M7270 +5V at 1A    +12V at .22A
M8043 +5V at 1A    +12V at .25A  4 serial ports
M8027 +5V at 1.2A  +12V at .1A   2 serial ports, MXV11AC 32kb ram +Eprom

The M7270 is the LSI11/2 CPU (16bit address) and the MXV11 multifunction 
card are a near complete system on two cards. You would only need a Tu58
equiventlt on the secod serial port to boot or some disk (RXV21) to have
a system in three boards.
