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 ...
Thanks,
Thorsten von Eicken
