Well, I haven't had time to play with it to see what it will do but
a long time ago I downloaded a zip file of Unix utilities ported to
Windows that includes the bash shell. A quick check (invoking echo, ls
and exit) shows that it *does* run on my Windows 98 machine:

c:\utils\unix>ver

4DOS 7.50 (Win98) DOS 7.10

c:\utils\unix>bash
bash$ echo $PATH $COMSPEC
C:/UTILS;C:/UTILS/UNIX;C:/WINDOWS;C:/WINDOWS/COMMAND C:\4D\4DOS.COM
bash$ ls ba*.*
bash.exe
bash$ exit
exit

c:\utils\unix>

The file size of that copy of bash.exe is 403968 bytes.

It's part of a collection of Unix utilities ported to DOS that I
downloaded a long time ago (as a single 1023772-byte *.zip file).
Unfortunately, I'm not sure what system I downloaded it from and I
can't Google for the zip filename as I was forced to truncate it to a
DOS-compatable 8.3 filename to download it with my DOS-based terminal
program.

Several archives of Unix ports to DOS in my bookmarks files appear
to have been visited by the 404 Fairy so I can't tell if they were
the original source or not. (Simtel appears to have deleted *all*
of the gnu utilities they used to have archived and a Google search
for native (not Cygwin) ports of bash to DOS and /or Windows finds
a lot of references but most point to the extinct Simtel archives.)

Garbo only has a port of the Korn shell (ms_sh23b.zip), not bash:
