[comp.unix.questions] Help with writing a UNIBUS device driver

ehrlich@psuvax1.UUCP (01/16/87)

If anyone has suggestion on where to find information on how to write a
UNIBUS device driver for BSD 4.3 UNIX I would appreciate hearing from you.
Section 6 in "Building Kernels with Config" is very terse and only refers
one to vaxuba/uba.c for further information.  "The UNIX I/O System" by
Dennis Ritchie is geared towards Version 7 with the note "still helpful
for those writing device drivers".  It is not clear to me if this is a
true statement.

Any pointers, help or suggestions would be appreciated.  Thanks in advance.
