Yes, just checked, ls still works here, with the usual options (see below for proof). Not sure where I got it from, and unfortunately I don't seem to have a Windows 'where', but I think it's the old one (file date 1990) in C:\DOS\BIN

I copied several "UNIX" programs to this Windows PC* when I bought it 12 years ago and they're still there (later I added Cygwin too).

* Yes of course it's been updated since - 2 new motherboards, 3 replacement CPUs, new disks, more RAM, even a new case case, ...
