I am thinking about building a small 68020 board with nothing but CPU, some 32bit wide RAM and a high-speed link to the outside world. _ I intend to use 256k dynamic RAM chips but would like to be able to upgrade to 1M chips when they are available. Does anyone know if this can be done ( i.e. what is [or will be?] the pin-out of the 1M chips ). _ The high-speed link is supposed to connect the 68020 to some PC ( amiga? ) to get I/O done ( disk, display, keyboard .. ). Does anyone have an idea what I could use. I thought a 68230 ( parallel interface 16bit bidirectional with handshake / 24 bit timer ) would be quite nice especially because of the timer I get too. Is DMA on the 020 necessary? I have the feeling that the speed increase wouldn't be fantastic and that the other side anyhow couldn't follow. I would be very grateful to anyone willing to waste his time sending me his thoughts ...
