TSS/8 with modern disks?

Seems  like a  ssd  would  make an ideal    fixed head  replacement if it 
has  to swap swap swap all   the  time?

Or the RF08/RS08 --  luxurious compared to a DF32/DS32!

A zillion years ago, the DECUS library had a TSS/8 hack to  make it run
on an RK05 (as the only disk I mean -- later TSS/8s already  supported RKs
as data disks, unless I've gone senile).  No idea how  they managed that --
the wordiness of the DF/RF controllers penetrates deep  into TSS/8's soul.
Maybe RFILE/WFILE weren't done compatibly with vanilla  TSS/8?  Dunno.
