[b]Terminators for Enhanced video cards[/b] from Brad Parker (out among the flat cornfields of Iowa)
 
     The terminator requires three 75 ohm 1/4 watt resistors. As 75 ohms can be difficult at times to find, rest easy in knowing that the originals have a 20% tolerance, so any 5% tolerance or better resistor with an impedance between 63 and 100 ohms should work.
 
     The resistors are wired in parallel between each color's drive pin and it's respective ground. In addition, the terminator keys the monitor ID to 0 by having a jumper between the 0 ID pin and digital ground. (Monitor Presence Detect ID=0); which together with opens on Pins 4, 12, and 15 (MPDID 1, 2, and 3) ensures that the system thinks an 8512 or 8513 (640x480 analog color only) monitor is attached.
 
     Use a 15 pin male VGA connector and hood. The component values are as follows: R1-R3 75 ohm 20% 1/4 watt resistor J1 Insulated 24 gauge single conductor wire  
 
        Connect as follows:  
       Pin                Pin  
         1 ----^v^v^v^v---- 6  
         2 ----^v^v^v^v---- 7  
         3 ----^v^v^v^v---- 8  
        10 ---------------- 11 (shorted, in words)  
 
     Note the original unit has shrink tubing on the resistor leads-Not a bad idea.  An alternate technique would be to just plug in any old monitor on the base video VGA output. Of course that takes up a bit of physical desktop.
