VTX 5000 Anything I can dial into?

edited May 2014 in Hardware
Is there anything currently available that I can dial into with a VTX 5000 modem?

Any BBS, etc.

With or without one of the tapes available to make it do comms.

Anyone have any ideas?

    I did have one, but I EBayed it about 5 years ago, only sold for a few pounds but I thought it'd be better in the hands of someone that would appreciate and/or use it.

    Space is at a premium so I like my collection to be a practical one, stuff that sits on a shelf and doesn't do anything is better off in someone else's collection although It'd be interesting to see if there's still anywhere that you can dial into with one of these.

    I have one, somewhere.
    Wasn't there someone on css who had hundreds of them?

    Yes, Brian Gaff but he's blind.

    I have the Beckman 5000, the version approved by the Swedish telecom monopoly of the time to be connected to the phone network (and with the huge native phone connector). Unfortunately the ribbon cable was misplaced many years ago when I moved. Without it can't even check if it is still working.

    I also have a Prism VTX5000 here, never used it.
    Don't know if it is still operational.

    Seems a bit out of time to me.

    I have the Prism for the Spectrum, the TS2050 Westridge modem for the Timex Sinclair 2068 and the Byteback modem for the Timex Sinclair TS1000. Someone once told me there's no way to connect to anything anymore because even the slowest dial-up service is too much for them. If there's a way to be a host for any of these old modems to connect to, or a way to establish a connection between two users who have the same modem, I'm not aware of it.

    I was never part of the world of BBSs. I imagine it was fun to have people connecting to your own BBS.

    I thought they're fixed 330 up, 1200 down or something aren't they? so you couldn't even get someone else with another modem to dial you up.

    Unless you can change the speed to be symmetrical with jumpers or something.

    you could probably set up a pc to act as a gateway, but then why not just use a null modem cable... or a spectranet :)

    But to get these old modems working again would be great too.

    I own a TS2050 modem in silver box and a TS2050 modem on a custom box.
    Never fired them on.

    No comments about the video... (That's because no one's interested. - Ed.)

    Well, here's something that might be interesting to someone.

    The VTX 5000 certainly runs at 1200/75 baud and possibly at 300/300 baud (I haven't verified the 300/300) and yes, with a comms package tape you could talk to other spectrum users but I don't know if you can use the same comms tape to call anything other than a spectrum.

    Are there any BBS's still around?

    Its a shame these can't be used for anything, even just the odd bit of fun tinkering around.

    1200 down and 75 (yes, seventy five, you can actually type faster) up. However, that's not just the only mode, there is also a 1200/1200 half duplex mode (that's what the TX/RX switch is for) for Spectrum-to-Spectrum communications. There were even a few bulletin boards that run in half duplex mode (I'm not sure how, perhaps there was also a software mode to change from TX to RX, or maybe my memory is just faulty).

    Any bulletin board still around would in practise need to support "reverse viewdata mode" (i.e. 75/1200) and these things were rare back in the day. There exists the possibility that The Gnome At Home is still up, apparently the guy who ran it back in the day has kept one node in continuous operation, and this had the reverse viewdata mode. The phone number was (01) 888 8894, who knows what it is now!

    I've been pointed at this thread....

    I've rebooted the relevant boxes, as 25 year old kit tends to crash a bit, and nobody had noticed... There's one line working (I'll see if I can get another up though) available to my old Viewdata BBS, "Ringworld" ... it was mostly used for me testing software and page designs, but it did used to be publically available.

    The number is 03333403311 - (that's a "Uk-wide" number that would be free if you have an inclusive calls package on your phone.)

    If you get bored reading my old rubbish, you can key *prestel# for just a very few pages that might bring back memories.

    Plenty more saved stuff, somewhat more accessible, at www.viewdata.org.uk

    I have a couple of VTX5000s myself, must get one out of the cupboard and try dialling up!
  • edited June 2012
    Does anyone know where to obtain a ribbon cable to connect the VTX 5000 to the Spectrum? Or maybe how to make one? I would like to test mine and dial up with it. :)

    As I remember, there wasn't anything unusual about the cable - the connector on the back of the VTX5000 is basically a one-to-one copy of the expansion connector on the Spectrum itself, all the ribbon cable did was connect the two together, as well as offering a third pass-through connector for attaching any additional peripherals onto. I have a few here somewhere, I'll try to take a picture..

    (Don't take my word for this, though - I‘d hate to be responsible for any fried Spectrums!) :)

    The teletext adaptor (the TTX2000S mostly sold by Volex but also originally designed by OEL, I believe) used the same principle. Sadly I sold mine in the early 1990s - bit of a mistake, that, but I needed the cash at the time, mostly to pay the hideous phone bills being run up by my newly-found Micronet habit.

    It was said that the standard ROM of the VTX5000 modem made it incompatible with the 128K toastrack machine, (could be swapped for a custom ROM that was compatible) but I'm sure I rememberer mine working with no problems. Then again, my 128K machine was repaired by Currys and actually seems to have an Amstrad ULA in it. That might also explain why some other peripherals I had like the Rotronics Wafadrive either worked or didn't work when they should have. Hmm.

    Found a picture here at WoS, and you are definitely right: ftp://ftp.worldofspectrum.org/pub/sinclair/hardware-pics/PrismVTX5000Modem_56-waySplitterCable_1.jpg

    That's the one! The top connector went to the Spectrum, the second to the modem.

    Arrrgh! Haven't had much luck at all so far - dug out my remaining rubber-keyed spectrums, found the only thing close to a proper TV lead, plugged in and set the TV a-tuning.. Couldn't get a sausage from the 48k issue 3, but hit a fuzzy picture from the 16k issue 2 - which was OK except it resets the spectrum on every keypress, so obviously something up there.

    Tried hooking the VTX5000 to the 128k machine out of optimism, and remembered that it definitely didn't work - or at least not without hours of connector re-seating and resetting. Bah.

    Think I might have to buy a new Spectrum! I will dial up Rob's BBS if it kills me. :)

    If I remember correctly, the VTX5000 wasn't compatible with the Spectrum 128K. I remember one of the magazines was offering them for free (providing you covered the postage), but Spectrum 128K owners had to make a modification to the Sprectrum 128K's circuit board. I don't remember the exact details, but I do recall having to solder a wire from one section of the printed circuit board to another.

    It was scary stuff, because I was anxious that I would damage my precious Spectrum. Thankfully it all worked well and I enjoyed the wonderful world of Pretel and Micronet 800 with my Spectrum.

    I remember paying 1p for every email I sent in the early 90s. Great fun!
