SDX does have a config.sys file but I don't know the MSDOS config file so I can't say just how "close" they are. As for the cart line...forget it....the SDX does not like being played with. I am not sure how the on/off function is accomplished, but it is apparently compatible with other carts (so you could put BASIC XE on top of EXPRESS, on top of DIAMOND, on top of SDX, on top of the RTIME8 and they would all work).
