Release Notes:

Thank you to the user who reported the problems.

Happy Again - The first programmable calculator I ever purchased was an HP-67 when they first came out. I could do pretty much everything I ever needed to do on it. Unfortunately, first the card reader quit working then the calculator quit working. This application, however, seems to work just like that old calculator. Now I wish I hadn’t thrown away the handwritten copies of all the programs that I wrote for it and the programming packs I obtained from HP and others. The big advantages to this are that I can see the program and don’t have to step through it one step at a time. I can test the programs and see what is happening in all the registers. This is just plain awesome.

No documentation - Unless you’re familiar with the HP-67 - or have its manual - this calculator is not very useful to you unless you are willing to invest the time mastering it blindly. Certainly a person schooled in the sciences can figure it out - all the functions are there - but why should one have to do this? And I would bet the manual for the HP-67 exists somewhere on the internet. But complexed tools, such as this, usually come with documentation. No documentation here. None. Personally, I consider my time too valuable to spend an inordinate amount of it learning to use what is a basic but complicated tool when alternatives abound. Alternatives with appropriate documentation.

Just OK - Copy/paste is not friendly. Can’t paste numbers with comma and/or space for example 1, 2345.50. Does not provide mouse button (right click) menu.
