According to the label on the cart, its a 26-3029, one of the earlier 
FDC's.  It does not have a WD-1793  but the Fujitsu MB8877 for a brain.  
I haven't plugged it in in about 20 years, but it worked, no surprises, 
the last time I did.  But because the SC-II is a no halt, I always 
return to it.
