Commodore Professional 2001 (PET)

UvA Computer Museum catalogue nr 00.15

The CBM (Commodore Business Machines Inc.) 2001, also known as PET (Personal Electronic Transactor) was introduced in 1977. Some of its characteristics are:

9" CRT, 25 lines of 40 characters
MOS Technology 6502 processor, clock 1 MHz, 8 kB RAM, 14 kB ROM (for operating system and BASIC interpreter)
(audio)cassette drive for data storage, effective transfer data rate 600 bits/sec, using Commodore's proprietary data format. Hence on a 30-minutes audio cassette there was room for about 120 kbytes.
IEEE 488 General Purpose Interface Bus connector

The CBM 2001 has a peculiar keyboard. From the simple graphic patterns corresponding with the various keys, primitive pictures could be assembled.
The machine has been very successful among computer hobbyists though it was designed for the professional market in the first place. It was sold for US$ 1600.

This machine was donated by Mr. J. Franssen.
