hey

im trying to build my own mark - 8 (really old computer) but the only schematics i can find online are very old and some of the scan didn't finish properly so i cant read where different parts of the bus are spoussed to connect up with other parts of the circuit.

you can check out the schematics i've found online and see what im talking about at www.richie086.com/circuit1024.gif

check the top left hand corner where the 74123 flip flop is (labeled a-1 and a-2) and look where the output is.. i can tell its says somthing but i cant tell what it might say at all..

if anyone has this and/or more documentation on building a mark-8 please let me know! thanks!
