There have been a couple of changes to the HP-65 Emulator and one of these may cause some confusion. Continue reading HP-65 Emulator Ver 1.03

Updated HP-65 Emulator
I’ve recently updated the HP-65 emulator. The new version says "1.02" if you choose [Menu/Display] [About].
HP-65 – Testing Subroutines
An emulator is supposed to mimic the behaviour of the real thing. It should do the same things, in the same way and give the same outcomes. But sometimes they don’t quite match. Continue reading HP-65 – Testing Subroutines
A Better HP-65 Emulator
I was wrong. The HP-65 microcode available on the internet works fine. See HP-65 R/S. It’s the emulators that are broken (slightly). See HP-65 Delayed Select Group. Here’s how I fixed mine: Continue reading A Better HP-65 Emulator
HP-65 Delayed Select Group
The HP-65 “delayed select group” microinstruction doesn’t behave the way you’d expect. I don’t know whether its behaviour changed for the ’65 or if it was like this on the earlier calculators too. Here’s what it doesn’t and what it does … Continue reading HP-65 Delayed Select Group
HP65 Credits
This emulator is heavily based on earlier work by Francois Roulet (http://home.citycable.ch/pierrefleur/HP65/default.htm).
That work also derives from others as credited on his site.
Whilst the Gss-HP65 emulator is based on the work of others, it has been modified and earlier contributors neither endorse this version nor are responsible for any bugs in it.
License
Francois’ work is published as CC-SA-BY.
Much of the earlier work has been released under versions of the GNU General Public Licence. Both licences are stated to be compatible.

The HP65 M Register
The M register in the HP-65 is used for a lot of very interesting things. Maybe not quite “give me the contents of the M register and I’ll show you the world”; but it is very close to that. Continue reading The HP65 M Register
Saving Magnetic Cards
The HP-65 and HP-67 calculators have the ability to save information onto small magnetic cards. This allows you to save and reload programs so that you don’t need to key them in again each time. With the HP-67 you can also save and reload data that is in the calculator memories.
With the emulators however, Continue reading Saving Magnetic Cards
The HP65 Emulator Menu
The HP65 Emulator has a number of extra functions available. You can access these from the menu and you can get to the menu by tapping the display.
Click here on the emulator.
Then you’ll see the following:
