Extra bonus if you can implement a full vector per register ala the 48 series. It's much easier to keep track of than spreading each vector across 2 registers. Of course polar and rectangular settings would apply. If nothing else, these are interesting problems to solve while you're stranded. Hope you get home soon. Brad

Full up With plenty of memory and program space, I'm sure programs could be sorted out. As an aside, I've found a single chip solution to implementing the CX on a 67 replacement CPU board. As well as the replacement 67 software, I've implemented all the HP calculator cores that are required to run the CX. A mind boggling amount to go though, if time permits. cheers Tony

RE: HP97 The journey begins
The market price of a HP67 will rise to immeasurable heights. Especially with the defective models :
Tony, please wait until we all have a second for the upgrade ;)

I've been keeping an eye out for a nonfunctional 67, they seem to be pretty rare.
