Hi folks....
I have been slowing collecting parts to do a hardware mod to a LC 575 board so I could slide it into my Color Classic. I am not doing a video mod. I am keeping (for now any way) the 512 X 384 screen resolution. All I am trying to do now is install a faster board so my Color Classic can have a bit more speed. I am running a Color Classic II board in it now.
I have seen posts on this forum saying that if all I want to do is install 8.1, I can just slide a un modified LC 575 logic board into my CC, and install 8.1. I was skeptical. But I ordered a 8.1 CD anyway. This CD is a apple branded CD.
I installed the LC 575 board, and healed down the "C" key. I boot to the bomb (just as I did with a 8.0 CD). I received a error message to boot with extensions off (as I did with a 8.0 CD) and had the same problem. I think this will just not work. If someone knows otherwise and can toss me a bone, please post a message.
I am going to do the resister mod to the LC 575 board. This is taken from the Mystic upgrade page here:
http://colourclassicfaq.com/mobo/mystic.shtml
On the bottom of that page I read this:
*************************************
2.1.13 — I'm a complete klutz with ResEdit. Can't I do some soldering instead? Yep. Remove R116 (zero ohms, located on the bottom of the 575 logic board to the left of RP9) and solder a 4.7K ohm resistor at R109 (near R116). If you don't have the proper resistor, you can get away with using the zero-ohm resistor you just removed. Make sure nothing is installed across R110 (remove anything you find there) and you should be ready to go.
*****************************************
So I am thinking that is the way to go. I wanted to run several OSs on my Color Classic, but my stupid SCSI2CF adapter will only allow me to boot to one partition. So I am going with a "modern" OS and hope to install 8.1
Feedback welcome
Thanks
