| Test Zexall |
Zexall : The program tests instructions (or groups of similar instructions) by cycling through a sequence of machine states, executing the test instruction for each one and running a 32-bit crc over the resulting machine states. At the end of the sequence the crc is compared to an expected value that was found empirically on a real Z80.
