• introducing minisound GS

    From Steven Wallace@21:1/5 to All on Wed May 10 17:46:44 2023
    minisound GS is a 16.5 mm x 82 mm daughterboard which plugs directly
    into the sound port on the Apple IIGS motherboard. A jumper cable brings
    12V power from the fan connector to the board. A daisy header on the
    board allows power to continue to a fan if needed. A headphone jack at
    the rear of the board provides the stereo output.

    A voltage regulator provide +5V and a charge pump -5V.

    If you email a request for a board, I will mail you one. Please provide
    your name and mailing address. If you like it, please send a donation. Otherwise, please return the board within 30 days. If not enough people donate, then another batch of boards will not be made.

    visit http://minisoundgs.sdwmail.org

    email request to minisoundgs at minisoundgs.sdwmail.org

    Enjoy!

    minisound GS replaces the functionality of a stereo sound card, except
    it isn't a card, it is a board and therefore saves a slot. In addition, because it is local to the sound socket, it eliminates crosstalk and
    resistance a cable would produce, resulting in a cleaner signal. It
    only produces line level stereo sound output and does not have the power
    to directly amplify an 8 Ohm speaker.

    Nice! Where in the world are you? Would you ship a board to Germany (if
    I pay shipping first)?

    Also, if I look at the pictures, you should definitely vacuum your GS sometime... ;)

    Yes. I emailed a request to Steven on 11-May-23, and the unit arrived at my home in Pittsburgh PA USA on 20-Jun-23.
    It is now 20-Jul and I am tonight attempting to install the board (yes I procrastinated) but am not having any luck bringing up Steven's website to find the instructions. I tried http://minisoundgs.sdwmail.org and also http://minisoundgs.swallace.org,
    which both resolve to minisoundgs.000webhostapp.com but I am getting "minisoundgs.000webhostapp.com’s server IP address could not be found.", does the URL work for anyone else, or do you also get the same error? I just emailed him to ask for help (Man,
    I wish I'd saved the web page as a PDF!).

    Chrome auto-retried a couple of times and eventually the 000webhostapp.com link went through.

    "Installation
    Insert the daughterboard by aliging the 7 pin female header with the sound connector located at the front right of the Apple IIGS. Press down from the top of the board (SV1) so as not to torque the board (use thumb pressing at right edge to avoid
    discomfort from soldered pins). Make sure the 7 pin female socket is aligned with the seven pins of the IIGS's sound connector, as there is no protection to prevent an offet. Connect the provided jumper wire with the red wire on the left to the fan
    connector. Connect the jumper wire with black to the left (indicated GND) on JP4 at rear of board. If polarity reversed will not cause harm and just wont work. Connect your fan making sure power is closest to the front edge of the board at JP3 (+12V and
    GND indicated). Connect your headphone jack at the rear of the board."

    Thanks Andy & Charlie! I think it was just my paranoid work computer blocking the domain name, I was able to open the page straight away on my phone. Installation went well, and the board is working now in my ROM03.

    I believe the stereo output is working as expected, but I only have some earbuds with me so it's not exactly a proper test. I'm running the game 'Silpheed' which I've read provides a good test sample of stereo music. Comparing the minisound GS to the
    built-in mono headphone jack, my impression was that the music sounded a bit more brassy / treble via the minisound. I also could hear a quiet high-pitched whine when there was no sound being generated, which I could not hear via the mono jack. I need to
    link up a pair of decent speakers when I get home from Kansasfest in a few days, before I form my final impression.

    The power pass-through to the fan works just fine.

    So somebody finally got one? I emailed him on the 12th of May, just a day after you dod and haven't heard or gotten anything from him. I was starting to wonder if it was vaporware. Should I email him again? Would that do any good?

    I got an email from him on May 13th, wrote back on May 14th that I want
    one. Then I emailed him again on June 8th, but no reply (and no card) yet.

    Maybe further emails will finally move him to act (or talk) :-)

    It would be a pity if this card just disappeared.


    Just sent another email. Will be interested if I get a response.

