I've wanted a Commodore Plus/4 for a long time. I really like its design. In addition, it comes with Basic V3.5, with many more controls than the Commodore 64.
Purtroppo mi è arrivato... non funzionante. Sul blog trovate i video relativi all'unboxing, test and repair.
E' un computer piuttosto interessante, anche perché la Commodore ambiva a raggiungere gli utenti professionali in ufficio, con la suite di software già inclusi nella ROM del computer: un elaboratore di testi, un foglio di calcolo e un database).
The boot screen of the Commodore Plus4 (also called Commodore 3+1) is very similar to that of the Commodore 16.
The Commodore Plus/4 is a home computer from CBM (Commodore Business Machines), released from 1984 to 1986. It belongs to the Commodore 264 series: a family of home computers that also includes the Commodore 16 and the Commodore 116.
