I've got that sticker in the Zip-Loc file along with the Sonnet 1400 Philips Screwdriver, docs, box cover, etc. I bought the CrescendoPBG3-466-1M back in May '05 for $299.95 direct from Sonnet. Does yours have the 1M or 512k L2 backside cache?
From Nov. '04 until I got HP_Mini in April '09, running Beater on the free Wifi downtown was my only way of getting online for posting here. The speed increase of the G3 and upgrade to OS9 made it a lot more pleasant experience after that first 6 mos.
