    Coming soon from Andr0 on the xbox discord is this neat looking USB-C power supply. Future add-ons include always on separate rails etc...

    You could use 4 small well placed blobs of hot glue, one to each side of the silver aluminium heatsink to the edge, just barely to the pcb. You may find this suitably sufficient to hold it in place. Can always be peeled off as well at a later date if required. They do get hot, though I don’t believe any manufacturer ‘designs anything to run hot’ as such, more like its designed to a price point with functionality and a known lifespan. Generally, under electrical thermal dynamics and equations, a device will have an overall increased lifespan where lower temperatures are achieved within its specified thermal operating range. Hence for example, for a given programmable logic device IC, these are often available in C (consumer) I (industrial) or E (extended) at thermal ranges. Others inc passives will state life expectancy at various temp curves. So practically, yes it can be worthwhile if you wish to extend a components lifespan on the board. Others may shrug their shoulders and cant be arsed, which is fair enough, if it works it works. If it breaks, buy another board. Depends on your own approach.

    A CPLD can still appear and program fine within it's suite but still have damaged macro cells for any I/O pin of the unit itself. This can lead you down the inevitable garden path... For the £1-£2 ish cost, best to replace the CPLD.
  4. trencherfield
    That or the damage was already done beforehand in it's prior state of use. As I say, the power supplies are SMPS (pieces of junk) and fall well below today's standards. They weren't great even when brand new! A re-cap on those isn't going to remedy that. Primary PC problems and failures have historically centred around poor PSU's. Actually, a great project would be a newly designed opensource power supply board to replace them that slots right in, new PCB and more efficient components onboard. Nope, haven't got the time before you say it. Still working on Xecuter 3.

    Probably due to voltage instability across the board. People change the CPU caps, but bear in mind, all those caps all over the board are now 1/4 century old and will be probably out of spec without showing external signs. Even V1.6 clock caps, which used to not have a problem are now showing the same clock cap symptoms. Also, as difficult as it may be, the power supplies need the same attention and more.... probably near the end of their lifespan as switcher units and the outputs probably look very rough on a scope.

    You can swap any DVD drive from any original Xbox into another without problem. The DVD drives are not tied to each console. So you can swap the non modded Xbox DVD drive into your chipped Xbox without problem. It will read retail games fine. If that's what you are asking.

    Try it set at 'Master'. Try with all the 80pin IDE cables, with it set on Master.
  8. trencherfield
    Sounds like it could be an issue with your sata/ide adapter and/or IDE cable type. Which sata adapter are you using? Which 80pin IDE cable are you using? Things to try; Different IDE 80pin cable. Different sata adapter if not a Startech one (regarded as most suitable, besides Nemises one). Check setting on sata adapter for HDD - Master/Slave etc. Also, what settings are in place for the Cerbios ini file on your hard drive?

    It's just a variable resistor pot with blue glue on it to set the position from factory. They often look like that.

    Looks like there is a bridge to the via.

    No worries, unless you're a relic like me from the zx spectrum era and before, then all the byte terms and abbreviations can be confusing when you first encounter them.
  12. trencherfield
    As he's already told you, that's 64Mb which is the abbreviation of 64 Megabit, not Megabyte (MB). Xbox original ram per chip is 128mbit = 16MB x 4 chips = 64MB factory RAM. There are also 125,000 bytes in 1Mbit.
  13. trencherfield
    Latest sales thread for these... There's 3 red full kits left on special price @ £50 each plus post. They will work on any version original xbox from 1.0 through to 1.6 just like the original xecuter 3 does.

    https://www.ogxbox.com/forums/index.php?/topic/9260-substituting-original-xbox-dvd-drive-with-pc-dvd-drive/ Most IDE PC drives will work with a chipped Xbox so long as you find the correct points on the PCB. They will read CD’s and Backup dvd-r’s games and such, but not Xbox originals. Way back in the day I was one of the contributors to the tutorials on Xbox-Scene for the Sony 1612 dvd drive. I found all the elusive points including the Z point, so it worked well. Still have the guide on a detached HD somewhere. Might be on internet archive along with others under tutes for xbox-scene. As for writing the firmware to include originals all I’ll say is, good luck with that. Also, using a sata dvd drive is just serving as a further obstacle to overcome.

    Purple kit sold to Shadow, thanks. 3 red Kits left. These will work with the new 256mb RAM mod of course using the X3 BIOS as per that guide.

