Hi all,

I have uploaded the new emulators to teenix.org

There are downloads available for the following calculator models.

HP35, 45, 55, 65, 67, 70, 80, 21, 22, 25, 27 and 29C.

The 67 is fully functional and can load and store cards to the PC hard disk controlled by its own microcode. It also has the option to "park" a card in the slot and wait for a [Pause] command before automatically loading it.

I created 24 program cards that cover all the examples in the 67 owners manual and are available with the 67 download.

The PC version emulates the 29C Continuous Memory and will "remember" where it was after turning off the power, changing calculator models or restarting the emulator. You can also "remove the battery" to force a reset.

The hardware emulator does all calculator models listed here, except the 29C does not have the continuous memory enabled as the PCB needs a modification which I will do soon. It will also emulate the 67 "park" function.

The older PCB designs will still run all calculator models.

The hardware memory cards can only store 51 programs per card now instead of 64, as the 67 uses more memory space per program. You can also mix and match 65 programs and 67 program/data on each card. To keep track of what's on them, a new [directory] function was added to the PC's programmer window.

I have also added a text based program card editor for the 65 and 67 with basic syntax checking and can accept listings like...

1. RCL 1
2. +
3. STO+2
4. CLx
etc

The text files can be saved as *.hpp files which are specially formatted to load directly into the emulator and for use in the hardware calculator. They include the headers, status info, data and checksums, plus they also have embedded program card image filenames.

There were too many changes to mention since the last update and I'm sure a bug or two will appear sooner or later, however I will fix them as soon as I am notified.

A big thanks to Bernhard for helping solve some sticky situations along the way.

cheers

Tony
