OK, thanks for the advice. Of course Tiger isn't actually
fast on a 1 GHz G4 & Rage 128 PCI running on 50 MHz async RAM, but it's very usable.
Leopard was just appealing to the sportsman, being the last PPC OSX and possibly running on an ancient machine - but apparently I better not trash my Tiger setup then. Maybe I'll try it on a spare disk though.
I bought the Crescendo PCI directly from Sonnet, but it's been sold out since. Actually bought two and sold one for a very good price on ebay to an extremely pleased customer. That card was regularly 350 € here in G - when you could get it. I'd even have imported some more if Sonnet hadn't run out of stock.
I've also acquired a set of 128 MB DIMMs for that machine (5V FPM/EDO being extremely rare) at a decent price - half of that's still waiting for ebay...
