EPS Parts/Main Board Needed!
2003-03-13 by springpan
Howdy to all "groupies", Well, I'm here to bug y'all again about this problem EPS of mine. I've narrowed the problem to the main board for sure. This is a real drag because, as you all know, there are no parts available for this keyboard from Ensoniq. There's a MC68440P10 DMA controller chip (U28) that's getting hot and seems to be giving weird outputs and then there's U43- an Ensoniq proprietary (I think) chip that's not putting out the clock for the display board on pin 23. I know the display board is fine, though, because I can sub in a clock signal from elsewhere on the board and make the display board go into self-test mode and light up certain characters when pushing certain buttons. So, I guess I need a main board or those chips. What a drag. If anyone knows where I can get an EPS for parts or a main board, PLEASE let me know. There's a place in California called "Thesoniq" which can repair my main board if I send it to them, but they said it would be at least 100 bucks for this. They won't return my e-mails when I just ask for parts, however. So if anyone has a junker they want to sell, I'm interested. Hasta.
