Hmm. The ONLY combination of this that will work is: Combo with 1M in any slot.
It will take up "memory slots" 0 and 1 no matter where you plug it in. Plug the
512K card in slot 3 (the one next to the serial port). It IS sensitive to
physical slot versus memory slot! The best solution is to put another 512K on
the Combo Board and do my mod to the 512K card to address it into memory slot
3 (the 4th one). This makes the card slot insensitive.
