        Bus Terminator 
 
        To build the bus terminator you will need an 86 pin wire wrap
edge connector, 20 10k resistors, 20 1k resistors and 20 .1 mf monolithic
caps. Basically you want to put a termination network on each of the 16
datalines plus on the four control lines, *AS, R/*W, *UDS, and *LDS. The
network looks like this:
                              10K

        86 pin connector
 
        Note: pins number at 1 on the top pin closest to the front of
the amiga, 2 underneath, 3 back on top next to 1 etc.
