Charlie please help if u can

ok ive posted a few posts about my ps2 to find out what version it is,only got one answer but that wasnt convincing so if i cant find out ill sell it and buy a new one ive already started looking what the shops are selling and so far they are all 30002 r which i think is ver 5.
So my question to u is if u dont know how to tell the difference between ver 1 2 3 pal can u tell me if buying a version 5 will be ok for a major chip,what i read at origa is that the ver 5 has some trouble with there chip,at link-sang there neo 4 doesnt say if it will work in a ver 5,and cant find a messiah.
so any help in what i should do would be great thanks for any help.
recent news i just brought a 30002 8 screws on the botton so i think its a ver 4 so if u can tell me what i should do from here im thinking the origa an then one day if i get the messiah ill change it,so if u can give your thoughts thanks
