Doh! That was supposed to read "many", not "any"... I have a largish
(60MB?) MFM drive in a PS/2 Model 30 here.

I won't dispute that the XT2190 could be formatted to 159MB, but I'm
reasonably certain on a DEC controller like an RQDX3, you got 154MB
after the factory badblock table, etc., was taken away at low-level
I did not know there was an RLL drive that large, though. I figured
the world had moved on to ESDI and 5.25" SMD drives by then and
stopped worrying about RLL.
