Commodore CBM 3016 or PET 2001-16N

The first all-in-one home computer from Commodore was the PET. The first model was the PET 2001, including either 4 KB (the 2001-4) or 8 KB (2001-8) of 8-bit RAM. It was essentially a single-board computer with discrete logic driving a small built-in monochrome monitor with 40×25 character graphics. Designed on an appliance computer philosophy similar to the original Macintosh the machine also included a built-in Datassette for data storage located on the front of the case, which left little room for the keyboard. The data transfer rate to cassette was 1500 baud, duplicated for safety, giving an effective rate of 750 baud. The 2001 was announced at the '77 Winter CES in January 1977 and the first 100 units were shipped in mid October 1977. However they remained back-ordered for months, and to ease deliveries they eventually cancelled the 4 kB version early the next year.

Although the machine was fairly successful, there were frequent complaints about the tiny calculator-like keyboard, often referred to as a "chiclet keyboard" because the keys resembled the popular gum candy. This was addressed in upgraded "dash N" and "dash B" versions of the 2001, which put the cassette outside the case, and included a much larger keyboard with a full stroke motion. Internally a newer motherboard was used, along with an upgrade from static memory to dynamic memory and 8, 16, or 32 KB, known as the 2001-N-8, 2001-N-16 or 2001-N-32, respectively.

Sales of the newer machines were strong, and Commodore then introduced the models to Europe. However, there was already a machine called PET for sale in Europe from the huge Dutch Philips company, and the name had to be changed. The result was the CBM 3000 series ('CBM' standing for Commodore Business Machines), which included the 3008, 3016 and 3032 models. Like the 2001-N-8, the 3008 was quickly dropped.

Our model is the 2001-16N BS and was kindly donated by Andrew Borkett of the Faculty of Education in Cambridge University.
