Thanks for the links, Tony.

Yeah, I've been aware of those things, but they're all just a bit more 
than I can afford to spend on something like that, especially when I 
have no real certainty that they'll work for my application. I've tried 
to use cheap SATA/IDE adapters on commodity PC hardware and found them 
completely useless (though cheap IDE/USB adapters have always worked 
great for me.)  I guess that experience has soured my outlook on the 
whole hard drive adapter genre, especially seeing as SATA/IDE is 
ostensibly just a physical adapter, requiring no change to the 
protocol.  If even that doesn't work as advertised, why should I expect 
a more complicated SCSI to SATA/IDE translation to work better?

Arguably, if I spent real money I might expect a better result than I 
would get with a $15.99 adapter, but my experience with cheap IDE/USB 
adapters has always been positive, (so cheap doesn't always equal crap) 
and my experience with hard drive interface adapters (all cheap, but 
different brands) has been universally terrible.  I get that there isn't 
nearly the market for SCSI adapters as for IDE/SATA, hence the price 
difference.  But the specialty nature of the product doesn't enhance my 
confidence that it'll work for me. On the contrary, it increases my 
concern that they may not have been tested on a wide variety of 
equipment, and may not work on the MM/1 or the Amiga.

At this point I may still have a few cruddy 66MHz PPC macs I can 
scavenge SCSI drives from without paying $150.  Probably by the time I'm 
forced to get one of those adapter boards they won't be available 
anymore.  If the N8VEM guys are designing their own adapter, that at 
least provides the possibility that some kind of adapter could be built 
in the future.  If I'm going to throw money at a HD adapter that I'm not 
sure will work, I guess I would rather throw it at something designed 
and built by and for hobbyists who care about the computers themselves 
and might be willing to help get it working.

Does anybody have any direct experience with these SCSI/IDE/CF adapters?
