Update April 2021. Thanks to fellow collector Andy Collins I'm now home to a really quite rare Genie III. It doesn't have a screen but that's a minor setback. Thanks Andy!
Not much unearthed about EACA so far, other than they were a Hong Kong based company that produced TRS80 compatible machines until they came up with the EG2000 which wasn't so compatible and therefore didn't sell too well. There's also a Genie III but I've not seen one in the wild so far.
Genie I EG3003 with tapes and manuals, boxed. Donated by Victor Hadden. Color Genie EG2000, boxed but no manual. Nice machine - looks borrowed from the Vic-20 I suspect! Color Genie EG2000, boxed and again no manual, but different machine.....more checking needed! Genie III Almost like hens teeth because so few were sold. NEWDOS/80 and CP/M 2.2/3.0 machine. EG2013 joysticks that actually plug in via a ribbon cable. Not much info on the web about these...
