A PC with a SCSI card in 'Target Mode' as a replacement HDD?

A number of Adaptec chipsets/interfaces purportedly support target mode:

Q. Is target mode supported by Adaptec host adapters?

A. Target mode has been implemented in Adaptec's bus
mastering host adapter firmware for the AHA-154x, AHA-164x
and AHA-174x. However, our ASPI software managers do not
currently support target mode. To get target mode to work,
you would need to write your own host adapter software
manager, which is not a trivial effort. Adaptec cannot
provide you with any assistance in this effort. You can
request a techincal reference manual by calling our
Literature Hotline at 800-934-2766.

Just need to write your own software. Oh, boy!

Well, in a bit more on-topic mode, I decided to pull the cover and boards of the M-sys FFD SCSI Flash drive. I got a bit of a surprise.

Look at the photos and see how close the idea of a 'PC with a target-mode HBA' is to reality:

My Adtron S25CF SCSI-to-Compact Flash adapter is setup the same way. It has an AMD 80186 SOC, ROM, some RAM, and a standard PC SCSI adapter chip packed onto the board.
