SASI device <-> PC ?

Has anyone here successfully interfaced a SASI device to a PC at the
I've got a few classic systems which use SASI (or not-quite-SCSI)
controllers to talk to SASI-ST506 bridge boards and from there to ST506
As has been documented many times in the past here, an ST506 drive has a
pretty tight relationship with its controller, and so hooking up the
drive to a different controller (say MFM controller in a PC) causes all
sorts of problems when it comes to backup.
Hence driving the SASI side of things (and preserving the drive/bridge
board relationship) would seem like a sensible move when it came to
backing up data. In theory data could then be restored to a replacement
drive if/when the original dies via the same method.
Presumably inventing a simple SASI board to hang off a PC parallel port
(say) is a lot easier than mucking around with the equivalent for floppy
drives - or is the data rate still likely too low to cause timeout
problems within the bridge board's firmware?
I've got several Acorn, Torch and RML machines which use bridge boards
and in most cases the tools needed to back up and restore data have long
since vanished off the face of the earth (my RML fileserver's a
particularly important one as it seems to be the only one left in the
