Unfortunately, I do not have a newer machine, as I said before, but I did
the following, which those with new machines might try and help out here:
Went to DOS from the desktop, with nothing running or loaded beyond what
is always there (I keep an MS-DOS shortcut on my desktop, but no special
parameters set).
commanded MEM /D>E:\XYINFO\MEMCLEAN.TXT
That creates a text file with all the info generated by the mem /debug
command.
EXITed DOS, clicked on my Xy icon on the desktop to run the Xy pif and
load Xy.
Exit /nv from the command line.
MEM /D>e:\xyinfo\memxyld.txt
creating another text file showing what memory is like with Xy running.
Back in Xy, I called both files, ran compare on them, and here's what I
get:
With nothing loaded beyond Windows normal desktop (and the apps that will
load in the tray on startup), Mem /d reports the same as with Xy loaded
and shell to DOS except for the following:

Hope that is some help. I also checked my USB connection. Control panel
says it's using IRQ 11, I/O range E400-E417, but reports no memory usage
as such, nor is there anything like USB reported when I go to
System-->Memory.

By the by, can any Wise Person explain that weird entry under XMS:
Extended (XMS)   67,043,328       ?  132,997,120
The total is 67 Mb, MEM doesn't know how much is used, and 132 Mb are
free? That does not compute.
