   Well... I think we can discuss TRS-80 stuff in this brach of the thread :-)   
      
   The card plugs directly onto the graphics option pins, has a screw that   
   replaces the middle left side screw of the motherboard and there is also   
   a clip that takes a signal from U13.2 (IOUT_LOW) and the jumper E14-E15   
   has to be removed.   
      
   It works very well. Did the test with success. Some nice images there.   
   Now it is drawing the "hat" (radial sinus thingy) in fake 3D, quite   
   traditional. During the test there was an image of a sin(r)/r in what   
   looked like real 3D, like the one I made (some years earlier).   
      
   BTW (question)   
      
   I had to use the Model III to copy the floppy so the Model III was on   
   and out of envy it blew a capacitor. Smoke came out of the top and it   
   was that typical sour smell (good thing my wife isn't at home) so I   
   opened it too expecting to see something nasty but no; it looks just as   
   before and works. Anyone have any idea of how to identify the capacitor   
   when visual inspection doesn't work? The smell seems to come from the   
   powersuplies, I suspect the one that goes in behind the floppy tower...   
   The smoke came out of the larger grille area so not from the   
   motherboard. I'll check the power with an oscilloscope to see if there   
   is any ripple but is there anything more to do. There is now an empty   
   electrolytic capacitor somewhere there.
