<>the latest. I know as the cover of my issue has the last of MITS number <>and a $1300 total and a mailing date in december 1974. <> < What do you mean "the last of MITS numbers and a $1300 total" ? No not quite, it was the first of the line if anything and early on to boot as I had it in my hands by January 15! Last was supposed to be list. < That's my point. The IBM was already being produced at that point and <being delivered shortly thereafter. Altair was still using the prototyp <machine and just starting to sell bags of parts as "kits". Keep in mind the cover of PE was composed and at the printer in in september-october 1974 time frame if not earlier to meet the publication schedule if it was to arrive in my home by mid December 1974!. I should point out that the 8080 by then had been in production about a year at that point. Allison
