With regard to the "complicated calculation" the same could be said for the HP 67/97 diagnostic program, but in both the HP and TI calculators the test check a lot more than just the processor. Just loading the card tests the card reader and associated electronics, and the execution of the program would test some of the program memory, in the case of the 67/97 test all of it since the program just fits the available program memory, and ROMs since to carry out the functions called by the program would require accessing routines in ROM. It is even a basic display test since it ends displaying a bunch of 8s. Paul. |
