The drivers are recreated from existing object and selfloading tapes and
assembled with the DAP16 assembler under simh H316 simulator.

The "drivers" directory contains symblic links to the driver object files in 
the "details" directory. The "details" directory also contains for each 
available driver:
- a txt file	text file of the driver (unix)
- a src file    source file (txt file converted to DDPx16 ASCII record format)
- a lst file    file with the assembled listing (unix text file)

The drivers are certainly not tested in detail; some simple tests are done 
on most of them. The testprogram/data which was used for the magtape drivers
is available in the directory "test".

The drivers are collected in 3 libraries:
-iolib.lib	contains all available drivers
-biolib.lib	contains the tty, hsr, ptp and lpt drivers
-asrlib.lib     cantains the tty drivers only

The libs do not contain the dummy driver routine. Dummy routines are 
meant to satisfy driver entry points required by the linker, in case 
the full driver should not (or can not) be linked. 
If for instance an object file requests to link with the cardreader 
input driver I$CA, and that driver is not available, the dummy driver 
is linked for the cardreader driver. The dummy driver is the last
object file to be linked.
The dummy driver is not part of the libraries because system 
applications like the assembler and fortran compiler use their own
dummy driver. The dummy driver in the driver directory can be used
for non-system applications.
