New Post - Performa Hack

Author	Topic
Macintrash New Member Australia 68 Posts	Posted - 05 May 2003 : 20:53:19 I have decided to use the IICi's power supply instead of the AT PSU (the AT ones too risky). Does anyone know the pinouts for the IICi PSU? Alsoon the wiring harness of the performa, there are two small ribbon cables. 1 was connected to the power supply, and the other was not used. What does the ribbon cable (connected to the power supply) do? Can a mac moniter be connected to this machine without a video out card, and if possible, how? Why am I getting no chime through an external speaker I plugged in to the sound out? Cheers. Edited by - Macintrash on 05 May 2003 20:55:28

What about connecting a moniter to the ribbon cable which went to the internal screen? Yer, the speaker could be plugged into the mic port. Ill try Cheers

One thing i should've mentioned earlier is that a power supply from an LC630 will also work, as well as you don't want to power the monitor (which you don't, anyway) The wiring harness and stuff is exactly the same as the 6x00 series machines. -------------------------- Give your dreams a chance.™ - Apple in the mid '90s Warrior maclover5 68k Macintosh Liberation Army Number of 68ks Liberated: 7 Number of Contraband (PPC) Liberated from the Dumpster: 1

Ill try My power colour classic did that, even when it most deffinetly was not booting, all it means is power is going to some parts of the board. If you get a chime from the speaker then you can be fairly sure it is booting. There might be a way to get video out without using the video out board (incidentally I didn't see a response, are you interested?) the board has a couple of small chips on it along with the DB-15 connector, I'm at work just now so I can't check. I suspect you would have to use a PDS video card (rare) or make a custom PCB to get vide out otherwise. Have you been looking at the Power Colour classic sites? they have a complete diagram of the edge connector telling you exactly what each wire does. -------- LC 2, LC 3, Q605, Perf 638, Colour Classic (160 603e) 6100, 7200, PTP 225 (Quad 604), PM 9600, G4 Cube
