Looking for a board with multiple connected 18 series PICS

[johnt]

Does anyone know of a board with multiple 18 series PICS either connected to each other
or that could be easily modified to connect one or better still 2 8 bit ports in a bus
style configuration?

Ideally I'm looking for 5 PICs on a board but thats probably never been done so 2
or more may be of interest.

I havn't posted here for a few years (I'm officially retired) but I seem to remember
someone mentioning such a board a few years ago.

I'm looking for something I can do port to port experimentation with.

thanks
john.
