ACA500 Problems

[apsturk]

Hello all,
I have 2 A500's and a few weeks ago got an ACA500. Both computers are NTSC and I have not opended them so I don't know the Rev #.  Amiga 500 #1 after putting the ACA500 into to side car slot,  will not power on. Amiga 500 #2 will power on but I just get a white screen. I left the jumper as sent from amigakit and also moved it around and no change. I have run out of ideas other than something I just read that said that NTSC Amiga 500's are not supported. Is that true (never saw that before, hope I did not wast my $$) and any ideas. Thank

Well I will check the Rev # and see from there. I was unaware that Rev 5 NTSC bords are not supported when I sent $$. Your correct the most common bord is the US??  Will there be a film/flash update that will correct this?
