Unisonic 21 Jimmy the Greek (1977, VFD, Model# D-2)
These are Blackjack computers with built in calculators. I believe they are all pretty much identical in functionality, just different sizes/body styles. They are all called 'Unisonic 21' and are endorsed by Jimmy the Greek. The larger models come with a vinyl cover, and the calculator sized ones have a normal slip-case common with calculators. So far I've found two different versions of the tabletop and two versions of the handheld sized one. D-2 is the model # of my tabletop in the blue box.
Calculator sized versions (Uses 3 AAA Batteries, 1st ver Model# 21-PI):
Do I have this? Yes, top version boxed, 1st version of calculator
