Amiga 3000 daughterboard rev 5 on revision 9.3 motherboard

[hishamk]

In the 3000, is it possible to use a rev 5 daughterboard on a revision 9.3?

What are the problems associated with rev 5 that would make one want to use a rev 7 or higher daughterboard?

Thanks!

Yes, it's possible.

Interesting. I suppose a rev 5 daughterboard in a 9.3 motherboard would mean that somewhere someone swapped a rev 7.1 db with a rev 5? Or did they actually ship rev 5's with some 9.3 motherboards?

As for the rev 7 daughterboard, the site indicated that they were never released to users, but there are rev 7's out in the wild. So am not sure. Are these rev 7.1 in reality (even though they say rev 7 on them)?

So many questions to unravel the last years of C= engineering output on a shoestring budget and incompetent corporate management  

Any enlightenment appreciated.

All 9/03 MB's came with version 7 DB's.  The rev 5 must have been placed in the box along the way...  Rev 7's were standard on 9/03's.  FYI: 9/03 systems were manufactured in Hong Kong and in West Chester PA.  

The only differences are the West Chester builds had red writing for the serial number and white protective plastic for the mother and daughter board, while the HK units used clear plastic.  Otherwise they were pretty much identical...

Enjoy....

Thanks... I guess the West Chester builds were also NTSC/110v while the HK ones were mainly PAL/220v meant for the Euro/Asian markets?
