Does anyone know if the TRS-80 Model 4 CPM Plus will operate with DSDD
drives?  This is the version sold by Radio Shack and does not come with
BIOS source.  My Model 4-P seems to support double sided drives, however
I don't want to open it up if it is hopeless.

Ps: And while I'm at it, RS dropped the TRS line like a hot rock and
neither support, nor released source of their CP/M BIOS, even though
their documentation says it comes with the package.  Their service is
usually excellent, but not for "stale" products.
