Re: HP-80 Teardown with pictures Message #8 Posted by BShoring on 24 Oct 2013, 5:26 p.m., in response to message #1 by Max Stone
Thank you very much! This is very interesting. There is lots of info on the HP-35 but really little on the HP-80. It is really impressive just how much functionality they packed into the HP-80 considering the limited memory at the time. Unlike all the later financials, the HP-80 had to perform all the financial functions on the stack as there were no dedicated financial registers. Somehow it managed to keep track of what values were where and it performed the calculations correctly.
I did find the same dusplay bug you mentioned on the HP-80 iOS emulator I have (from Maciej Bartosiak).
Thanks for a great job!
Bob
