DIP switch settings for Mac to VGA adapter

Click the link. It's hosted on imgur, not on 68kmla.
I see the link. It shows settings for the Viewsonic adapter AC-AT Mac II-02, which presumably was meant for a Mac II era system. For 1152x870 resolution SW 1-4 are all on. SW 5-8 depend on the sync method required by the monitor. Sync on Green 5-8 all off.
You need an adapter that supports "multi mode", aka multisync mode. This will tell the computer to enable a list of resolutions in the Monitors control panel. OS8 should support 1280x1024 in theory, but unless its a later PowerMac, it might not have enough VRAM to actually support resolutions that high. I know my beige Powermac G3 had no problem doing it.
I'll assume I008com's mac in question is the 7300 in their signature, yes?

Looks like the resolution should go up that high even with only 2 MB of VRAM (albeit at 256 colors...).
Another option, which might be a long shot, would be a Radius Pivot cable (at least that's what mine was hand-labeled as...), which is a standard DB-15 male to HD-15 male and no PCB trickery in between:
It's worked, plug-n-play, on every Power Mac I have (4400, PowerWave*, PMG3MT) connected to my Sony TFT display. The display in question might be the bigger X-factor in this case, however. From either control strip or the monitors control panel, you should have access to every resolution/refresh combo the monitor can handle (and in some cases more than it can handle...) Can't attest to any CRT performance, sadly.
*the PowerWave requires a PCI video card. The from-factory option (I think) was a Mach64.
