6:36 - look ma, I made it in a LTT video! lol A few notes: - The alpha units were put together in a rush just so early game developers could have a chance to start working on their games for the Xbox's launch in 2001. The plan was to give devs a more polished dev kit, like the clear one seen at 6:36. Production was delayed, and they scrambled to get dev units into game developers' hands in the early days, hence the janky "off the shelf" nature of these early alpha 1 and 2 units. It wasn't originally supposed to be a PC, but they had to rush to put something together so launch titles could be made in time, despite production delays. - The entire case is basically a re-branded PC case. It's not custom-built for Xbox, including the front (other than the "powered by directx" jewel in the center). You could have walked into a store and bought a PC that looked almost identical to the Xbox alpha units in the early 2000's. I forget the make/model, but there are similar looking cases out there that are generic. - The BIOS doesn't load from the hard drive. Linus remarked at how fast it booted up "from a slow hard drive", but the BIOS is stored on the motherboard, similar to a PC's BIOS. The boot animation exists to give the system time to spin up the HDD and initialize other components. - The prototype units were not ever meant to go into production. The line about "Xbox needed something cheaper than an $18k block of aluminum" is partially correct. Yes, it would have been ridiculous to build the giant metal X consoles for developers, but that was never the goal. The big metal "X" prototype units were only meant to grab people's attention in the unveiling. The real reason why these alpha units were made was due to production delays in getting devs the more polished dev kits (which actually looked like Xboxes). Alpha units are extremely rare. I really hope LTT stores/archives these things well. There's so few left in the wild!

I believe the remark about booting from a slow hard disk was in regards to the operating system, not the BIOS. Linus was comparing boot times between normal Windows 2000 and this stripped down OS, which felt comparatively instant. I think Linus was only mentioning how cool the custom BIOS logo was and how it didn't feel like that was commonplace at the time for pc builds like this.

I recognize that case. It was a YCC-802 by Globalwin. We used to sell those like hotcakes for custom build computers. They were one of the first cases with beveled edges, complete thumb screw mounting for everything but the motherboard, a system built in for holding video cards in place, a removable/washable case fan filter, removable motherboard rack, and room for a whopping 7 hard drives. For a case from 2001 they were way ahead of their time.

[@VexAcer]

I grew up on the PS2 ver. as well so I can testify to how long it takes there. The final version on Xbox only takes about 10 seconds which makes sense. Usually OG Xbox had better load times in general because of the beefier CPU and ability for games to automatically cache data to the hard drive.

[@Taylor_King]

I had it on xbox and remember it taking ages too

[@b1llygo4t]

The unfortunate side effect of the ps2 being significantly weaker is cross platform games generally defaulted to the capabilities of the ps2. The grand theft auto series is a great example of how much more powerful the xbox was. Rockstar released all three games on xbox with upgraded graphics.

[@WJCTechyman]

Well, the drive read speeds were different. DVD read speed on PS2 was something like 2x while on Xbox or GameCube it was much higher. GameCube games seemed to have a pretty fast load time and part of it was the small capacity but I think Nintendo also tried to optimize the game discs so it didn't take forever to load. The Wii was respectable but as the Wii U hit, it was a good system in its own right but took forever to load, didn't matter the media. The OS was the same way. I owned my Wii U since launch and even though the load times were improved, it still took its sweeta** time. I have a 1 TB hard drive on the Wii U and the bottleneck there was quite possibly the USB2 ports.

[@Tenchigumi]

​@@b1llygo4t My favorite example for OG Xbox's superior tech was Ninja Gaiden 04/Black. That was a game you almost certainly couldn't run at 60fps on a PS2 at its intended resolution, and it could easily be mistaken as a early Xbox 360 game. Hell, its remake on the PS3 only looked marginally better (if at all; in some ways it actually looked worse). Honestly, the OG Xbox was so damn powerful that in retrospect, the 360 felt like a pretty modest improvement compared to the jump from the PS2 to the PS3, something that became more apparent as the PS3 matured.

Most of my favorite games of that era were from the PS2, but the Xbox has a particularly special place in my heart due to how unique it is.

