I have 'bus-space'd DC7085 driver for tty/wskbd/wsmouse in
[nisimura-pmax-wscons].  They were commited yesterday.  They are
in near-complete status, but never tested on real hardwares.

BTW, I started the research on IOASIC DMA assisted z85c30 driver found
in ULTRIX in order to replace scc/zs_ioasic.c of pmax/alpha.  There is
much more than DEC3000 hardware manaual tells about its circuit.
It's really painful to reverse-compile (to C) of tty device driver.
