Logic was DTL (diode/transistor) implemented with a single ceramic r/c network package, discrete transistors, and diodes. All PC boards were single sided.

pick-pg2.jpg 2005-01-12 184K Page 2 of the 1967 Picker brochure. This and page 3 are the only meat. Picker reworked the sales brochure and generally dumbed it down. The general sales effort was effectively ended.
