HP95-C Simulator

[teenix]

Hi all,

I have posted a simulator for the HP-95C at http://www.teenix.org

This printing scientific calculator was never released by HP so it might be a bit of a novelty to try out.

The main features are the continuous memory and the ability to partition programs allowing up to 4 separate programs to be stored at once.

The simulator uses the HP97 microcode as its backbone so all calculations should work as expecting from this series.

The programming side (entering and running code) is all handled by the Windows program which hooks into the 97 microcode code when required. This proved to be quite difficult so there will probably be a bug or two that I missed.

The printer output has many differences to the 97 as well so a lot of this code is intercepted by the main program before the 97 gets to do any printing.

cheers

Thanks ! Evidently the HP-95C was the only one of that series to have continuous memory, right?

As far as I know.

I think the closest printing scientific model of that era would be the smaller HP-19C.

Thank you! Thank you! Thank you!

It is so wonderful to get one's hands on an HP-95C emulator!!!

Awesome! Thanks, Tony!

Possible bug: [g][R↑] is supposed to clear the Sigma registers, but instead it seems to perform a [R↓].

Thanks for the feedback - definite bug :-)

I had a typo in the HP97's intercept code for that function, seem ok now.

New download available

Hi all,

I just realised that the Sigma memory was overlapped with storage registers R.0 to R.5

I have repaired this fault and a new download is available.

cheers
