What the icons meant?
This computer was launched to sustitute the C=64, but even with a best (7501) and double velocity CPU, four applications programs in ROM (spreadsheet, word processing, database and graphics), graphics with more colours at the same time in screen (128 simultaneous colours), it was several disvantages, it hasn´t sprites, it was a worst audio capabilities than the C=64 was (it was only two voices or one voice and one noise and the C=64 was three voices plus one noise), you can´t use the joysticks or casette for the C=64 with the plus/4, but you can use the C=64 disks drives, and the most important thing, it was incompatible with the C=64 software. All of this become in a poor sales and Commodore stop the production of the computer and make a C=64 compatible one, the C=64c.
