Nope, sorry, wouldn't work.  This is a *1410*, not a 1401.  The 1410 
does usually have a hardware implementation of the 1401 buried inside - 
accessed via a switch on the console, but it is controlled 1410 style, 
via the 1415 console (including the selectric for displaying and 
modifying memory), not via lights and switches like the 1401.

However, the *technique* I used could be used to accomplish your goal, 
though you might need to multiplex the lights depending on how many 
connections it would take - for example, my Digilent board has 4 Pmod 
ports so only 32 pins of I/O.
