It’d be in the zip file, assuming someone didn’t clip it.

Was there ever a license included with HIMEM.SYS 2.06?

It’s from several years ago (4?).

Anyways what you want is this one:

https://github.com/neozeed/GW-BASIC-tkchia-devel

Which is updated to work

I thought it was well known, but I’d added it to github a while back

https://github.com/neozeed/himem.sys-2.06

It’s _out_ there as part of the specification disk, but hasn’t been relicensed.

DOSSHELL is also missing.

I can’t imagine a scenario where vmware/hyper-v/kvm wouldn’t suffice. Even when it was ‘current’ NT 4 terminal server is how I delt with needing to run Win16 stuff, as you could detach it and let it run in the background.

They are going to drop real/286/v86 modes soon enough anyways, so it’ll all be moot.
