Model 100 RST 7 ROM Hooks
Copyright 1986 by Bob Andersen, Micro Analog Associates. Monroe, CT. 06468
Routine RST 7 calls the nth 2-byte address specified in the HOOK table located in RAM, starting at 64218, where 2N is the value of the byte that follows the RST 7 instruction.
This study details the location and nature of all RST 7 instructions within a Model 100 ROM.
Default indicates the action installed by a cold start. Address 32755 is installed in the HOOK table for RET and 2267 is installed for FC ERROR.
