*****************************************************
Test procedures:
I built a Four Floppy computer (360k, 720k, 1.2M and 1.44M ) with CD-ROM drive back in the 90's. I have a special four floppy drive controller in a 486DX4-100 computer that I built for "special purposes". I found out a long time ago that Windows 3.1 would support four floppy drives. (Win95 and above WILL NOT). This allows me to easily "read" disks a lot faster than entering DOS commands. (Plus, I can copy programs from any media, including CD-ROM drives to any size media I want. I could even copy to and from 2.88 drives back when I had PS/2 machines by networking them.) You can see a picture of the computer in the photos.
**************************************************************
All disks are "looked at"
to prevent any disputes
about any disks that can't be read. This is time consuming, but important when selling old software. If I run across any disk that I can't read, I don't list it.
I will show disks being read by Windows 3.1 File Manager if space allows. Naturally, I can't show all disks if there are too many,
but they will ALL BE TESTED.
I have lots of other vintage software listed, and will be listing more very soon ! Please check my other items, this is good stuff and all tested.

I no longer like to  lose money shipping items, so I use the USPS calculator and issue refunds  when necessary ( almost always )
