  1. If you're thinking you've heard the "Homer" talk before, you're right. This thread is eating its own tail.

     

    Kevtris brought it up first, here

     

    PlaysWithWolves embellished the concept, here

    Just go read the whole thing, it's too good to summarize.

    Ha!, now I remember reading the post from kevtris. I missed PlayWithWolves' post though.

    The Chameleon clearly needs its own subforum so we can categorize things in topics :P

     

    The only one who can add something new to this thread is 'Mr Lee'.

  2. Let's remember that Nintendo's games, *generally* but not specifically, are aimed at children and teens. I'll make an assumption that most of us in this thread are older with cars, bills and years of gaming experience... but from my 11 year old stepson's point of view, the Wii U has been (and still is) an incredible console that's provided hours upon hours of entertainment.

    True, the Nintendo WiiU (and the upcomming NX) is the only console I would consider for my kids (7 and 4 years old) since they aren't into gore and blood.

     

    It is also the only console they are interested to play in the stores/shops.

  3. The only difference between a software emulation and a hardware emulation are levels of abstraction. How do you class, for example, a processor that uses microcode to implement its instruction set? How is implementing a state machine in HDL any different from one implemented in software on a processor? There is absolutely nothing inherently more accurate (or more "pure") with hardware (FPGA) emulation as opposed to software.

    Could software emulation work/interface in realtime with a cartridge?
  4. Someone asked me this question about this device:

     

    Surely this is just emulation, correct? What will this do that you can't do with an android box or a Raspberry Pi?

     

    I'm not sure how to answer this. I think it is quite a bit better than just emulation, but how should I answer this? Please advise. I think this is a very nice device that's in development, and I want to have good answers to these questions! :)

    I would say:

     

    FPGA: Replication of the original hardware on an electrical level. The electrical signals in the FPGA can be the same as the emulated system, therefore the replicated hardware can be made to act 100% like the original hardware.

     

    Android box or Raspberry Pi: A microprocessor with a program (the emulator) that is working very hard to emulate all the parts of the original hardware. Like a juggler who holds many balls in the air.

     

    Besides that, the FPGA of kevtris has a configurable clock so even that element acts like the one in the original hardware (possibly eliminating audio and video timing issues). Something impossible on other hardware (Android etc.). Even the HDMI upscaler is directly tied to the emulated system so latency is brought to a minimum.

  5. My biggest complaint with this clone is that it lacks joystick ports that later Speccys had, and the keyboard is something Sinclair would have done to save money.

    I'm not even sure it has an AY sound chip. Since it's probably FPGA based, you might be able to add the sound chip if it's not there. But you'd need an external joystick interface.

    It seems they have changed the specs then, since the AY and DB-9 ports are mentioned now?:

    The Spectrum Next is fully implemented with FPGA technology, ensuring it can be upgraded and enhanced while remaining truly compatible with the original hardware by using special memory chips and clever design. Heres what under the hood of the machine:

     

    Processor: Z80 3.5Mhz and 7Mhz modes

    Memory: 512Kb RAM

    Video: ULAplus featuring expanded video modes and colours

    Video Output: RGB, VGA, mini HDMI

    Storage: SD Card slot, with DivMMC-compatible protocol

    Audio: AY-3-8912 or FM2149 audio chips (selectable) with stereo output

    Joystick: DB9 compatible with Cursor and Interface 2 protocols (selectable)

    PS/2 port: Mouse with Kempston mode emulation or an external keyboard

    Extras: Multiface functionality for memory access, savegames, cheats etc.

    Tape support: Mic and Ear ports for tape loading and saving

    Expansion: Original external bus expansion port and accelerator expansion port

    Accelerator board: GPU / 1Ghz CPU / 512Mb RAM

    I'm worried a bit since this project lacks the impact of the Vega, the Vega was just there. I hope this isn't going the same way as that other promises based machine...
