The 8-bit Guy - My Dream Computer is Finally on Sale! (Commander X16 update)

  It’s interesting that Dave mentioned education as a possible market for these. I thought kids were learning Javascript on their school-issued Chromebooks these days. It would be nice to teach students about the concepts of computer hardware architecture… but the Commander’s architecture is kinda weird, being a hodgepodge of ancient (6502) and modern (FPGA), with bank-switched memory and the desire for backwards compatibility with Commodore peripherals hanging off of it like a lamprey. Sure, students could learn about computer architecture on it, but it’s hard to see how it’s better than other, cheaper options. Big money awaits if they can pull it off though.

    He’s got classic boomer brain about this: computers were good back in the day and now computers are just too powerful to do anything useful

      Or maybe there are people who find working in low powered environments that behave a certain way, more like computers did in the 80s enjoyable.

      It’s not about boomers or what’s powerful and what’s not. Some things are just for fun and that’s all the justification they need IMO.

  Though I really like the concept of building a new device which incorporates the inherent ease of programmability of the computers of yore, I think the 6502 is just too weird and limited for doing so. For example, in order to cram a halfway decent amount of memory into the thing they had to resort to bank switching. At the least they should’ve gone with a 65816 (apparently they tried but they initially had some problems with the '816 address bus multiplexing).

    Bro you can’t say that “the 6502 is too weird” without providing more context. Too weird for today’s standards maybe?

    Because the 6502 was everywhere back in the day.

    It’s like saying that sony walkmans are too weird.

      The 6502 was weird back in the day as well, just weird in an ubiquitous way. It’s registers are too small, it’s stack is too small, it’s address space is too small. Argument passing often had to be done using the zero page, and since none of its registers can hold its entire address space it requires hacks to implement such obscurities as C-style pointers. No current ABI can trace its origin to the 6502 (not even ARM).

      Sure, back in the day the alternatives at the price point were worse, but that doesn’t make the 6502 good.

      If you want a good CPU design with a 16-bit address space, take a look at the PDP-11.

    Yeah I see the Commander X16 as a bit of a folly, a hobby project by some serious retro computer nerds. I don’t think it has any viability as a platform, even as a gaming platform, as it’s a strange implementation of a weird architecture.

    That said, yeah there really isn’t something that is as imminently accessible as a C64 was, where the machine itself plugs into a monitor and keyboard, and you program the device using itself.

    Arduino requires a PC or other device to compile and run code, most of them are very low power devices that must have compiled binaries, so they’re programmed in C++.

    Maximite is another guy’s attempt to have a standalone BASIC machine. Uses fairly modern hardware but it’s still some guy’s project, and runs BASIC rather than anything remotely modern.

    Raspberry Pi and other Linux SBCs are surprisingly powerful, but also very complicated to run. You can do a college degree in Linux sysadmin.

    Meanwhile, I’ve played with the MicroPython language a bit, and as cool as it is, it can be a pain in the ass to manage because it runs on a microcontroller meant to be programmed from a PC, so there’s a pile (not a stack, not a heap, a pile) of software you have to manage. So it’s cool, but sorta supported on a bunch of platforms none of which are amazing to use and it’s got almost every problem that Arduino does.

      I had been thinking about doing something akin to the X16 but more modern, but realised that the main challenge with launching a product like this lies not in doing the design, but in coordinating all the people that are involved in producing the hardware, software and documentation (and hype, don’t forget hype). And you’ve gotta hand it to David Murray (the 8-bit guy): he’s knows how to do this, and has demonstrated this before with Planet X3.

    Also, how would that ‘weirdness’ impact using the device in a teaching context?

      People would learn bad habits.

      For example, due to parameter passing often being done via the zero page, recursion is unnecessarily hard on the 6502, whereas one could argue that recursion is one of the major skills to master for any programmer.

      They learn how to program in a more efficient way that makes better use of limited memory and CPU cycles. Which frankly is something modern programmers and game designers could very much benefit from considering how bloated and unoptimized much of modern software is, probably because they didn’t need to think about whether computers can actually run it.

    What would you like to see instead? Z80? Something else?

    source

    • irdc@derp.foo ⁨1⁩ ⁨year⁩ ago

      There’s plenty of choices. If you want that retro vibe go for a 68k, if you want something neat but obscure (and are willing to use an FPGA) choose the pdp-11, if you want to go with the flow then use risc-v.

      But please something that’s not actively fighting modern (that is, not 1970’s) programming techniques.

  I’m glad to see his project reach sale. Huzzah!

  For those curious how the X16 runs, there’s an emulator:

  Isn’t educational use the whole point of Raspberry Pi? It seems like that has way more opportunity for it with a modern architecture, ready-made robotics kits, and other maker-type applications that could get kids excited about electronics and programming.
