Shore - 06-21-2020 01:47 PM The document covers the following operations: NOT: for integers AND: for positive integers OR: for positive integers XOR: for positive integers Simple conversions between Binary and Decimal bases (integers up to 1023) No extra or additional modules required. Should work for the Swiss Micros DM41 and any emulators.
