The center has a data/video projector, whiteboard, flip chart, OHP and TV/video for study purposes.
The final portion of the protocol defined by the OHP 1.2 specification is the client- and server-side shims.
The scope of the OHP also becomes unbounded since any service, not just hypermedia services, can be accessed via this mechanism.
There are OHP transparencies for use in explaining the system of recording results and also for the first card.
