I-O DATA IDSC21-E SCSI-IDE adapter and LC 475

Try it and let us know. Several members of the list have used the Acard 7720U SCSI-IDE adapter in similar applications with success, so I expect your card will work too.

I will try it, as soon as I know which jumper settings to use. I have the file which explains it, but I'm either too dumb or too lazy to work it out. :I

The file with the jumper settings is here:

I'm hosting that file because I currently have 10 of those boards in use in various machines (mostly macs, a few suns, hp, etc.) all connected to ide-cf adapters. I'm not a big fan of ye olde spinning, noisy media. If you have any specific questions, I'll do my best to answer them. A general writeup of my initial experiments is here: http://synack.net/~bbraun/ridsce.html

id like to try and find one of these for myself to try it out.

Does anybody know where to find those (or the equivalent Acard 7720U) for cheap, or not so expensive? The Acard is still sold for around $150. Some appear on eBay from time to time, but also very expensive.

I've been looking for a long time for one, or even better for a 2.5'' SCSI-CF adapter (think PowerBook).

They seem to have gotten quite expensive. A little over a year ago, I bought 10 of these for about $100 off of ebay. You can still find them on ebay, but seem to be significantly more expensive. I don't know of a cheaper source though.
