I found an item based on a Commodore press release in Byte Magazine, February 1978, Page 190. This establishes the first shipment as mid October 1977. Commodore Ships First PET Computers (Photo of Chuck Peddle) The PET computer made its debut recently as the first 100 units were shipped to waiting customers in mid October 1977. Here Commodore Systems Division Director Chuck Peddle is pictured with the PETs undergoing final checkout. Shipments were made about six weeks later than expected, according to Peddle. The delay was due in part to time consuming quality control measures and the material flow problem in starting up the production lines. "In this business," Peddle argued, "six weeks is actually pretty good." Many of the first units were delivered to customers who intend to develop software for the PET. Commodore plans to create a publishing house for programs developed by users as well as employees. The company plans to increase production of the PET computers to several thousand per month by early 1978. The basic PET with 4 K memory is priced at $595, while the 8 K memory version is $795, (415) 326-4000.
