Original HP 3000 brochure

[DougPeckover]

Hi everyone. I worked for HP in the early 70’s and am writing a book that contains information about the first release of the HP 3000. One of the brochures had three interlocking circles representing batch, online, and real-time instruments (this third was later dropped because it was one of the reasons why the initial performance was so bad). Does anyone have this brochure with the three circles? Thanks… Doug Peckover
