I've been watching it on the discord (as well as the PicoMEM that I have) and it's moving so fast. Lots of problems are being found and dealt with and every time that happens the project is improved for everybody, becomes more robust etc. This might be the project that everybody goes for in their …

New RAMDAC chip arrived... and I was right. Problem solved. Output is now white and the error code is gone from POST!

301,161,601,163 And 2401 are the error messages and it's the same with the VGA cable connected, or disconnected. 2401 is the one that relates to VGA.

PIST does report a VGA problem, yes. But at I've said I've thoroughly checked continuity right from the port to the ramdac IC and used an entirely different monitor and vga cable

Fantastic! I'd been told putting one in would work but this gives confirmation. It has 3 ISA slots which is probably 1 fewer than I would want if I'm using a VGA card but I think I can get it to work. However my top preference would be to get the onboard VGA working, if at all possible so I'm open …

I've bought a Model 30 286 on ebay, it's come with only 512K of memory and no floppy drive. It seems to missing the green component from RGB. I've changed monitor and VGA cable. I've checked continuity from the motherboard socket to the Inmos IMSG171P-35 RAMDAC. and checked continuity on the cable …

There's also a podcast that has much less subscribers for some reason that features Neil from RMC Cave which …

Yes so originally I bought a 6MB voodoo 1 card. The reason was that A) it matches the era better and B) it avoids any problems. Now that I've learned that there actually aren't that many problems and seemingly all can be avoided I thought the v2 might be a better option. The MMX range came out in …

Ok... perhaps I can get a bit more advice here. I am happy to use D3D cards where a game runs as well in D3D as anything else so my use of Voodoo is just for games where Voodoo is best. Previously I had come to a (I think the wrong) conclusion that the voodoo 1 was the best thing for me. I'm now …

I've been using a KVM for video output, I like knowing when it's the 2D or 3D card outputting video. I am now reasonably sure I've settled on what I want... I want a Voodoo 2 because I want to have separate 2D and 3D cards.

Yes, I have. This is on 3 out of 5 PCs. And it's on 2 out of 2 omiview pro KVMs. I have tried no monitor connected, I have tried the CRT connected and I tried a flat panel - same behaviour each time. The only way it works properly is if I switch to the "wrong" channel on the KVM before I power on …

I have an Omniview F1DA108P and other than one small problem it's ideal. For some reason 3 out of the 5 PCs connected to it will detect as connected to monochrome monitors if, and only if, the Omniview is selected to their channel when powered on. In other words if I switch on the PC in channel 2, …

Other than the memory size and voodoo type, is there any meaningful difference between manufacturers? In other words if I'm looking for a 12MB voodoo 2 do I need to take into account which manufacturer made it?

It may be the KVM. I've got 5 PCs connected to it. 2 have the mono issue and another detects a VGA connection as DVI-D, so I've had to use an active connector. But all 5 connected PCs are currently working with workarounds.
