Looking for old DOS software

[Raymond Kaiser]

Does any one know where you can go to find any used version of PSpice and
PADS DOS software, full version. I presently have the evaluation versions
but they are limited. Do companies recycle this old software when they
upgrade?

why such junk is necessary, i can imagine any DOS-based PSpice will also
suffer from extremely obsolete models and simulation is totally worthless,
same with PADS- how would you get satoisfactory graphics in DOS??

Easily. DOS-based schematic capture did not have the "advantage" of
relying on the OS to provide graphics services, so much of the
development effort would go to optimizing rendering for specific
graphics cards. The results were impressive with the right hardware,
and total frustration with the wrong hardware.

AutoCAD was a better tool on DOS than on Windows, in my opinion.
The interface had to be kept minimal, and rendering speed was a primary
benchmark.
