[net.unix-wizards] Inquiry: ACC IF-11/1822

sdyer@bbncca.ARPA (Steve Dyer) (07/20/84)

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.

From the horse's mouth itself, ACC, comes the answer: the IF-11/1822 was a
special unit produced for a US government client, and is not generally
available for sale, not is it particularly desirable in place of the
LH/DH-11, for it is quite slow.  The only advantage would seem to be the
single board design.

My order for an LH/DH-11 went in today...
