HP9800 Emulator update release 0.30


Dear friends and collectors of old computers,
a new release of HP9800E is available from


This release 0.30 contains new major functions, a completely new user manual, and some minor bug fixes. Please read the changes_0.30.txt.

Have fun.


I spent some time with the 9830 emulation during the last days. It is the most interesting machine for me, because it's the first HP Basic implementation on a desktop calculator.

A lot of documentation for the 9830 and ROM is available on The Australian Site, but I didn't find anything on the Infotek Fast Basic. Do these ROMs speed-up the Basic language, as their names imply? Any information will be appreciated.

I really liked the documentation, and the possibility to configure the optional ROMs. Great work, Achim!


(Still hoping to see a 9825/9835/9845 version some day...)
