This bus seems to be something like the ISA bus. I made here at BESSY 
somthing similar 13 years ago, a little 8-bit addr, 8bit data + some 
control bus and adapted this easily to an ISA bus. So an idea could be 
to use PC104 with ISA bus, create a adapter to your bus and than there 
is just the work to create an driver for the bus access and device 
support to the records. This PC104 boards are shurely more cheap as a 
self developed one, and there is not much work on the software side, I 
think.
