> Forcing hand written should really not be necessary. It would be very cheap in terms of old computing hardware to set up a test room with old desktop PCs that have wired only NICs (with a network connection that goes to a switch in the same room with no uplink, connected to a decent size laser printer only), running something like lubuntu and libreoffice writer as a basic word processor.

Exams that only require paper, tables, and chairs can be done anywhere, and require minimal setup/set down, transport, or power, and no tech support.
