I found an XE base unit at the Salvation Army today at lunch with no power supply. I'm having a hard time finding specs for it. Is there any other power supply that'll work for it? By chance I also happened to find an Atari 800XL at lunch today w/ PS and hook-ups. BTW there was also dual Atari floppy drives there for $6 CAN would ahve grabbed them too but I had too much stuff to carry already. Are they worth a trip back?
