Hi, Ive had a GVP A500-HD8+ for a while now, the first time I tested it my A500 would display a dark grey screen when it was connected, whether it was on or off. I bought a new hard drive, and upgraded the ROM from 4.13 to 4.15 and had no change. So finally I cleaned the contact pins on the A500's expansion port. Now booting the Amiga with it turned off causes it to display a black screen, and when it's on it displays the 'please isert' WorkBench disk screen, whether it's set to Autboot or not. I've tried it with and without RAM with the correct jumper configurations and with both hard drives, one which I'm sure has WB 1.3 installed and it's the same with both. Can some one please tell me there's some silly little thing I've missed? :-D
