 I am a 4th year computer engineering student at the University
of New South Wales, doing a thesis project on transputers.
I wish to memory map some devices on to a transputer. What I would
like to know has anyone done this before and if so was there any 
problems in doing so. My other question are there any TRAM boards
that give full access to all the pins of the transputer. From what
I can see I will have to design my own board. Something I will 
happily do but would prefer not to. Even if some one allready has
designed their own board it would be a great help if I could get 
a copy of the circuit.

Any suggestions or comments about memory maped devices would be
greatly appreciated.

Thanks in advance

Ross M.

Check out the IMS B430 Prototyping TRAM. This has a T222 (16-bit and
easier to interface simple peripherals to than a T805), SRAM/EPROM
sockets and all the transputer signals brought to pads around the
periphery of a protoytyping matrix area. 

This board has been used to implement countless interfaces quickly
and simply, including A/D, D/A, CAN, fiber-optic and DSP coprocessors.
