Viewing/using the cache of old IDE hard drives...

Is there a way you could remove the control/interface board from a hard drive and be able to view the 256-512K of cache as a "drive", like you would use a RAMdisk? I have several old HD's (200-500Mbytes), I have no real use for anymore (and they're way too slow) ad figure this would be an interesting "hack" to be able to use their tiny cache as a "micro drive", of sorts.

Remember, back in the 80's, when the Apple II's had 128K of RAM? Or the Mac 128? Or Atari 8-bit... or Commodore Amiga... or the Atari 520ST? There was a tine when 512K of RAM (and less) was PLENTY. And RAMdisks DID exist for those computers, too.

So, the cache size of an old HD isn't so impossible to imagine a use for... if you think back to the days when such amounts of RAM weren't thought of as so small... but massive!

Just having fun with some old drives that have outlived their "modern usefulness"

If it can be done...
