Replacements for ST-406/ST-512 drives

[Kelly Leavitt]

OK, here is something I have not been able to find. Are there any
replacements out there for ST-406 or ST-512 interface hard drives. I know
there is a lot of NOS and other old pulls floating around, but is there
anything that would drop in and let me use a CF or similar device? I have
several old machines here running XENIX, and would like to try to find
something. I can see the day when even the old stock out there just doesn't
run any more.

How hard would it be to develop something like this?

Thanks,
Kelly
