I think the NEC Multisync supported sync on green but the Display say "no signal". I also use a ijyama or a Miro Display.

There is a LM1881N to convert C Sync to H Sync and V Sync ...

Pin4 = 5V Pin5 = 0V Pin9 = 0V ... have I connect Pin4 ?

GPU Pinout ...

I try it and make a Adapter ... 1 - RED 2 - GREEN 3 - Blue 4 - 5 - 6 - GND 7 - GND 8 - GND 9 - ... I test two Monitor a NEC MultiSync LCD1970NX and a MIRO LCD Model 568 but I don't get a picture via the MIRO graphics card. It do not work without any sync I think?

I'm a little confused. I don't want to modify the card like the instructions suggest. What would be the right VGA adapter without any modification? 1 - Red 2 - Green 3 - Blue 4 - n.c 5 - H sync 6 - GND 7 - GND 8 - GND 9 - V Sync

I plugged the card into my Quadra 700, and the occupied Nubus slot doesn't appear in TattleTech. Now I have to measure the card's 9-pin VGA connector first ... With so few pins on the 9-pin connector, surely there's no way to detect whether a monitor is connected to the card or not? VGA...

Looking for some divers to the "BMAC PRII 001" Graphiccard. It has a INMOS IMSG300G-10C Transputer GPU Chip on it and 1MB of VRAM. The EPROM Sticker say "PRISMA II v3.1" ... There are some sites with MIRO driver on the Web but these are wrong for this card. I can not find something ...

If I desolder the flash chip to read it and then reprogram it, I need either an adapter board to which I can solder the flash or a chip adapter. I could then populate the 32-pin DIL socket and use a flash chip in the DIL instead of the TSOP.

In addition to the 64k Flash, there's also an EEPROM on the card, a NM93C46M8. The first step would be to backup the original ROM from the 64k Flash in case something goes wrong. I don't know if that's possible, but I'm populating the 32-pin DIL socket and soldering an adapter to my programmer...

110Mhz RamDAC ...

The new SMD capacitor arrived today, and I soldered it in right away. These SMD capacitors are pretty rubbish to solder in manually, but I wasn't sure if a Tantalum capacitor could have been used? Except for the one for the DAC reference voltage, all the capacitors on the card are Tantalum...

I built my own video adapter with separate sync and IDs set on a 21-inch multisync monitor. That was the problem. I'm now using a purchased adapter with the sync-on-green setting, and everything's fine now.

I try the card in a IIsi with System 7.1 and it has the same fault ...

I ordered a new 110 MHz RAMDAC to try out. I'm also thinking about updating the ROM with the version from a 24-21 card. There's a soldered-on flash, an AT29C512 (64kx8). If it's large enough, I'd build an adapter cable from the 32-pin DIL pins/socket on the 21-19 card to my programmer, back up...

I will make a Test Adapter without the Green Signal to see if Sync on Green is the Problem? There is no english GrandVimage manual ...

May be I buy a new RamDAC chip but I think this do also not help ...? The PLCC SMD Socket is bad, this type of sockets are always bad. Which bends in the middle see the picture, but it do not the problem I think ...

Yes It do not help.

The Monitor is ok it is a NEC MultiSync LCD1970NX. It is good with the Quadra Onboard Video, a Performa 475 and a IIsi with a Radius Graphiccard. I can test a iiyama LCD Monitor ... I'm pretty sure it's a software issue. If the image is fine and I switch from the default 1024x768 to 832x624...

Monitor Signal is faulty but the Screenshot is ok ...
