1984.

Commodore Plus/4 was somewhat "heavier" than the light-version Commodore 16. Both were built around the same processor and non were little or nothing compatible with its predecessors VIC 20 and Commodore 64. Both were also "flop-mates".

Commodore Plus/4 did flop even though the processor was the most recent and the language was stronger than ever before. And that it also had built-in programs such as word processing, database, spreadsheet and a program for graphic display of calculations. Via the serial port you could connect the existing equipment such as printers and disk drive. But there it ends.

No other peripheral devices or software than those included, were compatible, because of the newer BASIC language. How about the built-in programes then. Well, they were quite lean. Word processing - just over 7600 characters, spreadsheet - 17 columns and 50 lines, database - 999 archives with 17 fields and 38 characters per field and finally, the graphical program that only could show grafic bars in text mode. In order to have these facilities and the newer language, Commodore Plus/4 had to sacrifice something. It had to be something that Commodore 64 had - one of the three channels and, not the least, the sprite generator. Sprite is the one who fixes animated games. It goes without saying, that if you can not play games, peripherals must be purchased new and if the firmware is too weak, no one will buy. It became a flop and curtain down.
