This is a fascinating topic...
The prospect of installing a solid state disk system in an Amiga is
very cool and I've seen a few eBay links about here for SiliconTech
800mb Flash drives which run off a simple IDE interface.
There are also tips on Aminet on how to attach a PCMCIA card reader to
the Amiga.
Some even come in SCSI varieties with 6x card capability, 2x card
simultaneous use (on 2x SCSI IDs).
There should be a few files on Aminet on the correct way to format
these devices, I'm sure there was a proper mountfile included with one
too. I don't think it's quite the same as installing a hard disk.
Good luck and keep us in the know when you get it working properly. It
would be cool to have a Compact Flash slot to replace the DF0:!
:-D :-)
