I guess that depends on what you DID do,and which of the three versions of MK1 you have. Leaving C87, C88, D23 allowsthe Poly-800 memory to run off in internal 5V supply while the synth is turnedon, instead of the memory constantly using the Lithium cell whether the synthis on or off. Is D15 still in the circuit? Did it already have a CR2032? Didyou remove R1 and D1? Did this synth have the solder pads where the batterywould eventually go, or is it a really early version without these pads?

Subject: [korgpolyex] MKI BatteryMod question.
I just bought a second Poly 800 MKI and I'm in theprocess of doing all of the standard mods. I was about to do the battery mod soI looked up the instructions online to refresh my memory. After doing this, Irealized that I didn't do the mod correctly on my other Poly 800 though it isworking just fine. What I didn't do is remove C87, C88, D23 and cut the traces.Why do you have to remove these parts? I left them intact and the battery modworks fine?
