Cyrix 486SLC on a 286. Thanks.
EDIT: Found them. Attached in pdf here:
EDIT2: in text as well
SW1
ON = Double CPU speed using a 2x multiplier on the Evergreen interposer (not on the CPU)
OFF = Do not use Evergreen's 2x multiplier, meaning that it uses 1x
SW2
ON = Set for AST, Sperry, Unisys, etc. Used to obtain compatibility in systems having a slightly proprietary architecture
OFF = Set for IBM, Compaq, etc.
SW3
ON = Set SuperChip to match a system with a 16 MHz system clock
OFF = Not 16 MHz system
SW4
ON = Set SuperChip to match a system with a 12 MHz system clock
OFF = Not 12 MHz system
SW5
ON = Set SuperChip to match a system with a 10 MHz system clock
Off = Not 10 MHz system
SW6
ON = Set SuperChip to match a system with a 8 MHz system clock
OFF = Not 8 MHz system
SW7
ON = Set SuperChip to match a system with a 6 MHz system clock
OFF = Not a 6 MHz system
SW8
Always ON factory setting.
