Actaully it's CTL-ALT-INS and that brings up the MFM-200 "Monitor" program,
which is essentially the CMOS setup and utilities. The ones you have are loaded
with memory since they have RAM addon cards but the base memory is only 512k and
is soldered to the processor card.

The Zenith 3 way monitors are only good in amber/green for text. Windows
probably wasn't installed since either no one knew how to get Win 3.x to work in
CGA mode or just because it's a Mac-like (old Mac) black and white "two color"
mode. I just picked up one of the ones I originally sold on a trade-in for a 486
last night, still kicking. It has a Seagate ST-251-1 42mb HDD with MS-DOS 6.22,
Windows 3.11 in Hercules mode, mouse, printer, etc. It was used in a business
but they wanted to use a Win95 program so the 486 was the next logical step and
still save $$$.

Too bad they're so heavy to ship or I'd offer it for sale here.
