Got a 1C in today for photos and additional testing. Works perfectly and is a hybrid of install instructions for the 1B and CD. You have to disable the chip like you do in the CD install, and then hook up the CE and OE to pads 10 and 12 where the original bios is. I'll get much better install instructions as soon as I'm closer to shipping these out.
I do have some dissapointing news for CDz guys wanting to do this mod. It does work perfectly on the CDz, but there just isnt enough clearance to close the case without cutting the plastic. So I dont think many CDz users will be willing to go that far. Or you can put the CDz MB in a toploader case and you'll have a lot more room to play with
One thing I do recommend, is removing the bottom metal shield from the CDz. Probably one of the big reasons why it is known to overheat. The shield is blocking any possible airflow from the three large-ish vents in the bottom of the system.
