Mattel Aquarius II

The Mattel Aquarius II (code-named Chess) had similar characteristics as his little brother, the Aquarius (code-named Checkers). Equipped with the same 3,5 Mhz Z80 CPU and the same 256 characters. But there were some differences as well. The Aquarius II looks more professional with its full sized keyboard. It even has a genuine spacebar!

Microsoft Extended Basic, which was sold separately for the standard Aquarius, is already built in to the ROM in the Mattel Aquarius II. The additional commands added some more graphical options, like drawing a line and a circle. The Mattel Aquarius I own has serial number 84.
