Can you tell us what you had to tweak in OSSC? I was planning on using an OSSC as well, and I'd love to skip the "trial and error" phase. Also, I'm not very happy with my specific OSSC box. I'm not sure if it's a hardware problem, but I have noticed (with other sources) the left side of high-contrast images get a blurry edge on the left side, with the luminance getting darker to the right. I definitely do NOT see this problem on a VGA monitor. I'm hoping it's not a problem endemic to the OSSC overall.

Thank you for this in-detail tour and portfolio of this well designed 8-bit platform, Adrian. And please let us not be ashamed to honor your important role as one of the "fixer" guys for the Commander X16 mobsters community ... :P :) (meaning: based on your important design and usability feedback and your expertise with home computer electronics.) So thank you for the latter and the video!:) Now to my opinion to a sidenote, something unimportant: I think the Through Hole Technology approach gives this design a very appealing character. Watering this down to CHEAPNESS and SMD would be a sacrilege. But that is only my opinion. Of course this design has also to be available for a reasonable price ... so fighting reality with my opinion of "the art and love of old-scool'ness" isn't an option. Also having two (or more) designs is putting pressure onto the hardware designers and their lives (poor Kevin!). Well, its complicated, as this is (hopefully, hehehe) not the road to commercial success, but for old farts (with due respect) to show the younger generations how they could get reasonable (as in "reasoning") access to computer technology. I mean, we old farts where mostly confronted by accident back in the day with computers, some of us stayed ... learned, got in love and fell into that rabbit hole. The advantage for us (at that time ... maybe you can confirm that, Adrian?), which is pure coincidence of our birthdate, was that we as humans were still able to survey such systems in their ENTIREITY. In fact for the ECO-SYSTEM of the ATTINY "Systems-Processor" (Build tools, libraries, compiler, not even mentioning the production of the hardware, here) ... every little bit surrounding this MCU by a multi billion $ company (which gone through many hands, btw), it is too complex to print even an error free manual;) Also the optional approach, the expandability of a systems isn't a bad way to go. At least this will make me feel like back then ... dreaming about my own 1541, or amber monitor, without jealousy towards my class-mate ... Hehehe:) Thank you again for showing this off, Adrian. And the whole design folks and community around David who helped to birth this dream. Von Neumann, Zuse, Nixdorf, Ada and Chuck Peddle would be proud of you all!;)

It's very interesting that through-hole off-the-shelf parts which started out as a sweet spot for DIY is continuously shifting towards luxury pricing. Cars we call vintage today were once just old and cheaper than a new car. Once they get old enough they become rare and coveted. This appears to be also true for through-hole 80s-style computers.

I got the mustang I never got as a teen but still looking for the Amigas that were lost to time/one of my mothers cleaning sprees. I kick myself for not buying them when they were cheap on ebay before the batteries killed so many. The electronics world is changing. In my line of work station owners expect microprocessor/fpga based new stuff to be repairable like the 80s audio gear my predecessors fixed. I can do some SMD work but most of it is not even a modestly equipped engineer can fix it anymore because it's all custom baked in house stuff that can't be off the shelf replaced anymore.

Of course components like FPGAs and large surface mount packages and super tiny surface mounted components would be preinstalled but all the through hole components I would solder in myself. I love doing that kind stuff. I remember years ago my dad bought me a DIY transistor radio kit from RadioShack made by RadioShack. It was lots of fun and it worked.

45:18 - "Again, Ignore the darkness." - me to myself every morning.

