I use YAM. IIRC its the PPC compiled one, can't remember if its 2.4 or 2.5 though!
works fine, but the one annoyance is that I can't get it to display properly those pesky HTML emails people keep sending me ! anyone got any hints ?
I used to run YAM 68k (Definitely 68k!) on my 1200 at 800x600 on a Mikrovitek 1438s monitor, no problems there ! besides, it is MUI, so you can configure EVERYTHING about the display if you can be ar5ed!
