Functionally the 65XE is identical to the 800XL.  Thus my first reaction
was to recommend any of the memory upgrades for the 800XL.  Unfortunately
things are not that easy:  in the 130XE some of the TTL circuits of the
800XL are replaced by a LSI circuit.  This affects the circuitry doing
the address multiplexing, which is where all the memory expansions
connect.  At best this would make it more messy to install any of
these upgrades.

The 130XE has an additional custom circuit to do the bank switching.  If
you can get 130XE schematics, it might be possible to wedge that additional
circuit and the extra memories onto the board.  (It is probably too much to
hope that Atari left space for all that on the circuit board, but I have
never seen the inside of a 65XE.

If you can get your hands on an 800XL, you could upgrade it instead, and
get a better keyboard in the bargain.

Question:  Does the XEGS use the same circuit board as the 65XE?
