Quote from: obcd on September 21, 2016, 12:05:07 pmI already was afraid of this.You likely have a problem with your unit io card. Basically, that card combines a number of things.1. The boot flash drive. (Which you have disabled at the moment)2. The nvram which is memory mapped in segment C800 (If I remember correctly) (For the highscores)3. A soundcard with buildin amplifier4. An interface to the security dongle.5. An interface to the coin acceptor and the test and service button. (Should be able to drive a mechanical counter as well)6. An interface to the 16 dipswitches on the board7. An interface to additional in and outputs that can be used to connect buttons (currently unused)8. A serial interface that can be used to connect a pcIf you have a problem on your io board, it can affect one or more than one of it's functions.In your case, the boot flash drive is failing, and probably the interface to the security dongle as well.It wouldn't suprise me that none of the other functions are working either. I have one lying in front of me with similar symptoms.A common problem are the pcb finger contacts or the riser card finger contacts. You cleaned those already, so you are facing other issues.I have a couple of test programs to read and write the nvram. They can be used to test it's functionallity.You could try to find a second hand io board on Ebay if you are willing to go on with the unit.If you are not, I am interested in buying the security dongle and it's small interface pcb (the board that connects to the 5 pin on the io board). OK thank you. Unfortunately nobody on eBay is selling an i/o board. Just the motherboard which I don't need Should I just suck it up and buy something like this? Seems ridiculously expensive: http://www.ebay.com/itm/Megatouch-XL-to-Maxx-Ruby-2-Upgrade-Update-Kit-5000-6000-Gold-Platinum-etc-/361121547775?hash=item54148585ff:m:m2_55DvZeZXmuziQoTOz4xw

Im not sure if this was ever answered for a Megatouch Gold as I am trying to bypass the invalid key error with a bootable hard drive. Any help would be appreciated. Thanks
