Just received a HP35s

[Thomas Radtke]

I know it was outsourced Derek, just like the 33s which has been debugged to some degree (even the LCD was changed). Actually the 33s still contained bugs that later appeared in the 35s also (lock up in loops with flag 10 under some condition), so we can safely assume they share the same codebase. Why the 33s could be modified and the 35s won't is beyond me.
