[comp.sys.mac.misc] RasterOps 208 troubles !

Hi Netters ;-)

Just an article for a friend of mine. He is leaving in Netherlands and recnetly
purchassed a RasterOps 204 video card from an American dealer (no names).
He's using a IIcx with 8 MB RAM, no HD and 2 SyQuest removables HDs with 
system 6.0.4 US. 

The problem is that after replacing the common Apple video board by the
RasterOps the screen flicks with slight horizontal lines going up and down
dimming and brightning sucessively. Very annoying you can't look at the
screen more than 10 sec.
When he plug again the Apple video card the screen is OK : sharp, fresh and  
crips, no more flick ! So, has everybody do in such case he sent back the
RasterOps board for a brand new one : "they" send him a RasterOps 208 but
unfortunately there's nothing to do the monitor driving him banana !

So please ! is there anybody from RasterOps on line ? What can we do in such
case (even hardware hacking is welcome) can it be the power frequency used
in Netherlands which is not compatible with the RasterOps video board ?
Strange problem waiting for not-so strange solutions !

Of course, if there's interrest about such case I'll summarize later ;-)
