>>> Was your purchasing decision ever affected by the availability of >>> schematics? Part of the awesome aura of the long ago & then great Hewlett Packard was that their manuals included highly detailed circuit diagrams of their equipment complete with detailed BOMs. Memory even suggests they may have had a circuit operation description. And for arcane magic the HP hournal described in great detail what they did and why and how. "Copy us if you can" seemed to be the challenge. Alas, those days are gone and HP are just another bunch of consumer exploiters. Not terrible products, usually, but the glory days have gone.
