NOTE:

1. THE ADDRESSES DISPLAYED IN THIS MEMORY MAP ARE THE FULL 24-BIT IMB ADDRESSES. THE CPU16

ADDRESS BUS IS 20 BITS WIDE, AND CPU16 ADDRESS LINE 19 DRIVES IMB ADDRESS LINES [23:20]. THE

BLOCK OF ADDRESSES FROM $080000 TO $F7FFFF MARKED AS UNDEFINED WILL NEVER APPEAR ON THE

IMB. MEMORY BANKS 0 TO 15 APPEAR FULLY CONTIGUOUS IN THE CPU16’S FLAT 20-BIT ADDRESS SPACE.

THE CPU16 NEED ONLY GENERATE A 20-BIT EFFECTIVE ADDRESS TO ACCESS ANY LOCATION IN THIS RANGE.
