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 ...

220uF/4V connect to Pin 43 of the Bt473PKJ is Vref and GND ... I wanted to desolder the old one and measure it, but that didn't work, so I had to unscrew it. I ordered a new one, but I quickly soldered in a 220uF/25V capacitor in. The malfunction didn't change, though ...! All solder are very...

Yes I think so too, it is a 220u/4V one. All other are Tantal.

The video output is faulty. I'm not sure if it's a hardware or software issue? If I play around with the control panel and change settings, then restart, it suddenly works fine. Then the next time I start it, it malfunctions again. Apple Quadra700 running at 32 MHz and GrandVimage control panel...

I check as good ... - all Data and Control connections to and from the four 74ALS245 - all RAS, CAS and WE connection from the VGT8002-6215 to the 1MB Ram Bank - all Data connection from the 74ALS245 to the CPU - all Address lines connection from the VGT8002-6215 to the Ram chips I couldn't...

The computer has been stored away for a few months. Now it's making a chime of death. I've checked all the connections from the ALS245 to the four RAM sockets and on the other side to the onboard 1MB of RAM, and everything is fine there. All ALS245 are new ones. 74ALS245 all Pins1 -> (R/W) CPU...

No I expand the Zip File onto the Quadra and it do also not have a Resource Fork ...

Can I use this Romdump under MacOS7 ...? Download under OSX (macOS M4 MacMini) and copied via ftp to my Quadra 700 and it can't run because it's broken?

Thanks ... Is there a ready to use binary file from the SlotsGrab Tool? I can not compile it ...! When I have time I read the three links ...

... is there a program that runs under Mac OS to read the ROMs of Nubus cards and save it to a file?

There is a IC10 EEPROM "NM93C46M8" so I was thinking that must be updated to the 21B Version of the card ...?
