not all 1m/20m 7300s came this way -- mine didn't.  it also had a
different motherboard -- patch wires and etch cuts instead of ram
jumpers.

i've never seen instructions posted for the ram board posted.
it can be upgraded, though; i did it.
the hardest part was finding the information on the 4 jumpers near the
face plate of the board -- i called *everybody* within at&t and
*noone* could tell me diddly!  the net finally enlightened me (;^>):
3 of the jumpers have 3 holes -- cut the etch and jump the center to
the other side.
