Good points |

Bad points |
Memory size was way too small. To increase it meant buying an expansion box plus the memory card. This increased the price to £200 for an 18 KB machine. |
How successful? |
One of the least successful of all home computers; only around 10,000 were sold. |
Comments |
The Mattel Aquarius was disastrously underpowered by the standards of mid 1983, compared to the likes of the Sinclair Spectrum and Commodore 64. Expanding it to a reasonable amount of memory made it more expensive than its rivals. (At this time the 48 KB Spectrum cost £130.) |
