The "+" used a Rev. 8 or 8a motherboard, 2.04 ROM, Super Denise, 2MB Agnus, RTC, and a few other bits'n'bobs. Also some A500's sold as "regular" A500's actually included the "+" motherboard due to a shortage. Although some of these were then further modified before sale to include less chip ram, or 1.3 Kickstart, or god-knows what manner of other modifications. It's a
cr@pshoot! But I've heard a lot of compatibilitiy issues with Rev. 5 motherboards, too. Wasn't there a thread on that somewhere?
