floppy-emulator

[BigWumpus]

Hello,

I want to build a floppy-emulator in order to throw away the floppys and the drives because of hardware-failures and to use SD-cards or so.

Has anybody realized such interfaces ?

If you're using XP, all you would need would be a $25 USB card adapter. The cards show up as additional drives on your PC. Just drag the data over from the floppy and throw your A Drive out the window.

Hi,

Teac Floppy specifications:

You are going to spend lots of time to achieve that.
By the time you complete this project, the motherboard
manufacturers will have removed the floppy disk controller
from the motherboards!

Good luck!

Mööp...

This computers don't have any PCI-Ports or any other useable ports...

They are using DOS

Hi,

Does it boot from an internal hard disk or from the floppy disk?
If it boots from the floppy, do you have a 40 pin IDE connector on the motherboard?

CPU version? (386, 486, Pentium).

Best regards,

Hello,

I think there are very old prozessors,
there is no HD, USB ...

Hi,

If you have a IDE Standard 40 pin connector on the motherboard you can use that:

Compact Flash cards use Flash Memory. Flash Memory has a limited number of Erase/Write cycles
~300,000. The controller in the Compact Flash card does wear leveling by spreading out the writes
amongst various 'sectors' in the card to prevent premature wearout of a sector.
Here's a link to the originator of the CF card that discusses how they 'wear level' the flash memory to
optimize card life: http://www.sandisk.com/pdf/oem/WPaperWearLevelv1.0.pdf
Digital cameras write to Compact Flash cards to store their photos. However, if you were to place a
pagefile or swapfile on the Compact Flash card, the intense write activity would very quickly exhaust the
life of the card.

Best regards,

You can buy them on eBay for $30 up, they sell them to replace floppys on cnc machines, and work with DOS. I put one in my FADAL, only after that did I realize I didn't know how to access the floppy on it LOL. I was able to access the files from dos though while testing it on a PC
EDIT: They access flash drives not SD

I not have opening inside those ebay type emulators,how many stuff they having inside ?, but this one here is as possible simply, and less of components means also less of price too. Even ahelet type floppy emulator can work wiht no segment and no buttons connected, just one sc card becomes one floppy. Same code, nothing needed change, you can easy make it reduced way if you need only one floppy in one sd card.
