Description

IGNORE SHIPPING COSTS, ITEMS SHIPPED AT ACTUAL COST. REFUNDS WILL BE ISSUED WHEN NECESSARY.
PLEASE ALL THE WAY DOWN, IMPORTANT INFORMATION
This listing is for a set of IBM DOS 5.0 disks and booklet.
These are 720k diskettes. (A 1.44 drive will *usually* read a 720k disk )
I opened the plastic to take pictures of these items, so they are in great condition.
All disks were tested, and you can see them being shown working.
Items will be very carefully and safely packaged and shipped.
Check my feedback.
*****************************************************
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.)
**************************************************************
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 )
