Yes, DEC made an IBM channel interface called the DX11B.  I have 3 of
them on various PDP-11 (Unibus) systems.  You can still get them on the
used market.  Software support is a problem, however.  We wrote all
our own software for it.

DEC also makes a follow-on box to the DX11B called the KDX11.  It's
supposed to be smaller, faster, etc.  but it's only marketed overseas
through World Trade.  It's not marketed in U.S., but you can get it
if you really want it and can do self support.

If you have a Q-bus system, there is a channel interface available
from AUSCOM (formerly Austin Communications) distributed through KMW
Systems Corporation.  I have 2 of those.  They have a "library" of
software subroutines and some stuff to let you drive DMA graphics
devices. I talked to KMW at Interface '86 and they are developing and
preparing to market a system including software to do TCP/IP on
Ethernet attached to IBM channel, joining battle with Spartacus and
Wiscnet.
