  1. If you can do hotair, remove the CPU, cut the ground line, maybe add a wire somehow to get that reset line out there if required and somehow solder back the CPU, you might have enabled the JTAG interface. Please share the Jtag config files if your in luck.
  2. I love the entusiasm. Go check Bunnie Huangs old blogpost about Jtag: http://www.xenatera.com/bunnie/proj/anatak/xboxmod.html come back to us when you enabled the jtag machine. (dont think you will, N64freak might make a breakoutboard someday to do it, but only because we are curious) basicly you have to read: https://en.wikipedia.org/wiki/JTAG And thus, yeah sure, with it enabled you can start, stop, read all parts on the bus. IF you have the right bitstream to send (commands) on the jtag bus. for the CPU it might be posible to figure out how to do so, but the MCPX is Nvidia/AMD s
  3. The 5th USB port from the MCPX, its no longer routed out from the mcpx on later revisions of the board. I cant find the pictures the new owner took for us to verify they truly go to (or the 2 datalines that is) to the mcpx. a leaked datasheet confirmed a 5th pair of datalines on the pinout. FOund 3 images fromthis thread from when the last 4 where lost. check em. first was the full shot, the behind (Jtag port in the red box) and 3th was the closeup of the battery. I dont seem to have the later 4 here. grabbed a backup disk for other backup purposes and went looking anyway. Jtag confirmed
  4. I think this is the only picture I have currently. it might be from the new owner but I dont see a battery, so it might have been a diferent revision then the one in said topic.
  5. Yeah those Wii2hdmi adaptes are awesome, cheap too also: Hoi en welkom nederlands is overal wel een beetje vertegenwoordigd. (back to english)
  6. Is it ok to just point you here? https://en.wikipedia.org/wiki/Atmel_AVR Basicly Arduino like hardware. but a PC from 1995 wont play the newest game right? so specs of a IC matter @ripdajacker did you look at the xboxdevwiki ? http://xboxdevwiki.net/Xbox_Input_Devices#Protocol Im not sure if it is complete or enough to recreate the USB device but the Xqemu emulator uses it for emulating a controllers for the emulator. the Xqemu USB Hid emulated source is here: https://github.com/xqemu/xqemu/blob/xbox/hw/xbox/xid.c maybe this helps. Im watching this thread
  7. arent 2 CY7C68013A-56 EZ-USB FX2LP USB Develope Board Module or somiliar be easier? 1 acting as a host, translating the packets to buttons and variables the other will reply as client on the xbox? this board is used as a usb debug and USB devices aswell. Im thinking of the following application note: http://www.cypress.com/documentation/application-notes/an63787-ez-usb-fx2lp-gpif-and-slave-fifo-configuration-examples (I got 2 of these to sniff USB and debug my laptop, but havent used them yet... so no real world experiance with em yet) Or, get a OG xbox controller IC and reroute all but
  8. I might have an idea what you wanna try, but I suggest you look at the chipset itself first Intel i820 Chipset Family Technical Documentation Some people had success with diferent motherboards but still the same chipset. basicly, if windows would see the same hardware (use the same drivers), it would work. CC820 I believe worked aswell. Based on these docs and maybe combining these with the schematics for other parts on the VC820, you might work out a schematic for a Xbox alpha motherboard. I leave any reasons for why you would wanna try this or why not to another forum thread. meanwhile
  9. Awesome LPC rebuild guide. might come in handy. I found this next picture using google and it might help someone who is good with soldering and destroyed some pins. I am not sure if this still works for the 1.6 or the accuracy, but sure looks helpfull to know someone did this digging/reverse engineering already. (its damm small, most ppl, dont bother) Whoever made this, Thank you and im more than happy to properly report your name (X-S source)
  10. Only recently ive been looking at this manufacturing proces part where they get the kernel on the motherboard. "our" Blake Clements @OGXbox Admin linked me at facebook to the following url: http://www.ogxbox.com/archive/xboxsecurity.html look at the Modchip part. It states that But I do not know if this is said based on the observation mentioned or based on internal Microsoft or flextronics manufacturing personal. Blake also said that: So, the LPC port was used for programming? A bed of nails (pogo pins) should and probably be used to connect the write enable p
  11. We all have those moments of realisation later on. some sad ones, and some are funny to think back of I got banned once from X-S for talking bout Piracy XD, I learned from that, and only asked technical questions from there on. Wish I got into programming back then.
  12. Now thats a Xbox with a internal PSU cool
  13. Lots of work indeed it looks like. Also, the green is cool sad the psu dint fit in the case. any other mods in that puppy ?
  14. here is a list of all (rare) MCPX ic I know off: MCP X-mode 2 MCP X2 (DVT3) MCPX X2 (found in DVT4 and Sega Chihiro) MCPX X3 MCPX X3P (not sure, but my latest notes state I found some info on this N64freak picture, repairing a Sega Chihiro (google this if you think "sega?") N64 Freak in this thread on Assemblergames has also did some amazing soldering things :https://assemblergames.com/threads/what-is-the-diference-between-the-mcpx-chips-big-images.41069/#post-952246 [EDIT} from N64freak I now understand the SMC might not need to be swapped, so yo
