Funny enough it works fine in the M919. Posted a 20.2 in Dosbench Quake at 180.

But it goes black on the m919 after post at 33Mhz fsb, which is probably just the M919 being it’s normal unpredictable self. Not sure if the VLB bus is divided like the PCI bus on this board.

Update 1: it worked the 2nd attempt at 33Mhz FSB 🤣. And there is a divisor on the VLB bus. Hit 20.7 after doing the FSB jumper trick to force 1:1 on pci.

Recent VLB get, Number Nine Trio64, a 9FX Vision330 specifically. Lighting for dramatic effect. No interesting print on the back.

I have this card. It's a vision 330. Says so on the floppy disks.

Same bios and essentially identical, except yours have the 2 ram sockets, and they skipped it on mine and soldered directly.

Nice! Thanks for confirming, there’s really no indication on the card itself. Initial tests prove it’s a decently quick board for dos gaming.

Recently acquired this Diamond Stealth 64 VLB card, based on the Vision 964, but unfortunately I’m seeing corrupted graphics. Any ideas, possible to repair? I’ve tried cleaning the contacts and tried it on a couple VLB motherboards.

Recently one of the users here had similar issues.
Turned out to be a failing RAM bank.
Took swapping 3-4 of them before hitting the bad one.

Check for cold solder joints. Seems like 1-2 data bits are not coming through correctly. Maybe one or two pins on one of the memory chips are just not connected properly?

You may try to also press on each chip to see, if the problem goes away. But for that, in text mode, you probably want something that constantly rewrites the screen while you are massaging the card. 😉

Anyone heard of AGAtech or have any idea what these jumpers do?

I think one jumper for VLB-BUS speed selection 25-33MHz or 40-50MHz and second for WAIT-STAIT selection 0WS or 1WS

Is the "Assign IRQ to VGA" also relevant to VLB graphics cards? That might also be one of the jumper's purpose.
