I agree. It should at least help getting the people with so far unsupported
machines started. It's less frustrating if you at least see something on
the screen when you start hacking ;-).

Hmmm, we can easily determine if the machine has a TC option - AFAIK the only
machines without TC support were the 2100/3100 and that weird Q-Bus based
DECstation (5100 ?).
But what about the people who are using a graphics console/keyboard ? They
probably prefer to use prom console instead of attaching a terminal, so
we could already determine which console to use based on the (os)console
environment variable ... (And it's finally time for me to merge my
DS2100/3100 graphics console code and bring it up to date with the vfb code !)
