Inquiry: ACC IF-11/1822

[Steve Dyer]

Does anyone out there have very much knowledge or experience with the
new ACC UNIBUS ARPAnet/1822 interface called the "IF-11/1822"?
Note this is NOT their HDH interface.

It would appear to be one of their UMC/Z80 boards with special hardware
to perform both the logical and physical 1822 protocols.  It is physically
much smaller than the older LH/DH-11, taking up two hex slots in the
UNIBUS backplane, but without the 19" washing machine which often requires
another VAX cabinet.

Can it run as fast as a LH/DH-11 between a host and a C/30?  Is it reliable?
Has anyone written a 4.[12] network driver for it yet?  Its size alone makes
it sound attractive, if it works as well as the old, faithful LH/DH-11.
