Commodore PET
 

These computers are new versions of the PET series. The main improvement was the new ROM version (v4.0) which offers new possibilities such as direct disk operation commands (DLOAD, DSAVE, COPY, HEADER, etc.) or the ability to repeat cursor control characters by holding down keys. Late models also had a larger screen (12'') than the 2001 computers.
The disk drives are "Intelligent", which means that they are CPU driven (MOS 6502) and have internal RAM (4 KB) & ROM (16KB, which contains the DOS).
The 4032 and the 4016 were sold with an 80-column dot matrix printer (5x8 character matrix). This printer (4022) was an Epson printer with a Commodore name on it.

Emulator
VICE is a program that runs on a Unix, MS-DOS, Win32, OS/2, Acorn RISC OS or BeOS machine and executes programs intended for the old 8-bit computers. The current version emulates the C64, the C128, the VIC20, all the PET models (except the SuperPET 9000, which is out of line anyway), the PLUS4 and the CBM-II (aka C610).
