    I got mine working yesterday. I didn't get to test much, I used a fritzy console. I'll need to swap over to a less crashy board for further evaluation.

    Hey guys, would it be at all possible for me to buy a couple of UltraVGA boards? I was out of the country at the time the spreadsheet went up, with extremely limited internet access and could not have possibly added myself to it in time...

    The only way for anyone to get any more would be if @marshallh made some more

    To do low volume (1-10) costs around $85-100 each. I can only get the price down if I get more people together again.

    Well I'm definitely interested in a few as well. Maybe we could start to gauge interest again?

    I know I can order at least 4 of these if given enough notice.

    Sign me up for 2 when/if they become feasible again.

    Sorry to double post but I'm still very interested in obtaining an ultraVGA. Given it's been a month since my above post, I just wanted to chime in saying that I'm still hoping to get one of these bad boys. Especially since I just got a new screen in from China that only accepts vga and composite. Maybe someone who bought multiple ultraVGA's can think about selling me one? Please? :oops:

    Maybe we could start another interest thread for these again? I'd be interested in one as well, if we had enough people to do them.

    @marshallh Just to double check my findings. This picture shows 17 pins on a 24 pin FFC spot. With my continuity tester and a 24 pin FFC to DIP this is the pinout I'm getting. NOTE: my order is inverted to the above picture see attached image.

    Pinout As Per FFC to DIP (Inverted to Ultra64 Image):

    01 CONT
    02
    03
    04 GND
    05
    06 VCLK
    07 GND
    08 /DSYNC
    09 D6
    10 GND
    11 D5
    12 D4
    13 D3

    Victory.

    Everything seem good except occasionally (every 1-5 minutes) the screen blacks out for half a second then comes back. This could be on my end and not the UltraVGA's fault. The only real issue I've found is the Bomber's Notebook is still a no go zone. From what I understand the N64 switches from 240 to a 480 when you open the notebook and Marshall was still working the bugs out of that one. When I open the Bomber's Notebook it displays perfect for a second then whites out.

    It should be fine - UltraHDMI eats mode changes for lunch since it was specifially designed for such. I would guess there is some other problem which is probably related to the screen blanking. A pin with bad soldering/contact will still work most of the time except for certain data patterns, etc.

    You could leave the OSD showing for several minutes and observe if the OSD also disappears when the screen goes black. The sum total of your wire length is probably on the longish end of what's workable.

    WTF so I decided to try Bomber's Notebook with the OSD up and it works flawless today. I will have to test further. All I can think of is maybe there was still some residual heat in the parts from soldering (I agree my wire lengths are very long). I originally tested literally right after soldering it together.

    Finished a solution for people using VGA, or who may not want to keep the bulky analog audio part of the N64 mobo.

    Name not final

    [​IMG]


    It wires directly to the digital "audio" produced by the RCP, which is sort of a special snowflake i2s-type hybrid. T he Max10 FPGA contains a fractional rate audio resampler to handle this, and a small cpu to control the combo speaker/headphone amplifier.
    All you have to do is wire up power, connect your speakers and a couple volume up/down buttons.

    I will probably get a group buy going for these soon, they should be pretty inexpensive.

    Sorry to bump a zombie thread but I figured this information is pertinent to the topic here.

    I've got this UltraVGA project that has been in limbo for awhile now. I've re-soldered the whole thing over and over again but no dice. The OSD shows no wiring problems under the [ABOUT...] --> [SELF-TEST DIAGNOSTICS...]. The only difference between this project and my previous UltraVGA project is under the [ABOUT] menu the N64 VLCK shows NONE and the current status on the bottom left would flip between 525-60HZ (P) and 525-60HZ (I).

    I just woke up in the middle of the night with the solution: the only difference between my previous UltraVGA project and my current one is the wire lengths. My first one is at one extreme with wire lengths around 11 inches and my current has wire lengths around 2 inches. I'm still getting data to appear under the B-CODE and P-CODE on the [ABOUT] menu so I figured the only problem is on the VLCK wire. So I added 5 inches of wire to the VCLK line only and the sync problem is solved. I'm sure you can get away with less wire length but it works now and I can continue working finally.


    Previous Project w/ 11 Inch Wire Length

    Current Project /w 2 Inch Wire Length and 7 Inches on the VCLK

    Hey everyone, sorry to bump this thread! Just wondering is it still possible to buy one or more of these boards? If not does anyone have an extra they would like to sell?
