Hi Folks! Long time no activity so I thought I'd prime the pump. The Fluke 9010A is one of our most useful pieces of test equipment in our (and many other folk's) shop but I KNOW that it would be much more useful if the !@#$!% "Checksum Test" actually corresponded to the checksums that most of us are familiar with. We need some Z80 guru to dig into the code and rewrite that section and possible hardware mods might also be required. I really hate writing down every new checksum the stupid Fluke creates for future reference... Anyone game? John :-#)# --- Outgoing mail is certified Virus Free.
