Emu28

Emu28 is a lightweight software utility developed to work as an emulator for HP18C and HP28C, a series of Clamshell calculators, enabling you to work in a legacy environment, but on your own computer.

Subsequent to the installation process, you need to copy your ROM images into the same folder, making sure its name coincides with that of the KML script.

The scripts are meant to indicate the visual appearance of Emu28, and by customizing them you can also customize the interface of the emulator. Bear in mind that for the program to function properly, you need one or more ROM images.

ROM images are computer files that store information from a read-only memory chips, generally associated with old games or firmware, by means of which these can be run on a modern computer, through an emulator, such as Emu28.

The virtual keyboard displayed by Emu28 can be used either with the actual PC keyboard or with the computer mouse. From the File menu of the utility, you can start a new emulation session, once again being asked for the KML script that you wish to use.

In terms of configuration options, the application allows you to change its ‘Settings’ sections: ‘General’, ‘Disassembler’ or ‘Sound’. The first lets you modify the authentic calculator speed, the title, menu, and other preferences, such as keeping Emu28 always on top, running in single instances or automatically saving files.

The ‘Dissasembler’ area lets you opt for an assembler syntax: ‘HP Mnemonics’ or ‘Class Menmonics’. The ‘Sound’ section enables you to adjust the volume and default sound device.
