Schematics for the SF-7000 and SC-3000 Service Manual
Posted: Thu Mar 22, 2007 12:59 pm

I have just received a package containing...
* SC3000 10-page flyer. Some interesting reading * SC3000 complete schematics (1x A3) * SF7000 incomplete schematics (2xA2, 1xA3). I am missing the left hand side of the first page, which is the CPU part, apparently. Does anybody have this missing page? |

Good that you won that auction. I was on it at some point.
Try to have some scanned if you have the time :-) (I don't have the "missing page".) |

Argh, I had just been desoldering stuff off my SC-3000H board to trace out some of the connections. ;) Are these official Sega schematics, or 3rd-party schematics that somebody reverse-engineered for the purposes of repair? |

They look like original Sega (need to have a closer look at the documentation in the corner)...well, old photocopies of the original for the SF7000 and the SC3000 looks very professional and is not a copy. |

Happy new year :)
Marc posted some stuff last year: https://sites.google.com/site/mavati56/sega_sf7000/sc-3000-sf-7000_docsandschema... SC-3000_Doc_Develop_Graphisme_Fr.pdf (7494k) Marc Le Douarain, 6 déc. 2014 à 05:20 v.1 SF-7000_schematic.pdf (1517k) Marc Le Douarain, 6 déc. 2014 à 05:23 v.1 Sega_SC-3000_ServiceManual.pdf (17114k) Marc Le Douarain, 6 déc. 2014 à 05:23 v.1 Those should be added to http://www.smspower.org/Development/ServiceManuals-Index and http://www.smspower.org/Development/SF-7000 ? (not sure where the schematic would fit), if somebody feels like adding them :) |

There's also a list of cartridge and tapes available in France that he gathered:

These are great!
Looking at the different variants in the service manual; RGB model: France NTSC model: Japan (JIS apparently stood for "Japanese Industrial Standard) PAL models; G-PAL: Used in most of mainland Europe, specifically Italy and Finland as far as SC-3000 is concerned. B-PAL (Australia) B-PAL (New Zealand) Those two are self explanatory, but it's the following models which are interesting; I-PAL: Used in UK, Ireland, Hong Kong, and South Africa. UK, and Ireland can be ruled out. Wikipedia's SG-1000 page (which SC-3000 shares) used to say that it got released in South Africa, but with no source. Additionally, here's a generic PAL variant (no Yeno sticker) of Star Jacker from a Hong Kong based seller, which previously made me wonder if SC-3000 or SG-1000 might have been released there. B-PAL (Southeast Asia): Used in Singapore, Malaysia, Thailand, Indonesia. I guess that Singapore would be the most likely place for this model to have been released. It's the first that I've ever heard of SC-3000 getting released in this region. Maybe there's an ultra-rare PAL Mahjong variant from Hong Kong/Singapore waiting to be discovered :p |

Wow, really cool to have the detailed information about both custom parts in the SC-3000. I'm surprised they explained how it worked this completely. | |

Very cool! I had been thinking to my self lately that I would really like to pull a part an SG-1000 and make a schematic. Now I don't have to! :) | |

New SF-7000 Schematics obtained in 2022

Below are the SF-7000 documents I recently obtained.
Previous one had "1 of 3" (A3) only. We now have "1 of 3" (A3), "2 of 3" (A3), and 電源部回路図 ~Power supply circuit diagram (A4). It's unclear if the power supply diagram is meant to be 3 of 3 or if we are missing that. I obtained 2 copies of each, one is bolder but not necessary more readable. I scanned both just in case, labelled "Version A" and "Version B". Could someone assemble them into a nice PDF (by combining both sides of each, etc.) ? |

Alternate SC-3000 Schematics document

I've also obtained a slight variant of the SC-3000 schematics. It seems more or less the same but with a Sega document templates, and some handwriting changes. I've scanned two version. Attached.
Could someone combine both sides into one? |
