CADPAK (IBM only) CAT.# 157-D01-38

  CADPAK is a computer-aided drafting and design (CADD) program that is simple
  to operate and yet has the speed and power that professional engineers,
  architects and drafters require. Ideal for first-pass or conceptual design
  and drafting it creates 2-D drawings using the same features found in CAD
  systems costing thousands of dollars! CADPAK's easy to use drawing board,
  object-manipulation commands, area calculation and auto-dimensioning
  abilities, multiple levels and symbol libraries on-screen help, drag and
  rubber-banding of objects, and extremely affordable price make this a truly
  remarkable software value.

  CADPAK requires 256K of RAM. A color-graphics card or digitizer and a graphic
  printer or plotter are recommended. A 60-page manual is included.
