I've noticed that RMS has support for DAP devices. Such a device
has the dev$m_dap bit set, and is assumed to "speak" DAP protocol,
though without DECnet. RMS therefore fakes it out and acts as if
it were talking to a network FAL connection, sending and expecting
DAP packets from the device for all I/O (which gives the ability
to do stuff like claim the disk is stream-only...). Thus a neat
hack like translating some other protocol to/from DAP works well,
and it seems well suited to making non-ods2 file structures "look like"
ods2. This is a neat hack.
   Are there any PD or freely distributable sources for docs of the 
DAP protocol around? I know the protocol itself was released by
DEC to the public domain (in the '70s) but am wondering if the only
description to be had must be bought from Digital.
   Also, isn't it wonderful to have listings CDs?? ;-)
