RAM Datassette
The PET shipped in two models; the 2001–4 with 4 KB of RAM, and the 2001–8 with 8 KB. 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 2001 was announced in June 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 canceled the 4 KB version early the next year.
