Well, it seems that NOTHING wants to run on these machines. I hate to say this, but even the old PC 386 and 486 machines will still run. There is still software out there. Slow? Yes, very, but what the will do, they do well.
Don't get me wrong, I'm not giving up on my T-Rex (minitower G3-266) and my Raptor (iMac G3-333). I still have uses for them. I'm just gonna hunt harder for something that will work with them. But it does seem odd that there is so little available, even in archives.