    Update: I'm definitely keeping the board, so I sent a USD $25 Paypal donation on 22-Jul. Last communication from Steven to me was on 11-Jul, to ask how my testing was going. I've written to him 3 times since that date - firstly apologising for not having
    tested yet, then asking for help when my computer could not access the installation web page, thirdly to say that I found the instructions, installed the board, tried it with earbuds but need to test more back at home through powered speakers. I also
    described how I'd been showing and talking about the board at Kansasfest, and saw a good degree of interest.

    Andrew, you were in touch with Steven to request some boards for the Ozzies, any success or progress?

    Steven, if you're reading this, a message from you in this forum would be appreciated, to let interested folks know what to expect.

    I contacted Steven and did get a response. He said he already has a mailing label printed out for me but I'll have to wait until Sep to get the board, that's when he'll have naother batch ready to go.

    Update: I'm definitely keeping the board, so I sent a USD $25 Paypal donation on 22-Jul. Last communication from Steven to me was on 11-Jul, to ask how my testing was going. I've written to him 3 times since that date - firstly apologising for not
    having tested yet, then asking for help when my computer could not access the installation web page, thirdly to say that I found the instructions, installed the board, tried it with earbuds but need to test more back at home through powered speakers. I
    also described how I'd been showing and talking about the board at Kansasfest, and saw a good degree of interest.

    Andrew, you were in touch with Steven to request some boards for the Ozzies, any success or progress?

    Steven, if you're reading this, a message from you in this forum would be appreciated, to let interested folks know what to expect.

    Need to correct the record a bit here ... I received a long email with photos from Steven on 21-Jul in response to my ask for help installing, but I only just found that message yesterday in my !@#$%*& spam folder.

    I received an email from Steven on 12/7 saying he was planning to send me “five boards rev 0.80 tomorrow”.
    Nothing further.

    I have received 5 mjnisound GS v0.8 boards today and will pass them on to locals and get into testing.

    I'm running the game 'Silpheed' which I've read provides a good test
    sample of stereo music.

    I tried Silpheed, but while there is definitely channel separation, the
    music is not a good stereo example IMHO.
    Instead, I suggest Bards Tale 1 title music.

    Comparing the minisound GS to the built-in mono headphone jack, my
    impression was that the music sounded a bit more brassy / treble via the minisound.

    I need to setup a test rig that allows easy comparison of this.

    I also could hear a quiet high-pitched whine when there was no sound
    being generated, which I could not hear via the mono jack.

    I will investigate this further. I think I hear a hiss. The output level is
    too loud for my headset so I need some way of turning it down.

    I need to link up a pair of decent speakers when I get home from
    Kansasfest in a few days, before I form my final impression.

    Have you done any more testing? Steven mentioned there were jumpers that
    could affect the output. Has he explained their use to you?

    Regards,
    Andrew

    I pulled out two ROM1 onto the bench and installed a MDIdeas stereo card in
    one and the MinisoundGS in the other. I hooked both up to a mixer and then
    out to headphones. I also hooked up the IIgs 3.5” jack (mono) to the mixer
    as well to see what the difference would be.
    The mixer was set to not introduce any variation into the channels so in
    theory it allows me to compare outputs quickly with push of buttons. The MinisoundGS is working very well, however I do hear a slight hiss in the
    left channel. However, I also can hear that the MDIdeas has a slight hiss
    in the right channel. I’d like to be able to visualise this better and am thinking about what gear to use.
    The whine coming from my original PSU is way louder than the hiss I can
    hear so this slight hiss not an issue that should cause anyone concern.
    The position of the 3.5” jack could cause the stereo cable plug to
    interfere with a card in the memory slot or slot 7 that uses the space next
    to the card edge. Ie the RAM-GS
    You can work around this by choosing a stereo cable with a thin plug, or
    using another RAM card if you have a choice.
    I next tried two ROM3 and compared outputs again. I heard the hiss from
    both cards on the same channels as before.
    Both sound cards sound brighter than the built-in jack and they are
    comparable to each other at the same level on the mixer.
