thats another version of the C10 I have not seen before
a surface mount version of the old BOB with screw terminal blocks
rev1 without the 74LS00
C10 Rev 10
on the new C10 it looks like they have saved a 74ACT245 octal buffer by using one to buffer the 8 date lines instead of half of two IC's as on the old board
the circuit should be very like the one I posted in post 14
but now has an output status LED to the output enable