[@no1DdC]

And like Linus said, this was not particularly high-end hardware for the time at all. It was low-end, in fact, but they got away with it, because the other consoles with their custom hardware were even less powerful in order to be cheap to make. These low-end PC components ended up being far costlier (because PCs were expensive in those days), explaining the high price of the original Xbox compared to the competition.

@@no1DdC The GPU was pretty good, it was based on the Geforce3 which released earlier the same year. Obviously it was more than powerful enough anyway, particularly when releasing after all the other consoles.

[@WJCTechyman]

@@no1DdC I think the GameCube kept a really respectable power equality to the Xbox, in fact, it used quite a bit less power coming in. PowerPC processors were pretty powerful compared to Intel's 86 line. Added to that was the incredibly high bandwidth memory used on GameCube made it do things that a system with, at the time, standard SD memory had GameCube doing circles around the PS2. Also, the GameCube model DOL-001, with the help of a $50-200 plug in adapter is now compatible with modern displays. I had both GameCube and Xbox consoles, and I played them both. GameCube had some pretty good games in its day and the Xbox had multimedia features and software I liked to play as well. I enjoyed playing Oddworld: Munsch's Odyssey, Jet Set Radio Future, Halo, Sega GT and others as well as having the advantage of playing music back as well as DVD video on my Xbox. My current Xbox is the One S console I bought at the end of the One's sales period and am looking to get a Series X when and if I see it being sold.

[@nickwallette6201]

The original Xbox really seemed like a "we have a hammer, and everything looks like a nail" thing. It wasn't particularly clever, quite obviously being designed by a group of engineers who really knew PCs and not much else. The other consoles may have been on-par (or even under) from a raw performance standpoint, but they were much more tightly integrated devices. Just look at the hulk of a box that the OG Xbox is. It was expensive because it was a grossly inefficient design, hacked together as a small form factor PC with slight customization, and very little room to scale as they sold more of them during its lifespan. I had a lot of contempt for that whole project at the start, seeing as how many times Microsoft thought they were smart enough to corner various markets, only to limp away and axe the project shortly thereafter when they learned that venturing too far out of the core competencies is, like, _really hard..._ I figured it would be yet another one of those -- a "rich kid thinks he can be a video game console company" kind of debacle. It was touch-and-go for a while, and I'm surprised it survived at all. But it did, and despite that they had no business being there, they ended up as a first-class console vendor ... eventually. Although, I still think Sony has always had a much more refined UX than any of the Xboxen. But, close enough is close enough I guess, and you can go a long way on a vibrant software library. Right, Nintendo?

[@kipters]

@@sundhaug92 And that's how it got hacked :D

[@yjk_ch]

I watched video about how OG Xbox got hacked, and apparently the original security design relied on the fact that if you execute code against the top of the memory it would triple fault and halt the CPU. So they literally executed code towards the end of address space to halt in case something goes wrong. But Intel processors back then could start from either near top or very bottom of the memory. The CPU would always start at high addresses, but when it reaches the end of the address space, it goes back to 0 and continues execution. So if you could somehow put executable code at lower memory, you gained arbitrary code execution by causing intentional boot failure. And I believe this did happen on Xbox 😂

A fun story on AMD and Intel: AMD and Intel x86 processors are doing the same thing and can be interchanged without issues - Usually. However, they do have some usually insignificant differences in their implementation. As I heard a long time ago, these slight differences caused one of the first (of many) security issues the Xbox had, breaking it wide open quickly for modders. The XBMC (Xbox Media Center) originated here, which changed its name some years back to Kodi :)

​@@tOSdude Yes, Intel had to license the rights to the socket 7, socket 5 and I think previous to that was the socket 3. IBM forced Intel to have other manufacturers to make sure there was no interruption in production, starting with the 8086 era. So, there was Cyrix, AMD, IDT that also made x86 CPUs.

[@modchmod777]

@dataabort It was in how Intel and AMD handled overflowing the memory boundry. So when you'd get to the end of the 32 bit address space they'd do different things. AMD would halt at the end, Intel would wrap around to the start. The issue was the the boot ROM was mapped to the end of the address space and the devs were relying on the AMD behaviour to stop the CPU from executing any more code in certain cases.

