It would be much, much easier to get a 50-pin drive, or even to use a 68pin scsi with adapter. There are still lots of them in circulation.

But there are situations in which I can understand that a solid state drive would be attractive, such as an old-school webserver running 24/7. Even there, though, the option of running the machine from a RAM drive using software like Maxima ought to be considered, along with a utility to spin down the HD. The silence would still be golden, and if you had plenty of RAM lying about and needing a use, it would be also be cheaper gold than the CF option.
