No., I don't think I was.  But I specifically was refering to application type
software.  If I wrote device drivers I'm sure I'd have a different view.

Again, application programs don't commonly do that.  They should call APIs
instead.  I've had no troubles with 16-bit APIs from any of my applications.

And all the hardware for a 10-year AS/400 can be attached to a new iSeries box?

All of my modems from that era work fine, albeit perhaps a little on the slow
side.  And the communications software I wrote back then still runs fine too.
But since it was written prior to Win95, it doesn't share the modem.  It wants
exclusive access to the COMx port containing the modem, and it initializes and
dials it directly -- not via TAPI.

I didn't write device drivers.  I wrote application software, using statements
available in the language and using calls to external 16-bit APIs in various
DLLs when the language did not have native support for what I needed.

And those still run fine under every verson of Windows since (well, "fine"
insomuch as Windows runs "fine", which is another matter entirely...).
