Well, unlike a lot of people, you have come to the right place!

Ooooh!  The one I used to use has only 32k...

: When he turns on the computer, he gets a screenful of

: autostart ROM).  Then he gets the system monitor prompt,
: an asterisk (*).

Good start...you understand this is normal.  Fantastic.

: He types a control character, then 3D0G.  (I'm sorry, but
: I forget what control character it was.  But he followed the

Ah.  Close, but that isn't quite right.  There are a few ways to start
this machine.  

*3D0G 
will not work unless DOS is active, since it is a DOS entry point. 
Instead of dumping you into BASIC the way it will once DOS is loaded. 
Instead, try:

*0G

There are a couple of other ways to do it as well.  For instance, if you
want to boot DOS, you can...

Call the Disk Controller entry point at $Cn00, i.e....

*C600G
[system boots from Slot 6]

You can issue the Monitor's equivalent to PR#6, which is a Ctrl-P, i.e....

*6^P
[system boots from Slot 6]

You can issue the Monitor's "jump to BASIC" command, which is Ctrl-B, i.e....

*^B
>PR#6
[system boots from Slot 6]

Note that once DOS is booted, should you find yourself in the Monitor, you
should return to Basic with a 3D0G.  Issuing a 0G will leave DOS disconnected.

Good luck!
