Yes, there is, but it tends to be a fairly constant time period unless
there is a key entered.  The jitter problem was real strange.  It wasn't
noticible at 8 Mhz, and I NEVER saw it on the Z-80 version.  I admit that
blaming it on refresh was perhaps grabbing at straws.  It was never a really
obnoxious problem, but I did spend an inordinant amount of  time trying to 
figure it out..... any OTHER ideas?