[@xmine08]

@dataabort They're trolling and not being good at that. In any case, you're right, x86/x64 processors start in 16-Bit (Real Mode), then switch into 32-Bit (Protected Mode, called because it can protect resources using a MMU which wasn't really possible in 16-Bit), and x64 can go on into 64-Bit (Long Mode). To make things more complicated, each mode has an "emulation" layer which allows you to downgrade a task (process, ...) into the lower mode, that's used when you run a 32-Bit app on a 64-Bit machine.

Back in those days, many CD writers were SCSI because they had better through put and didn't suffer from buffer under runs due to the ATA bus timing out. One of the places I worked at in the mid-1990s had a setup just like that for that purpose.

[@nickwallette6201]

What's this about the ATA bus timing out? AFAIR, using SCSI was really advantageous when the source and destination drives (a HDD and CD-R, e.g.) were on the same bus. ATA devices hang out on the bus for a while, whereas SCSI devices grab their data and go do their own thing offline. Beyond that, any advantage to using SCSI was more that it might just be a more performant chipset than whatever IDE bridge was on your motherboard. Ditto drivers. Ditto the hard drives where the source image was coming from. At any rate, originally, CD-R drives were SCSI for the same reason CD-ROM drives were: The older IDE specification didn't really support generic media, having been adapted from MFM drive controllers that were basically very large floppy drives. So, your options were either SCSI, or a proprietary interface like the 40-pin MKE or Mitsumi interface, or the 34-pin Sony interface, etc. But once ATAPI showed up to the party, things moved rather swiftly in that direction, with SCSI hanging around for the Mac / Amiga / UNIX workstation market, and the handful of PC enthusiasts that felt inclined to spend $300 on a controller card. (Guilty.)

[@Clavichordist]

@@nickwallette6201 Back in the old days, the ATA bus was much slower than SCSI. The devices themselves couldn't keep up with the data throughput required for continuous writes necessary to burn a CD-R. This may also have had to do with the amount of RAM, cache, and other things associated with the machines back then. The other issue back then was the quality of the hard drives. The ATA drives weren't necessarily the highest quality compared to the SCSI drives. The early drives used to use speed compensation tricks to allow for quick reads and writes on one part of the drive compared to the other. A good example of this was the really crappy Conner drives. (Does anyone remember those? ;-) ). During this time, even Western Digital and Seagate ATA drives were crap compared to the SCSI drives of the times. I witnessed many disk timeouts during a CD-R burn. At $15 each per CD-R it got pretty expensive when writing a disk in the mid-1990s.

Glad you mentioned about the sudden CPU change, although it would have been nice if you mentioned that the change was pretty much the core reason why the Xbox got hacked, and could never be patched out. AMD dealt with how memory works in such a way that any attempt to write past the end of memory would cause it to fault out, and eventually crash if it happened again. Intel however just went from end of memory and started writing at the beginning of memory.

I'll never forget my first experience of the original Xbox. Some game called 'Halo' which nobody ever heard of blew me away and I was hooked. I also got a game called Project Gotham Racing which I didn't play for ages, cos I thought it was some racing/batman kinda weird thing, but it also was amazing! Included with the console was a DVD called Pitch Black. Never heard of it, didn't play it for weeks, but when I did... wow! This console cost me I think about £400-450 from Currys, and damn it was worth every penny back then :)

You can upgrade the cpu and I guess ram too in the Xbox, butit involves soldering. That would be a nice follow up video, trying to upgrade the devkit.

You need a lot of skill its not like there are pins on the side, they are replaced with solderballs underneath, any tiny pressure can rupture the solderball and flood the whole chip with solder it aint as easy buddy, go watch some reballing then you know 🤦

[@SurgStriker]

A reason dev kits have so much more memory is because they use a LOT of proprietary in-house software alongside the games themselves. You can end up running a half dozen programs at once on top of the game for various purposes of monitoring and testing. Retail models obviously have most if not all of that stripped away so they don't need anywhere near as much RAM.

