Recently forum member mikesmith alerted me of an eBay seller selling a batch of IP940 boards at quite reasonable price of $50 with free shipping. So I purchased two and worked with mikesmith to boot up the board. IP940 is made by Perceptics; it is a VME mezzanine board consists of 33MHz 68040, 12 meg DRAM and 2 meg of flash. It needs a baseboard to provide power and I/O via 4x32 Euro-style connector. I do not have such baseboard, so I prototyped one and later build a pc board baseboard. This is rev0 of IP940 baseboard. It uses EPM7128S CPLD as glue logic supporting quad-serial OX16C954, compact flash, and 8-bit I/O expansion port. Rev0 pc board is working, here is its homepage.

Rev1 of IP940 baseboard should be the same dimension as the IP940 (6"x4.5") and have video and PS2 supports; network support is also desirable, beyond that, I'm not not sure what functions should be added. The design files are open to all so anyone interested can add your own.
