on my 8032 motherboard, I have a strange cursor

blinking 2x2 checker board...

when I replace the ram and rom (except $E000)  with tynemouth ram/rom I 
get the same result

the $E000 is brand new and made with a 28c16 containing Steve's NTSC 
editor...


I'm convinced the problem comes from the crtc or the circuitry producing 
the video signal

any idea ?


thanks
