Yo, smiggy, i have Beige G3 MT that was 266mhz, upgraded w/ XLR8 G3Z, 640mb of RAM OS 9.1 LE 5.1.1, Voodoo 5500 pci video, Iomega Ultra C SCSI, 2 9.1g 10k scsi,1 18.2g 7.2k scsi, DVDRAM, CDRW..... As you can see my PT rigg is not even close to being supported but i can record 18 tracks at once, and get 24 track playback w/ at least 15 plug ins, all low cpu tho..mcdsp, q10. ren comp, maxim, 1176(just-1!!) and varois others. I rarely get that stupid error.
But, are you recording at 48k? Are you using the ADAT I/O? Are you recording on your boot drive, or IDE, or SCSI? Have you followed ALL, and I mean EVERY SINGLE suggestion in the quick start guide? No platinum, uncheck smooth all fonts, use chicago fonts....ect? I have a SUPER trimmed down extension set also. Tell me more about HOW you have your Beige g3 setup. sdf
