General Information
The ETI 660 was published in the Australian magazine ETI (Electronics Today International) as DIY kit. The design was very similar to the Cosmac VIP and Telmac 2000. Like the Telmac 2000 the ETO 660 also used the CDP 1864 for video but the supplied system rom was also able to handle the 64 x 48 resolution and included a chip-8 interpreter.
