Posted by: AlpineRaven on 2019-06-14 16:13:39I have both logicboards - Quadra 650 and 800.
The only difference visually I can see is that 800 board has connector for external LED and jumper to activate Q800, without it it'll become Quadra 650.
The other difference is that Q650 does not have that connector, I added it on it and it does what Q800 does.
Q800 has ROM slot which Q650 does not have.
Performance wise or anything - is there any other difference?
Cheers

Posted by: Trash80toHP_Mini on 2019-06-14 17:04:37Is there an access time differential for on board memory? Shouldn't be as they're both 33MHz Machines, but there was a question about Quadra vs. Centris 650 memory. Maybe check the overclocking page, I think it's back up somewhere. That might give clues as to any minor differences.
Posted by: AlpineRaven on 2019-06-14 18:26:58Spot the difference -
Sorry could not image it all on here and img link didnt work either - I need to find new photohost page as I refuse to pay Photobucket.

Posted by: johnklos on 2019-06-17 21:12:26There are no speed or component differences between Quadra 650 and Quadra 800 models. The Centris 650, though, ran at 25 MHz, and some came with LC040 FPU-less CPUs and without motherboard ethernet.