[@bigtalljosh]

[@garyhome7101]

This reminded me about building back in the early 2000's and having to shop for parts. There were a lot of small dev shops around where you could pick up various parts to assemble into a build, but what I remember most is that many of these small shops had a significant investment in memory modules and processors, and most of them kept them locked into a vault or safe! And when a new shipment of something arrived, there'd be a que out the door as people stood around waiting to buy 16, 32, or 64 MB memory! And they weren't cheap either! 20 years later and all of that is so much dinosaur dust.

[@xbinxpurp6118]

[@maxwang7937]

The original Xbox software was actually not Windows 2000, but a mixture of Windows NT 4.0 Embedded and early Windows NT 5.0 (NT 5.0 would later become Windows 2000) code. The Xbox kernel is basically an embedded minimal NT 5 beta kernel, the boot loader is likely a modified NT4 boot loader. And it runs DirectX 8. The next generation, Xbox 360 dev kit is also quite interesting. This time MS switched to PowerPC, and guess who makes the most PowerPC workstations back then? The very first dev kit is actually just an off the shelf PowerMac G5🤣. MS formatted the drive and installed xbox software on them. Therefore it is possible to recreate a Xbox 360 dev kit with PowerMac G5 (model A1047 PCI-X or PCI-X-2). After the work is done, these early dev kits got Mac OS X reinstalled and sold. I think the fact that they switched to PPC so quickly must have something to do with early Windows NT having a PPC version, and the dev work didn't stop internally, despite NT4 being the last Windows to officially support PPC.

[@maxwang7937]

And being an embedded NT kernel optimized for low memory is probably why it boots so fast. Also it doesn't load the win32 subsystem like most windows do, but the xbox subsystem, and only some win32 api were used for booting up and running directX. The recovery disc is based on regular Windows 2000 SP1 though.

[@XENON2028]

the xbox 360 devkits have a specific gpu too though right

[@themacintoshnerd]

You can also do this using a PowerMac G5. As they were used as dev kits for the 360 very early on. They require a specific model of the G5, a specific (Mac compatible because PPC Macs won’t see PC GPUs at all) graphics card, and I believe an Ethernet card as well since Microsoft used it as a kind of DRM.

[@xbinxpurp6118]

You actually can use a PC Card in there no problem just not for xenon os. Any r420 card can be flashed w a reduced x800xt rom flashed using graphiccelerator or atiflash. You also need a 160gb hdd or higher. 512 ram or more and an Intel Ethernet card. You can also kernel debug through FireWire. The models you speak of are the 2.0ghz A1047 model pci-x alpha 1 with Radeon 9800 pro or alpha 2 is a 970fx with different cpu housing and is pci-x2. Suprised nobody has made any home brew for either machine. The g5 has a lot of potential with sdk 1888. 1529 is out there than the other builds… also that AmR sound card isn’t worth building an alpha 1 the cases are too hard to come by the terminator ram card and the mobo is 700 dollars. The 1529 hdd image or iso has a blades dash and og Xbox emulator. I played Halo all the way through and have a compatibility list.

[@WJCTechyman]

RDRAM was probably used in Silicon Graphics machines as well as the first game system to have it was the Nintendo 64. Even in it you had to have a jumper pack as Nintendo did something unprecedented at the time by making the N64 RAM upgradable. As much as it was underappreciated, the Nintendo GameCube had some features the others at the time lacked. Digital video and audio, super fast 1TSRAM, PowerPC processing and some advanced particle effects on the custom ATi processor. The mod scene for the GameCube now seems to have brought it to the forefront of vintage gaming. I have my GameCube from December 2001 still and have upgraded it with a GCHD Mk.II, LaserBear BlueRetro Bluetooth adapter and plan to put a PicoBoot on it at some point as well.

[@SoapSoapCrayon]

FYI the point of extra RAM on a devkit is to load debugging tools, and to run builds without optimizations, so that you can get useful call stacks on a crash. Modern devkits allow you to toggle it off and on, or give you warnings when you exceed regular system memory, too! And if you think that waiting 10 minutes to copy a build to a dev kit was an early 2000s game dev experience... well... I guess it was. It can take up to 30 minutes to copy over a game to the switch dev kit these days. We definitely do get a lot of coffees lol.
