This implies that the order would have been placed with HP earlier than 1982. In PPC Journal V8N1 (Jan/Feb 1981) on page 5 is the monthly "ROM Progress" column where it was announced that the completion of the initial testing of the ROM image in the HP software development system was Feb 17, 1981. In the accompanying member letter with PPC Journal V7N8 (Oct 1980), Richard Nelson wrote: "..I have officially placed the order with HP and gave them the check for the tooling..." So 1980 it is. Thanks, Jake |
