Here’s the very first model of the Sega Mega Drive.

That little ® next to ‘Sega’ at the bottom right means it is the first, Japan-only model.

The next batch of models, like this one, are missing the ®.

Sega loved covering the top of their consoles with semi-nonsensical text. For the Mega Drive it’s ‘AV Intelligent Terminal High Grade Multipurpose Use’.

Following the the tradition of the Mark III‘s amazing console top-promise (pic taken from my Mark III restoration article, hence no reset button and cassette slot flap)

And of course the inaccurate and needlessly complicated usage diagram on the top of the Master System.

Time for some launch games. The only true Alex Kidd sequel may be dated, but would have been pretty impressive in 1988. Especially because the early, made in Japan models have far better audio than later made in Taiwan models.
