Spectranet emulation

edited September 2011 in Emulators


Note that the emulation is by no means finished yet (there's no actual TCP/IP emulation), but it's a start. If you don't know what the Spectranet is, which planet have you been living on?

    I don't know, never heard of Spectranet before - maybe you can tell me which planet I have been living on, Mr Kendall? :razz:

    I'm very happy to see this. Soon we'll have real and emulated hardware talking to each other. Thank for the video.

    The planet I live on likes new features appearing on Spectrum emulators, but its destiny definitely does not depend from something completely unheard of so far :razz:

    Strange cos SpectraNet has been one of the main topics of chat in the Hardware & Emulator forums over the past few months.
    It's about the only thing Winston posts about atm...

    Well, what can I say? You learn something new every day :D (Pulling my tongue off my cheek, I have been active in the Hardware forum quite a bit in the last few weeks, but must have overlooked this since I was more concentrated on other, different topics.)

    This is awesome news. Next to follow: game programmers using the system to their advantage :-)

    Wow! Really looking forward to seeing it implemented.

    Enough has been implemented now that the current head revision of the Spectranet branch in Fuse's svn can now use a TNFS filesystem :-) I've already loaded a few programs over the internet into an emulated Spectrum via the filesystem.

    Unfortunately all the networking stuff only compiles for *nix targets at the moment. The windows port needs some help from someone who has experience using windows threads...

    With vague apologies for the big image.

    In other news, there is also a (very hacky) Windows build around. It's not fully up to date and so is missing some of the functionality of the Unix version (so no IRC yet), but can load games via TNFS.

    hmm, that doesn't look too good does it... I was referring to the lack of text wrapping :)

    It's probably the most significant thing to happen in the world of speccy emulation for years, is this. Well done!

    Is the 27000 address hardcoded somehow in the spectranet?
    In other words, does it work on TC2048 in hires mode?

    Which 27000 address where?

    27000 address?

    EDIT: do you mean when running the installer? This is just where the firmware installer program is loaded into speccy ram, once it has run all the code lives on the spectranet's rom.

    The RANDOMIZE USR 27000 was in the youtube video from the first page of this thread. So, does it work on the Timex 2048?

    I don't know... does the timex 2048 basic rom use RANDOMIZE USR address to run machine code? :)

    I think there are a couple of reasons why the spectranet firmware doesn't work properly as-is with the timex basic but it's all open source so it should be relatively simple to fix any glitches.


    EDIT: in fact is the tc2040 rom is identical to the 48k rom?
    It works in fuse anyway as far as I can see. Whether the real hardware works together is another question, as far as I'm aware no-one has tested it.

    I don't know the answer to that question, but I'll quote what Andrew said on the TS2068 Yahoo group when people were talking about what to get after obtaining the twister board (adapter that lets them use Spectrum interfaces on the TS2068 ):
    [The] SpectraNet is also targeted at the Spectrum ROM, but only in the firmware, which can be reprogrammed.

    This is also worth mentioning:
    One of the cool things about SpectraNet is that you can point it at a TNFS server and have it autoload a program from that location, e.g. a BBS program.

    On the downside no-one has done an 80-column driver for the TS2068 for z88dk

    yet, but there is code in the Tech Manual that could be adapted.

    We know the current Spectranet software uses its own font, but it would be interesting to see a Timex version that finally takes advantage of the high resolution mode. :)

    edit: By "Timex 2048" you probably mean the TC2048. In that case the Spectranet should work without any problem. The TC2048 has a very high compatibility mode with the original 48K. There were only one or two games that I can remember that wouldn't work on it because of some port issue, but the TC2048 is simply a better 48K Spectrum, and the edge connector is compatible too.

    Yes. The installer might not work in hi-res mode, but who cares? Just install in lo-res mode!

    In the CVS of the z88dk there are some routines for the Timex hires mode:

    The 85x24 mode is available with +ts2068ansi
