I read that Qrst was just a file format. To quote The
QRST disc image
format was used by Compaq to distribute disk images of diagnostic
software. The file QRST.EXE or QRST5.EXE would be supplied with the disc
images to write them to a floppy drive.
-So do you have the QRST programs available?
Yes. However the QRST program is a 16 bit app that requires physical
access to a real floppy controller. Thus it cannot work on a Windows 10
system with DOSBOX as the floppy is USB and I don't think DOSBOX
emulates a true floppy interface at the BIOS level.
Modern archive tools like 7zip do not appear to have support for QRST
format. It's compressed in some odd way, so it can't just be dd'ed to a
floppy sector by sector.
Never dull.