    Without any external tools or DVD's? If that includes usb softmod exploit as well, then you must install a modchip. Openxenium or any Xenium based modchip has limited format tools within the original XeniumOS. See disk tools section. It's not ideal though and has various format limitations. Xenium-OS V2.0 User Manual.pdf See disk tools section. Prometheus may have improved this, don't know, never used it. Stellar will have a better system. Never bought/used one. Can't comment further. The files to setup the hard drive have to come from somewhere. Whether you use an installer dvd disk, build it on a PC, usb installer/softmod or FTP them to the hard drive, there's no getting away from that. Often used is Xboxpartioner 1.3 for better hard drive formatting. If you have an already setup (unlocked) xbox hard drive of any size, then you can just use a duplicator to clone it quickly and install it into a chipped Xbox also. Lots of ways, but there are a few chips with apps that can format a drive yes. You still need to install all the dash files etc though. Your least amount of tools (without using the DVD drive) then would be, install a hard chip with an onboard OS. Format the hard drive. (May still need to be initialised in a PC if new YMMV). Then connect via LAN cable to PC and simply FTP your dash files over to the Xbox hard drive to get you setup. You can go from there. Some chips with OS and FTP; Xecuter 3 Openxenium or Original Xenium + variants SmartXX Stellar

    Already opensourced and available.

    Just noticed these still on the side, boxed ready to post each kit. *Clearance price* £50 each! .... 4 available only as above. Full kit with cables and front switch, everything you need to install in any version Xbox. Royal Mail at cost. 24hr Tracked - £3.50 48hr Tracked - £2.70
  19. trencherfield
    Yes it was a known issue, depending on the version of Xenium OS.

    As I said previously I'd get around to this project. It's about time it was available to all and spurred on by a friends request, well here it is. Xblast Lite jed file. Fixed the syntax error in the code, something and nothing, compiled, then erased my black Xblast Lite chip (that was locked) then reprogrammed with the new jed I made. Works perfectly. LCD tested too. This is for the Xilinx CPLD version with TSOP recovery etc. BOM and schematic in the repo. You'll have to do yourself a pcb or wait until I do that shortly, but at least you won't have to mess with ISE and linux etc now. Enjoy.

    The 'Backup' 256k flash, yes from what I can see. We use a similar AMD variant now instead for the R3dux and the code spoofs it's ID instead. The main Xecuter 3 AMD 2mb flash is easily available. While testing I disassemble working Xecuter 3 chips and read the flash chips etc. These ID's are used within Xecuters BIOS and flashbios etc.
  22. trencherfield
    Well after some more research it appears the Xecuter 3 'Backup' chip is actually Spi as I suspected. It was manufactured by EON and is a EN29F002 256k with a null pin 9, making it an 'N'. EN29F002N.PDF This corresponds with this here... Source: https://chromium.googlesource.com/chromiumos/third_party/flashrom/+/798d2adc9527f724bc5096a646cf99efdbb6b59e/flashchips.h#324 and also I found within redux code.... Mystery over on that front then. That's why it will return 0x 7F 7F within XGecu software being read in a tsop programmer. They are two continuation device ID @ 7F. So when you now select the above device within XGecu you will notice the 'Check ID' tick box will be greyed out because it knows this. Anyone looking for a genuine above backup flash chip I'll save you the trouble looking, nope, none that I could find. Wasn't prolific like AMD unfortunately. So now we know both chips on the Xecuter 3. Hope this helps anybody searching in future for answers.

    Thought I'd have a crack at the old legend yet again with a completely different build. This is the work of Khoa Hoang, so major props to him. @maximus64 OpenX3. This uses the original CPLD of the Xecuter 3, the Lattice LC4128V, along with the usual same Xecuter flash chips and passives etc. Currently, I've hacked this onto a redux pcb purely because its what I had on hand and didn't want to hack up the other second duff X3 purple I have after fixing the first one shown in the tutorial I made for that, as I didn't know if this would work. This actually may be an even easier fix for broken Xecuter 3 chips in due course, but I'll get to to that some time in the future, as that just complicates things here. So it's on this PCB due to a couple of trace mods only, so ignore the redux pcb, I'll get around to doing a new PCB in due course. I'm still finessing it but it's running sweet as of now, bit of meddling to do regarding that backup chip as usual. It does boot whatever is flashed on it, but being a pain over ID. Still can't get the ID of that Xecuter 'Backup' chip. If anyone can help with that it would be appreciated. It's not AM29F002BB (redux) nor AM29F002NB (n/c pin 9) either. It will read and program, but it's not the correct ID. It responds 0x 7F 7F, which means it's several steps in according to jtag standards as far as I can tell. May need Spi. Anyway, not much else to say, but it's another working Xecuter 3 chip and on the original CPLD. Config live and all that jazz all there and bank switching etc. Mentions... Maximus64 - Openx3 Psycho_Chewbacca (aka Benny T) - legend in his own right. Ryzee119 (code) Ernegien (Xbox7887) - did the x3 IO registers. Team Donkey - OpenX3 Schematic/pcb etc. ^Props to them lot and anyone else involved. Will have a look at doing the skins thing at some point if I sort the backup chip. https://github.com/Ernegien/x3cl-skins I could have done this a while ago I guess before redux, but getting more used to the Lattice software.

    Nice. Must of been cool to get your hands and work on such great piece of kit. Glad it all worked out sweet.
  25. trencherfield
    That was a great fix
