Mentor Graphics should give you a prize of " All Time PADS Lover.." :clap:
I have been in the Industry since 1977, I have never heard "PADS for DOS". So, man learns something everyday.. ;-)
I have been using it since the early 80s. The schematic program is Schema by Omation. Great programs. Pads integrated the
Schema net list so you can forward and back eco. I also use Wordstar on the DOS box.
As a one man consulting business, I couldn't afford to upgrade to the Windows versions. DOS code is compact and fast.
One other problem is that it can't export any file types except Gerber. It also is constrained to an Epson compatible Dot Matrix
printer for output. I have 2 Canon BJ200 ink jets. If I need to share schematics, assembly or other drawings, I have to print them and then
scan to PDFs. The schematic captures look great, and I can output BOMs.
The other problem is that I have hundreds of custom schematic elements and decals that I have designed and drawn over the
years, and at 73 years old, I am not up to starting over.
Anyway, I fixed the problem. Must have been a corrupted DOS system. Pads and other programs couldn't find files in other directories.
I am still working, but if my DOS box dies, I may have to retire (or shoot myself.)
