And the roms, too. But to find a working one is a different story. Remembering when I tried to use WHDLoad on my A4000 and all slaves were written for A1200. So A4000 3.1 Rom didn't work. After wading thru 10 or more A1200 kick images I finally found something that did work. Probably partly after my nagging to WHDLoad guys they finally began adapt for A4000, too (sigh of relief).
