I am curious if anyone has successfully done this. I have a few XT-IDE controllers laying around (Seagate ST11R, e.g.) Before I go building a bunch of Lo-Tech cards, I would like to see if I can use my existing controller cards first. Thanks.

A Seagate ST11R is *not* an IDE card -- it's MFM/RLL. :-)

Also noticed I referenced an RLL controller card; this makes me wonder if there are industrial flash devices that might be compatible with RLL & MFM controllers. Not that this might be the best solution, mostly just curious.

They are IDE/ATAPI.

Generally no, but I believe there was a project for an MFM emulator, but it's certainly not something you can buy off ebay and just jam in.
Would be easier to just buy/build an XT-CF or XT-IDE card itself if you have the luxury of being able to fit expansion cards.

The MFM project is alive an well...

well I hope so as I have yet to build mine, but its a complex product and really only necessary for cases where you can't replace the controller. Much cheaper and simpler to replace the controller board.

But that board is for a DEC. Is there a version for the PC ISA BUS?

Its a generic MFM disk. Check the compatibility list

for tested systems. No IBM there but pretty sure it would work
