It is a LUCAS/FRANCES-based 500.  Sorry, I did not mean to get anybody's 
hopes up.

By the way, I have noticed that my 1084, which often suffers from the 
interlace fuzzies, seems to actually prefer PAL mode;  I have not seen
any trace of the fuzzies in PAL mode.  Maybe it prefers the slower
scan rate.  So while the flickering is a bit worse in PAL mode than
in NTSC mode, PAL mode does provide a sharper picture and a bigger screen
(I'm getting 704x564 pixels with morerows).

Of course, with PAL mode and morerows, you could get a 704x282 non-interlaced
screen as well, which might be a reasonable compromise for those who just
can't stand the flicker.
