Yes, I think it takes everyone a little searching to get everything
together to try macbsd. I know it took me a while.
But to answer a few of your questions...

I think this deserves a little clarification. From watching this group, it
seems there are two things people call "ADB" type problems:
1. ADB doesn't work AT ALL on some machines.
2. Everything hangs after typing a few characters.
The real ADB problem is the first one. On my IIsi at home, my ADB doesn't work
at all, so I log in over the serial line. I believe the second thing is due
to a race condition in the kernel that occurs when the screen scrolls.

The MAC ROM Glue is an effort to use the MAC ROM routines to do the ADB
polling instead of accessing the hardware directly. If you are running on
a IIx, I don't think you should need the MRG kernel, since ADB works on IIx
machines. You mentioned that you could use the 'screen' program, right? Well,
if you can use the screen program and your normal keyboard, then your
ADB works. You are experiencing the race condition, I think.

I agree. But remember that all of this is voluntary. The Alice Group has
done an extraordinary job at this. I am still amazed that I can do as much
as I can on my Mac IIsi! The main point here is that some of the people
who have been working on this have real jobs now, and can't devote as much
time to this as they did before. I'm sure everyone would welcome a new
updated FAQ. Your outline here could be a start. Want to volunteer your

The 'race' condition doesn't appear right away. You can usually type a
few lines before it hangs. But if you can type at all from your
extended keyboard and see it on the screen, the ADB code for your machine
works. I can't get any keyboard response.

Here is what I do: I've got a modem cable for my mac. I've got a modem cable
for my cranky old 8088 PC. I use a null modem and hook them together. I use
some ancient version of procomm and the thing acts like a dumb terminal. Use
9600 baud, 7 bits, even parity, 1 stop bit. You can use 9600, 8, N, 1 also,
and the boot messages will show up, but the login prompt will be send in
9600, 7, E, 1 mode. Once you login, however, everything looks ok.
As you might imagine, and I've had bad results using serial console AND
having a login set up for the serial line. I suggest doing one or the other.
Clicking on the serial console button of the booter sends everything out the
serial port. If you don't use the serial console, you'll see the boot messages
on your screen (hopefully) and the login prompt only will appear over the
serial line. To turn the login on the serial line on or off, edit
the /etc/ttys file. I hope this helps.

Time to learn ed! ;-)

You may not be far off. I _think_ that they needed to time the mac 1.0 release
with the release of 1.0 on all the other platforms, so some things still
were not finalized.
Regardless, I think the effort so far has been great on developing this.
More people are needed to improve on it's current condition. You can contact
one of the Alice Group if anyone can offer their services. (Brad and Allen
seem to post to this group most often. They can probably tell you where your
time and effort could be used.)
