Just a quick note to confirm that my WinNT port of the SNNS kernel works on
Win95.
Tomasz Chady has confirmed this today. Thanks Tomasz.
I've attached a short information note regarding the port. Please note:
this port is the kernel only. That is, no UI.
If anyone out there would like the code and "snns.dll" e-mailed to them,
please let me know.
Cheers,
matt.
