That's the plan.

I have a 1.2B INSTALL config file that should produce an INSTALL
kernel that boots on either aha or bha machines. It's  just waiting
for testing and approval from the i386 portmasters to commit.

If you have a machine  with an AHA-1542 to test it on, that would be great.

In fact, the ideal test is a machine with both a 1542 AHA *and*
an ISA buslogic, but since NetBSD didn't support that  combination,
it might be hard to find...