I've been following this project from its inception. It's a noble effort but so many of their current problems were easy to foresee. When embarking on a project like this you have to decide what business you want to be in. Designing the system, writing the software, shipping the Gerber file off to Asia and getting back blank boards are all very doable and fun. But manufacturing? That's another thing all together. They have been populating these boards by hand and have been having great difficulty manufacturing even the 100 boards they need to get out to developers. When I saw they bought a wave soldering machine to speed this up I knew they were in trouble (they're warping the boards). They thought they could get thousands of Yamaha sound chips but they were lied to and now they have to source them individually at 10 times their original price. Many of those individually sourced Yamaha chips have turned out to be fakes. There's a reason that most electronics are built in Asia. Their economy (and labor costs) are very different than in the west. Also, when big companies release a computer they contract with vendors for millions of units which gives them very good prices. There are many decisions I feel they made that were well thought out. The ATX power connector, the Nintendo controller ports, etc. But the bad decisions were the difficult to obtain chips (Yamaha) but mostly the decision to incorporate the Vera plug in module which is very versatile but FPGA based board which defeats the purpose of an 80's retro machine. Why not make the whole thing based on a better FPGA (like the Mister). A project in development overseas is the R800, an FPGA based Atari 800 from a company called Revive Machines which right now is vaporware. But if it becomes real, I'm very interested. Depends how expensive it ends up being. I hope that the X16 is a success but the odds are against them. They have a scaled down version in development without expansion slots and they may have a big company that has expressed interest in manufacturing it. They call it the game system. They haven't said who that big company is. Just FYI, the current big version of the X16 is at least $500 and is referred to as the development system. I don't mean to be negative about this as it is obviously a labor of love but the days of a couple guys designing a computer system in their garage are long gone. Apple did it almost 50 years ago but even back then they needed an Angel Investor (Mike Markkula) to invest a small fortune to make it happen ($250,000 line of credit and about $90,000 of his own money, more than a million dollars in today's money). He also negotiated a 26% ownership of Apple. Mike is a billionaire today. Sorry this post is so long.

Only difference between them and apple is that the X16 isn't meant to beat any sort of competition or revolutionize anything. It's just a fun community project made by people interested in the hobby. While David is a bit over his head...which, well, we all kind of know that about him at this point, he is still capable of getting stuff done, as are the people he's working with. Given that they've even gotten this far is a good sign. Also, while I get people are frustrated by the FPGA for video, it seems like people are beating a dead horse at this point. Even they didn't want it to be an FPGA. And since you mentioned the MiSter, for all we know someone will release a core for it down the line. The system already has a complete emulator available.

Dip logic is a major selling point of this machine: if you want to shove the whole thing into an FPGA, then you could just use the emulator and be done with it; the vera board is analogous to a custom video chip in the olden days.

Not a remotely reasonable comparison.

The Video Display Processor (VDP) used on the MSX 2 and MSX 2+ are actually off-the-shelf parts, descendants of the original TMS9918: The Yamaha V9938 and V9958.

E.g. pixel addresses in a framebuffer can be trivially calculated on X16 and don't have to be in a weird pseudo-tile mode like C64.

Geez guys... Look. Connectors cost money. That's just a universal truism. When you _actually build things_ (and don't just criticize other people's projects), you start to realize that a surprisingly large chunk of your product cost is "stuff" that isn't what you would think is the most vital. Connectors are definitely one of those things. Even pin headers aren't cheap. Especially if you need both male and female connectors. At least in this case, the sockets cost a bit of money, but making cards is basically free -- it's just edge connectors designed into the PCB. That, IMO, is a solid compromise. Edge connectors are probably also more robust than pin headers. It's a tried-and-true design. And yeah, it's not electrically benign with every card you can make fit into the slot. _Oh... well..._ Most things aren't. This isn't meant for mindless toddlers to go shoving retro carts into. It sidesteps what will most likely be the most common error, and that's already more generous than many bus connectors. Keying the connector would be great, but if you think you're paying too much for a commodity connector already, just wait until you see how much it costs to have the manufacturer create custom versions for you ... at least in the small production runs this thing will see. In summary... it's a DEV BOARD, for enthusiasts, to prove a design and test the waters to see whether it makes sense to continue cost-optimizing the design. I would say most of their choices were pretty reasonable in that regard. I question the use of the Yamaha chip here, but otherwise, it seems fairly well thought-out. Better than most people would do in their situation, at least.

If they were going to use FPGAs anyway, they should have just made the whole design FPGA-based. It's also a nightmare to assemble, and is far from affordable. It was *very* poorly thought out.

Hey Adrian, fan of your channels (been subbed to your two main ones from my personal account for years). One minor semi-correction on the topic of sound... The YM2151 was typically paired with 16 or 32-bit systems - it's most often found in systems powered by a 68000 (Sega system16, x and y boards, Capcom CPS1, various Irem boards, the sharp x68000 and MANY more). Usually the CPUs in those systems run between 7 and 12 mhz. However... these systems also often include a z80 that runs between 3.5 and 4 mhz to specifically manage the sound. In some cases though, that second "sound" CPU doesn't actually do much of anything. I've been following the x16 from the very start. I think it's an interesting concept and enjoy seeing the videos on it and what it can do, but honestly it seems pretty impractical, especially from a cost standpoint. I know the goal has always been to reduce cost over time and shrink it down and I'd really be interested in it if it ever hits a price point of somewhere around $100. But I know we're a long way away from that. Anyway, thanks for all of the detailed videos on the x16, c64, apple II, amiga and everything else!

