First, make sure the connection is good between the expansion
interface and the keyboard.  Without that connection, the
processor never knows the extra memory, drives, and/or RS232
are there.

Second, you're not accidentally holding the BREAK key when you
power on, are you?  That's the way to force the system into
BASIC on startup, even with a disk system and the drives turned
on.

The Model I is a classic system indeed (hey, it even has a
detached keyboard! :) ), and I wish you all the best in
getting it going.
