| 475/605 motherboard in 550 |
Posted by: Geforce2187 on 2017-04-22 19:02:36
The 475 and 605 can be upgraded to a 68040 33 MHz (or possibly the 40 MHz???)
Is it possible to install the 475 or 605 motherboard in the 550 all-in-one?

says it's possible, but online I don't see any slot connector on the 475/605 motherboard that the 550 has

without the edge connector no. I believe that is incorrect. The 550 uses the same motherboard as the color classic II.

I suspect somewhere along the way someone has mixed up that the 575 and 475/605 boards (which are meant to be pretty much the same logically) are compatible physically, and they're not.
It'd be worth dropping a message to lowendmac and letting them know that's wrong.

The 550 can't take the 580 or 630 board because they use IDE instead of SCSI, correct? Or do those boards support SCSI as well as IDE?

they cannot take it. They do support scsi still externally but not internally. I am not sure if you could just put an ide drive in place of the scsi drive and change the board as I have not tried but i dont think the cables are the same.

Is there any difference between the 550 and 575 models besides the motherboard?

575 will work but video mod or system will need to be modified to work in a cc.

Is there any difference between the 550 and 575 models besides the motherboard? The 550 uses a caddy cdrom drive.
