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...

IMHO, the West Chester Builds failed less and seemed to take a bit more abuse, at least this is in my case.  The 3k is a great box, but they can be very troublesome if they weren't taken great care of.  Unfortunately, 3k's tend to be more twitchy then the 2000 and 4000, and fail easier.  

I still love them, funny that they are the most expensive desktop to purchase, when they are so picky and require the most work.  At least they did have a high build quality with good stuff in them.
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?

No most 110 units I come across are from Hong Kong.  1 in 5 110 3000D's I come across are from PA.

Don't know about the European powered ones.  The 3000's were both NTSC and PAL via a jumper.
