I did, however, notice what appears to be a hidden function to change the MIDI output channel. So far, I've determined that the LEDs are connected in a different order between the two board revisions, but nothing else in particular stands out. I'm in the process of reverse-engineering the two Miracle Piano firmware versions in order to see if there are any significant differences between the two hardware revisions other than the EPROM pinout. That would be very easy to repair: just one tap with the soldering iron - or as you don't have one - you could maybe even fix it by squeezing the solder back together with your fingernail (never tried that method, but it might temporarily fix the problem). If it's sometimes working, and sometimes not, then it might be a broken soldering point somewhere near those components (you might spot that when closely looking at the soldering points). The sound-engine schematic (see above link) is nicely showing where the right audio is routed through (J004 -> U10 -> U4D -> U3A -> U2A -> connectors).
If they are all having the same problem then it must be something between the connectors and the J004 sound chip.

Maybe the newer piano versions are doing that too (although the 8032 CPU is maybe a bit too slow to shift-out more than 8bits at reasonable speed, so SNES software may encounter lost bits when trying to the ID if there's one at all).ĮDIT: Is it possible to lift the black plastic that the LEDs are sticking in? Maybe that could help to get them well aligned.

Nintendo seems to have been quite strict that SNES controllers must send a controller ID code (in the 13th.16th bit of the serial data). I am wondering if there is a special BIOS version for the SNES. (I guess you won't be too motivated to desolder & dump the 32pin sound ROM?). (In case you have an EPROM burner or other tools for dumping ROMs/EPROMs). I hope there's some trick to get it back together!īefore you do - how are chances that you could dump the socketed 28pin BIOS ROM? I don't know if this thing will ever snap back into place. Maybe the real chip has some more text on it, allowing to identify it, or even to find a datasheet for it.Īnybody having one of those piano keyboards & could take photos of it's mainboard & chipet?Įdit again: DAMMIT, those LEDS just don't want to go through the holes. It is reportedly made by "Thomson SGS" (aka "SGS Thomson"), and the schematic is calling it "J004" (which looks more like an odd abbreviation than like a valid component name). And the sound generator, which may be harder. There seem to be two ASICs on the PCB that might be easy to guess how they work.

Would be interesting to know if the two ROMs are having sockets (would make it easier to dump them), and if they are stored on ROMs or EPROMs (or in worst case: if the BIOS is located on-chip in the CPU).Īnd, if there are different PCB version ore stickers on the ROMs (theoretically all pianos should be identical, no matter if it's a NES or PC keyboard, but considering the miracle's lifetime, there might be several revisions). Only a few important details are missing: The BIOS-ROM dump and SOUND-ROM dump, and details about the sound generator.Ī nice and simple thing to start with would be having a photo (or scan) of the piano's mainboard. Looks perfect for rev-engineering and emulation.

midi messages described in owner's manual Some things that are known are found here: In so far, the keyboard should be quite popular and not too rare. Have there ever been any attempts to rev-engineer to the Miracle Piano?Īside from NES/SNES versions it has been also sold for PC, Amiga, Macintosh, and Genesis - all versions using the same keyboard (and differing only by the included software and connection cable).
