From what I have read it is the infamous "calendar error", but I have changed the crystal and meassured the 5v on pin 14 from the D4990, what else could be causing this?
Wouldn't be possible to skip this calendar error by installing a multibios?
Have you tried burning an EPROM with the diagnostics BIOS? it uusally helps with this king of strange issues. If you need help with it, I can help you.
Regards.
Try another 32.768KHz crystal or two, I find those are often the most picky part of fixing the green screen issue.
My Vp-390 is toasted so I can't do any memory programming.
You'll never know for sure without an oscilloscope to check the crystal.
I can burn the EPROM and send it to you, unfortunately the shipping cost alone would be about $10. Funny considering how close Colombia is to Uruguay. If interested, let me know.
Regards.
Neogeo hardware.....what a pile of crap, another board died on me today, now a MV1-FZ with this stupid calendar error, this board was working fine until yesterday, anyways I'm giving these for free to anyone who wants them, just pay for shipping and its yours, both the MV1-FZ and an MV-1.
Lol, I'm not angry, I'm just tired of these things dying on me for no aparent reasson, and believe me, I do take care of my stuff, and as I already said this thing was working just fine for like a month since I first left it installed in one of my cabs;
I'll get shipping rates to Colombia as soon as I can, which one do you want? MV-1 or 1FZ?....both??, I don't know if you have ever seen one these in person but for being just a 1 slot mobo the MV-1 is quit big.
Set all the DIP switch down.
What reports an error?
Cool man. I'd prefer the MV1FZ, because as you say, the MV1 is quite big, and I've also read it has compatibility issues with some games.
Thanks!!
With all dipswitchs on it only shows "Work Ram Test"
According to the AO wiki a MV1FZ weighs 750grs. so things goes like this,
Small Packet certified: $30 USD
Standard Mail: $25
EMS: $55
Express International: $62
we are assuming that the mobo once its packed inside a cardboard box does not weighs more than 1 kg, these are rates for "rest of America" as the Uruguayan post service does not have specific rates for Colombia, unlike Argentina, Brazil, Paraguay, Chile, Bolivia and Venezuela which have cheaper rates.
