I just found this, which would indicate that only the DOS models can go to 196 MB (4 on-board + 64 SIMM + 128 SIMM): http://www.micromac.com/products/bigsimms.html (They also claim their hugely expensive 128 MB SIMM works in the Q605, as Michael said.) > It looks to me like you have to use single sided cards in the second > slot and double sided in the first, and neither likes double banked > (wide) one. problem I had on ebay was often it says "may not be the > exact picture". even the memory companies on their own sites do this. > > so anyway the parts i got i do not have to look at yet but on the order > reciept it says: > > 128MB Apple Performa 630 Series 72-pin SIMM (p/n APL72P128) > $49.98 1 $49.98 > 64MB PowerMac 6100, Performa, Quadra 72-pin SIMM (p/n > APPLE-64MB-FPM-SIMM) $19.98 1 $19.98 > > (I think I spent too much) Well, perhaps not if we can fix xorg ;-) > > > i have tried X and i got some initial screen but it is only about > > > 2/3 of the way down and then it is overdrawn or something (whitish > > > color with stripes) and hangs the console.

(it speeds up the old machines quite a bit). Yeah, 8 bpp can be really slow on some macs. I never did much testing of different video settings on fbdev though. But ISTR that 4 bpp worked on some of my macs... Was this a regression in linux 2.6 on your Q605/sarge box? Or does neither the 2.2 nor 2.6 kernel support 1 bpp or 4 bpp fbdev (on either mac)? -f > I should try the 605 though because i found i am able to get 1024x768 on > that but only in 4bit unless I add vram. i don't know maybe that is > another regression if i upgraded i would lose the 16bit support ? it is > not costly though like the other RAM. it would be nice actually to put > the VRAM in to get 8bit at 1024x768. it is nice even in 4 bit. anyway I > should try that is is simply a matter of copying the 630 install to a > spare external drive, and hooking it up. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