Not really that far from $100. There are FPGAs that have enough LUTs for the entire system. The VERA or the YM2151 ones are not the big. They are big enough to do the job. The reason the DIP one is getting the attention it is, has to do w/ the demand. A lot of folks said "$300-500 and it will have socketed DIPs. When can I get one?" Is that everyone? Nope.

Hardware limits are what gave those old retro computers their unique "personalities". The varied ways that different manufacturers used to make the best of limited RAM, clock speed and functionality made each system a treasure trove for programmers to explore and take advantage of, unlike modern systems that all have the same capabilities and therefore all seem the same with no individual personalities. I look forward to a future version of the Commander X16 that heavily utilizes FPGA to vastly simplify and cost-reduce the overall design (and future-proof the motherboard because it would not rely on being able to source parts that are not made anymore). It would also mean that tweaks could be made to the functionality of the system.

As someone who has been eagerly following news about the Commander X16, a retro-inspired computer, I have witnessed the great interest it has generated among retro computing enthusiasts. However, recent cost discussions on the 8-Bit Guy's channel have given me pause, making me realize that owning one might be beyond my reach. This realization has led me to reflect on the niche market for the X16. While it offers authenticity, learning opportunities, and a vibrant community, its price point may restrict ownership to a passionate subset of retro computing enthusiasts. Considering alternatives like emulation on existing hardware might be a more accessible and cost-effective way to experience 8-bit computing.

Not really, as he mentions it runs a fixed 640x480 resolution which means each character would need to take approximately 4.85x11.2 pixels in that "grid" - and it would have to implement this by integer scaling scaling the fixed 8x16 pixel font. I suspect calling the result "unreadable" would be charitable! All the text-modes are oriented around this - basically toggling borders, double width and double height as needed, except the 80x60 which appears to run with all off and a 8x8 pixel font - I guess it's possible it's always an 8x8 font and even 80x30 is scaled but it doesn't look as rough as that should look. As he mention later this does mean the sides tends to get cut off in high-res mode on CRTs if the program doesn't use borders. I suspect that if anything could make them change how it works that would be it, but they seem fairly set into this, I don't see a fixed crystal so it MAY be a "small matter of programming the FPGA". But FPGA programming isn't easy.

The C64 _does_ have those signals. • `R/W̅` is on pin 5 of the cartridge slot, which solves your "writable RAM" problem. _Anything_ in the cart can tell if the computer's trying to read or write it, and respond appropriately. • There are two specific address ranges, $DE00 and $DF00, with their own decode pins on the cartridge port, `I̅O̅1` and `I̅O̅2`. So that makes it dead easy to have something interpreting commands there. But that's just for ease of use and as a convention; the cartridge port sees _all_ writes the CPU does (except for addresses $00 and $01), so you can pretty much use any address you like to receive commands. • There are various modes for what the cart can take over (i.e., be guaranteed that internal devices will avoid responding to), but the broadest one is by asserting the `G̅A̅M̅E̅ ` line which maps 4K of C64 internal RAM to the bottom 4K of memory, and leaves _everything_ else to the cart.

@@Flashy7 I see two fairly large benefits to the REU way of doing things: 1. You can transfer arbitrary-sized units of memory from 1 to 64 KB, rather than being stuck with fixed page boundaries. So if you wanted to, say, transfer just one frame buffer worth of data (as is done by the "Globe" demo), you don't need to swap out a bunch of other data. This is particularly important when working near small areas of important stuff. For example, if your page size is 8 KB and you want to use different memory anywhere under address $2000, a bank switching system would also be switching out your zero page and stack which is almost invariably not what you'd want. 2. The REU leaves all existing address mapping working as it did before, so programs that depend on it need minimal modification, and programs unaware of it have a minimal chance of being broken by it, even if other things in memory (e.g. a TSR program) are simultaneously using it.
