BTW I am  getting frequent short data dropouts in the output display.  I 
have  tracked that down to the possibility that I don't have enough RAM

better.



Hi Brett,

 
    This is most likely to be due to timing problems or  to data rate 
settings near critical values. You can also get it if the processor  tries to 
switch RAM. Check the free RAM and check that the data rates are within  
specification. The AS-1s have these problems due to a PZT timing ''crystal'' on  
the processor board in place of quartz.
