Quote from: jensma on April 27, 2016, 11:01:41 amHey there!Since I kinda disliked my Gimmick repro based off a FME-7 I made a pcb for it.This is kinda the "beta"-Version of it, but it works just fine (the silkscreen '56pF should actually be 10nF and you have to connect two pins of the prg rom, see this photo -> http://jensma.de/upload/files/9kooqcpuxjaRwRPbsJrR0.jpg )You have to transplant your FME-7 and the capacitor of your donor card. The eproms (I used two 27C020) can be soldered in without any rewiring. Since there was no space left for any more DIP packages (except the AY-3-8912) I had to use soic's for the 74LS74 and 74LS139.If anybody want a pcb or two - just drop me a pn. I live in germany and international shipping should be around $3.60, the price for one pcb is $3 PS: The pcb has the exact thickness of original famicom-pcbs and it fits perfectly into a sunsoft-shell. In addition to that it's ENIG-plated!

Using one would have cut down on board size and necessary components.
Quote from: xIceMan on May 04, 2016, 02:15:18 amIs there a schematic for the YMZ to use for gimmick?
