I received mine in the mail today and tested with my A500 - it works perfectly!
RGB to VGA AdapterI also picked up a RGB to 15-pin female adapter from Amigakit.
Next, I had to use a 15pin female to male vga adapter from a local pc shop so it could hook right to the Ambery converter box.
BTW, the Ambery converter comes with vga to Component video cable, so you could hook you Amiga to a big screen tv!
Now my Amiga works great on a 15" MAG CRT I have had a while... once I get some more pennies saved up, it is time for a LCD for my A500!
Thanks
