   I have a working Tandy 25-1000 + Tandy composite monitor. The base system   
   (128K) works fine, however it came with a memory + rtc expansion card. When   
   the card is plugged in, the system still seems to boot (there is a beep and a   
   floppy seek) but the    
   composite video output is blank.    
      
   It initially came with the expansion card plugged in, so I'm assuming it must   
   have worked altogether at some stage, although it hadn't been turned on for   
   many years prior to when I turned it on. I replaced the RTC battery but still   
   no go. Is there a    
   known issue with expansion cards and the video? Perhaps some overlap or   
   conflict with video memory?
