Circuit Overview:
     A DK600 with purely digital interface near as I can tell and 73 timbric programs and 55 patches...Sander...what DOES that mean? :-) In fact a Nate Holloway has been so kind as to provide Service Photos inside the DK700. I notice that the "E" interconnect is a smaller one which is expected because that one goes to the old front panel as I recall. Also there is only one EPROM socket IC6. Otherwise it all appears pretty much the same SAVE the addition of a board called "Micro". This board has the NEC cpu and another EPROM and SRAM so it's a sub-system that among other things I'm sure controls the sequencer that wasn't present on DK600.


Service Tips:
     Assume battery issues are still common. Sander says there are TWO in these! However I see now one is a Li cell on the 'micro' board so not a service issue in terms of potential leaks at least. Just refer to DK600 page for more tips.


Parts:
I have several scraps from Siel units and lots of the discrete parts. Check Sander's site for a guy who has made RAM cards for these also if you need that.
