    After an ominous couple of days when the placeholder landing page disappeared and I was just getting 'site not found', Atari-Forum is BACK!!

    I did read somewhere since I posted (unconfirmed, unsubstantiated) that the sysop was preparing to move it from its current host to a new host. Let's hope it does reappear some time soon.

    Atari-Forum down?

    Does anyone know what's happening with atari-forum.com?

    It's been 'down for maintenance' for well over a week now (May 21st 2020 as I write this).
  4. If you can get to grips with a free PCB design...

    If you can get to grips with a free PCB design package like 'Kicad', the output that program produces can be emailed to any number of PCB makers in China who will make you a little batch of them for...

    Right, so it captures the data which is being sent to the YM IC on your sound card, rather than the sound coming out of the YM chip, yes? And then presumably some bit of software can then replay the...

    Probably not, since you make them sound so exclusive, so perhaps you'd like to explain the difference between one of those and a genuine but otherwise common or garden Adlib sound card?
  7. You could try 'crowdsourcing' recordings of other...

    You could try 'crowdsourcing' recordings of other Adlib soundtracks to add to the site. I would assume that they would have to have been recorded from real Adlib hardware rather than from emulation...

    Nasa@, you obviously were logged in otherwise you would not have been able to post the above. If you have newly joined the forum your first few posts are held back to be looked at by the moderators...

    Mentioned in #2 above, 'Dune' :) Also mentioned above, 'Lost Eden', same software producer, same Adlib composer as Dune.
  10. I've always liked the AdLib sound and often...

    I've always liked the AdLib sound and often prefer the Adlib version of a soundtrack to, say, the MT-32 (MIDI) version. Stephane Piq's Adlib / SB Music for Cryo's 'Dune' and 'Lost Eden' were great...

    In spite of what you say about shielding this sounds like crosstalk between the audio cables and video cables. When you say the cable is shielded, do you mean that the cable has an overall screen...

    Hello Abruno17, Brit here.

    You seem to have been met with awed silence on this subject.

    Although I was in on the height of the UK home computer boom and still have my original ZX81 and Spectrum...

    Thanks for reporting that fix, I will convey it on to others who have mentioned the problem.

    If you wanted to make it virtually invisible you could possibly take out the reset switch and hide an...

    Is the key to this maybe that there are noise spikes on the +5V line and these are travelling into the 74LS04 gate input initially while you have the button pressed, then through C6 during the...

    My MK14 is to hand at the moment so I have measured the voltage on pin 7 (NRST) of the SC/MP when the reset button is held down

    -An impressively low 0.07V. Bear in mind of course that this is...

    Agree. I think there might be some more 'dynamic' aspect to the chip-provided reset, rather just the voltage. I don't suppose you have a storage scope, Lurch?

    I wonder if there is anything in the...

    Thanks for trying out the power supply theory, sorry it did not help.

    How about trying an 'original' 7404 as U18, or even just a pulldown resistor (value to be determined by experiment) on the...

    There have been several people who have built MK14 replicas and have reported poor manual reset action - and this is not just the Czech / Martin L replica like Lurch's but at least two people with...

    There were also numerous microprocessor trainers / development system projects featured in hobby electronics magazines. In around 1977 'Elektor' featured an SC/MP based microprocessor project that...

    In the UK we had the 'Science Of Cambridge' MK14 which was SC/MP based, a kit aimed at hobbyists. That machine was actually derived from a functionally similar kit which had been available in the...

    Just spent a good 45 minutes hunting around in all the likely places but can not find it - I can even visualise it still in a bubble pack with a foil back, but what I have done with it I don't know,...

    I'm sure I bought a 6402 a couple of decades ago to use as the basis of a MIDI project, but then discovered microcontrollers and used one of those instead. I'll have a hunt around tonight to see if I...

    What sort of device is the UART? Z80-SIO? Z80-DART? 8251? 6402? It's possible I may have one or more of these lying around.

    Hi DA52 -

    Stuck non-character key on keyboard, possibly? I don't know these machines well so I don't know if it would be trivial to disconnect the keyboard?

    With regard to the failed disc...

    Hello Ruud. I hope you found the files you were looking for.

    I have, not the ALL-03 but the All-07.

    If you mean that you have information on how to make custom device files or to control the...
