\"\"<\/a><\/p>\n

The HP-67 was a card programmable scientific calculator. For many years, it was the flagship.<\/p>\n

Features<\/h2>\n

– 224 program steps
– 26 data storage memories
– The ability to load and save programs and data
– Programmable keys (A-E)
– Subroutines
– lots more<\/p>\n

Advanced Features<\/h2>\n

– can be used without the advanced features
– microcode emulation
– microcode debugger
– you can display the contents of registers, data or program
– you can set registers or data
– you can trace microcode program flow
– supports breakpoints
– runs at the same speed as the real thing
– works the same way as the real thing
– supports non-normalized numbers<\/p>\n

“I like the Windows based emulators because they are faster internally than HTML5\/Javascript ones and this means I’m not having to trade-off the best implementation for what I can fit in a Javascript timeslice. I think I’ve done a pretty good job in both cases – but it was a lot easier to do with native code. The other good thing about Windows-based emulators is you have direct access to the file system. This makes it a lot easier to save and load files. For a HP-67 emulation, that means reading and writing magnetic cards as real files. You can copy the files, move them around, email them elsewhere; and so on. In the HTML5 emulators, I’ve done the best I can to make cards shareable. Again, I think I’ve done pretty well; but it still isn’t quite as easy as direct access to a real file. The downside of course is that Windows based emulators only run on Windows. I hope you like this emulator and the matching HP29w one”<\/em> – the developer.<\/p>\n

Downloading & Installing<\/h2>\n

You can download a copy by clicking the button below. It is a ZIP file so the process is:
– download it
– unZIP it anywhere you want
– double-click “run.bat”<\/p>\n

DOWNLOAD<\/span><\/a><\/p>\n

Buying a copy<\/h2>\n

If you buy a copy, there are a number of benefits for us all:
– you get to use the program forever
– you get all later versions for free
– I get some money to cover development costs for this and other software
– the creation of future software is funded<\/p>\n

If you don’t throw a few dollars into the pot, you’ll still get to use the program but it will stop working after 90 days. That is a lot longer than the usual 30 days because I do want you to try it, and I do think you’ll enjoy it. I also like to think that you’ll want to support it.<\/p>\n

If you’ve tried it and do want to keep it forever, you can get an activation key below. You can buy 2 copies if you want to contribute more. \ud83d\ude42<\/p>\n
