The IWMless is a small and cheap module that goes into the place of an original but dead IWM of any Apple IIc or Liron card for the Apple IIe. As the tongue-in-cheek name implies, it's l e s s than a real, original IWM, so it can't be used in the Mac nor in the Apple IIgs, nor in the Apple IIc+. The technical reason is that the M8 / FAST modes of the original IWM are of no use with a 6502 CPU running at 1 MHz, so they were left out of the 'IWMless' which is meant only to repair Apple IIc and Liron cards, and nothing else. The advantage of trimming these excess functions away is to get to the finish line sooner and to be able to use a low end CPLD which costs less. Or are you one of these fools who want to pay more of your hard earned money to buy features you will never use ? (Oh, the consumer product industry l o v e s these fools - I don't).
