Looking for "Programming CalComp Electromechanical Plotters" book

CalComp published a book entitled, "Programming CalComp Electromechanical Plotters" in the 1970s era that contained documentation for software libraries for using the CalComp plotters. It's relatively obscure. The IBM 1620 Restoration Team at the Computer History Museum needs a copy for a project they are working on to interface a CalComp plotter to the 1620. If you've got a copy you can provide (all they need is a photocopy or scan) please contact Dave Babcock <dave at kaleidosoft.com>. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]
