Me, too: the 2.04 OS kit for the A500 and A2000 was a "must have" item in Italy around 1991. But at the time it was out, it was too much expensive for my pockets... :-S > it is even possible to hack an A500 motherboard > and convert its expansion connector to a ZorroII slot... An external expansion box was made and sold around 1989/90 in Italy. It included a power supply, two floppy bays for 3.5", one for 5.25" and a couple of ZorroII slots. Interestingly enough, that box was designed to be placed _under_ the A500. The official explanation was that the expansion connection had to be kept as small as possible, to avoid signal lossage or interference. It wasn't a popular product, because a "real" 2000 was instead preferred and because the keyboard was placed in a non-ergonomical way. yo, RDO - This message was sent through the cbm-hackers mailing list.
