Hello all, I am new to this forum, and have been searching around for someone with more experience with Casio CZ-101 troubles. Have had this synth for quite a few years, and I love it so much! I finally got around to doing some updates, like a backlit LCD. Then I moved on to building a 64 patch memory card, which is mentioned in the article down this page: http://www.vintagesynth.com/forum/viewtopic.php?f=1&t=59847 I have it constructed, only using 1k ohm resistors in the place of the 390 ohms, just because I had them on hand. I have made sure it is all connected properly and there is continuity between the cartridge pins in the Casio and the card. Whenever the card is connected to the synth, and I power it up, there is just a row of boxes on the LCD top row, and many of the LED's are lit up, but no functions are available on the keyboard. If I turn it off and remove the cartridge, everything works fine again. I guess I'm just wondering if anyone here has experienced this with a CZ... as I noticed one person on another forum stating they had this problem before, but did not mention ram cartridges or any solutions. If anyone has more understanding here, would the current limiting of the higher value resistors cause the card to be unusable, or is there a deeper problem with the cartridge circuitry within the keyboard itself? Any help or suggestions would be greatly appreciated! Thank you, Pat(Spivkurl)
