I have Generic CADD level 3 sitting here - I bought it new and used it for quite a while until Autodesk bought the product and ruined it - it is a great 2D drafting program that will run well on a 386 or 486 computer with a mono-graphics display (or of course a better display) - I mostly used it for drawing block diagrams, but I also used it for laying out cuts for sheets of wood for various projects. it works with a mouse or with keyboard shortcuts that I still remember (control R for rectangle, for example) (sad, isn't it) - I don't need this any more - find my email off my web site (wbnoble.com) and drop me a note if you are interested - I figure $20 delivered in the USA is about right - it has several of the add on programs included, all the disks, etc.
