RE: HP-41C Extended Functions - 4K module?
To my knowledge ...
The Extended Functions/Memory module contains a 4KW (10 bits word) ROM and 127 extended RAM registers (889 bytes). Unlike the 41CX (page 3), the module uses one of the lower port address (page 8, 10, 12 or 14) for it's ROM part. There is no code for page switching in it. |
