Wonder if it will work with Win 8.1...

"To further simplify the buck regulator design procedure, National Semiconductor is making available computer design software to be used with the SIMPLE SWITCHER line of switching regulators. Switchers Made Simple(Version 3.3) is available on a (3 1⁄2") diskette for IBM compatible computers from a National Semiconductor sales office in your area."

 

3 1/2" diskette could be a clue!
N.S. maybe able to answer if you shoot a question to support?
Max.

 

Maybe someone senile wrote that?

 

Shucks. My PC only has a 5 1/4" drive which I recently installed to replace the 8".

 

It has been there for ages + was never updated. There is no diskette drive port anymore on most new mainboards, sometimes theres still a IDE port, but if not, you could use a USB adapter (these work fine for all IDE drives).

There are even USB floppy drives. Floppies are however prone to get damaged by shipping, from static charges either happening in the postal sorting or on the plane, and X-raying wont be good to them either I guess.

Same like VHS tapes, there are few to none advantages to using floppies anymore, so, nobody is still buying them, and so, they arent made anymore. The safety of data on floppy disks is actually quite low- they can loose bits for no obvious reason.

If the program is based on MSDOS text mode, it very likely still can be used. If it is using graphics mode, you need a Windows edition that supports graphic mode. Some programs also use DMPI EMS XMS and all the like, and are prone to not working, or crashing at some stage or crashing randomly for no reason.

They have a designWorkbench - Flash version.
