Hi all. I'm going to show my age here - I'm trying to update an old CAD drawing and am missing some hardware physical dimensions. Would anyone have, know where I can find physical planning templates of some old IBM hardware - specifically the IBM 3800 printer, 3480 tape drive, Series 1 (4954/4956), 3081 and 4381 processors? If not the templates themselves, the publication number(s)? IBM used to publish all hardware planning information - in their hardware bible and as what we used to call "flimsies" - the clear plastic 8.5 x 11 sheets one could use on a floor plan, graph paper or on an overhead projector.
