This Australian computer was in fact built and conceived in Hong Kong by Soundic Electronics, which produced a lot of low-end products at that time.
The high-resolution (256 x 192) can only be accessed with at least a 16k RAM extension.
The Basic (SD-Basic 2.0) is supplied on a ROM cartridge, it allowed to display up to 32 sprites.
The Pencil II also came with an interesting expansion cartridge. The regular cartridge port was the exact same size as a Colecovision cartridge, and when you plugged the "Colecvision Support" cartridge into the side of the unit, it played regular Colecvision games.
Unfortunately, very few games and applications were developped and the Pencil II quickly fell into oblivion...
