(Thematic - Business) Portland Area High Technology Evolution, Cacy & Linch, 1984 The trajectory is familiar to post WW-II tech regions where small businesses started in basements by electronics hobbyists and amateurs, and turns into brick and mortar stores. Companies like Hawthorne Electronics, one of the earliest companies shown would become a general electronics shop that built oscillascopes in back, with a store in front. Tracing the roots and evolution of numerous companies a few notables pop up like "Frye Electronics" that began in 1973 and continues today. Interestingly while there are numerous software companies later on the chart, there are still a number of hardware based companies dealing in telecom, semiconductors and more. Uncommon. Condition is good with some scuffing and loss to the back of the sheet, mild dampstaining, but amazingly not affecting the front. Overall size is approximately 23 x 35 (inches) $185.00
