Holy Moly I can't believe I found this Mattel Aquarius in Vintage Gamer in Halesowen near Birmingham, it's quite a rare machine as it was only on sale for a few months in 1983, this one is boxed (but with no polys) and is in immaculate condition apart from the model label which is starting to peel off now The Aquarius was made by Radofin which made the previous Intellivision console, it has a Z80 as the processor, 4K of RAM (expandable), 8K ROM with Microsoft BASIC, monophonic sound (expandable with the expansion block), a horrible rubber chiclet keyboard, and character based graphics, similar to PETSCII. There was an Aquarius 2 but it was not released in any great numbers Top and bottom of the box The two sides, the opposite sides are identical A free RF lead, it isn't the original one The top and bottom, the machine itself feels really well built and sturdy, it is about the size of an Acorn Electron, or a Spectrum 128 (Toastrack), with a fair weight to it, it feels good. There is a green LED to the right of the Aquarius legend There's a main switch on the side On the rear, ignoring the cartridge slot, is the printer port, cassette port, the H-L switch which isn't populated in Europe, RF out and the permently attached cable to the PSU Here is a close-up of the rubber chiclet keyboard, this somehow manages to be worse than the original Spectrum, and the RST key wipes any programme in memory, it does have a collar around it, but it's still far too easy to press. Also, there's no delete key!But it's still not the worst keyboard, that honour goes to the Oric 1 This is the cartridge slot, the on board RAM is only 4K, this cartridge adds 16K for a total of 20K. There would have been a plastic cover over this for when no cartridge is installed, but I didn't get it The cartridge itself A program catalog is all the documentation I got with the machine The hard wired PSU This machine is fully working, the boot screen cycles through Blue, Green, and yellow colours Pressing Return takes you straight to BASIC, and my usual programme works just fine here Here's a video of the boot screen, I like it a lot, however the BASIC screen is just blue, I can't imagine how annoying it would be typing in a programme with the background colours cycling away R - Tape loading error, 0:1
