I've been on the lookout for an A3000 keyboard for the last few years, I even tried bidding on a couple on ebay only to lose out to crazy prices. Last week I ordered a 5 pin DIN > PS2 converter so I can use an A4000 keyboard. Later that day I'm digging through my storage for an A4000 keyboard (you're way ahead of me aren't you!) only to find I already had an A3000 keyboard in immaculate condition. Where'd that come from?! I love digging through my storage, it's like my own personal xmas LOL.
