I just found a copy of the original distribution/installation disks for EZ-ROUTE, a PCB layout and routing program, for Windows, from year 2000. It was fairly primitive but it worked; I used it a lot. If you want it, it's here: https://www.inglevale.com/EZ-Route.zip Contents of two 3.5" flops in a ZIP file. EDIT: EZROUTE seems to still be around!
