On the software side I also have something to report. I had posed about the 6702 on my livejournal, including the source code for the emulation and the C version of the dongle checker. A "mr_z" posted a reply that he had discovered that the multiplication done in the dongle checker doesn't really have a special relation with the hardware. It is used merely as a convenient pseudo-random number generator. And indeed, if you replace that bit in the C code with real random numbers (as long as they're odd), the check still passes. -Olaf. -- ___ Olaf 'Rhialto' Seibert -- The Doctor: No, 'eureka' is Greek for \X/ rhialto/at/xs4all.nl -- 'this bath is too hot.'
