Does anyone know the email address of Jeff Lavin? I was reading the Amazing Computing article on his I/O expansion board for the A1000/A2000 and I thought it was a shame that owners of the A3000 (I am one) cannot use this board. I would like to get the schematics for this board with the objective of designing a board that would plug into an A3000 slot and use all the drivers that are already written for this board. It does not seem like a difficult task. Basically, the exact addresses have to be decoded and timing requirements met. Although I have never designed expansion boards for the expansion slots of the Amiga, I have designed specific-purpose computers using the 68000 and 68020. So, if someone can get me the schematics, I would appreciate it. Also, if anyone know why this would be a difficult undertaking, I would also appreciate your input. The way I see it, two PALs for the address decoding and handshaking and the rest of the circuit would be the same as Jeff Lavine's. Thanks for any input. -- |******************************|*****************|********************| | Daniel A.
