Installing IBM OS/2 1.0 in a VirtualBox VM

MS LAN Manager NDDK Anyone?

For R&D purposes, I would very much like to get my hands on the circa 1991 Microsoft LAN Manager Network Device Driver Kit which was meant to support the development of NDIS 2.0 drivers. While it is obvious that some … Continue reading
