Take a look at the nubus-pmac project on SourceForge. http://nubus-pmac.sf.net/
The Performa 6300 is listed as a supported model. Since this is a NuBus based Macintosh, it doesn't have OpenFirmware (which is only on PCI based Macs). This would explain quite well why it ignores the request to get to an OF prompt. Also, yaboot wouldn't work on something this old anyway. The only Macs supported by yaboot are new-world models, of which the original iMac was the first.
