The MK3 is probably bad, which is what Brian will tell you... Officially there is no way to fix it... - thats because no one wants to open the unit and make Flash chips that hold the corrupt OS clear - because needless to say those traces are small. But in reality/theory if you manage to open the unit, remove the CD-ROM drive, there is a chrome cover under it - remove that one. Now you see the CPU, RAM and the flash Hard Drive of the MKIII computer . The question remain, how do you erase the hard drive - well the theory presents itself: If i remember correctly, there are 2 chips made by Fujitsu connected in series named MBM29LV650UE or MBM29LV651UE. Note that there is a colored dot in the corner of each chip - it marks PIN1. According to manufacture's spec PIN37 is Device Power Supply (the +), PIN27 and PIN46 are grounds I think only one needs to be connected to the power source but you can try both as well if I'm wrong. So now that you know that info, you need to connect a 3V DC power source (aka a 3V battery in my theory should work) NOW here comes the main part PIN12 is marked as RESET pin in the manufactures spec... - Connect it to the same wire as you have pin 37 connected to. If you do it to both ships in theory it should clear the OS and then It should give you the ability to boot from the CD to load the OS.

I'm not a 100% sure that will reset the chips - but what do you think Brian, does my case hold water?
