Thank you all! With those informations, I found out that this item is actually for Quadras and Centris 610. I'm a bit surprised : cooling is only made with a heatsink and a fan. I thought that 50mhz versions of this kind of accelerator required peltier junctions or other aggressive cooling methods.
Hi. I came into the possession of a 68040 based CPU upgrade similar to a Quaddoubler. Could somebody help me find out for which Quadra/Centris model it was designed? The "missing pin" is in the upper left corner, near the C24 mark.
Thanks.
Hi. I'm about to get hold of a Powermac G4 (Gigabit). I have access to OS X Server 1.2 install disk, which I successful installed on a Powerbook PDQ a few years ago, but I just realized that the Gigabit G4s require 1.2 v3...
Is it possible to install version 1.2 on a Gigabit G4?
If not, is...
You could also check on the Natami website. It is a project aiming at building a modern 68k Amiga computer. The CPU is emulated within a FPGA and is 68040 compatible. I think I read somewhere that the performances where similar to a 100 (or was it 166?) mhz 68040, which is already quite...
Hi. These are the files that were on ftp://ftp.csua.berkeley.edu/pub/jwang/develop/... They don't include the AT&T manual.
I never tried the tools. You may try to contact Mark White, the developer behind mpegdec (http://www.jwgdesign.com/mpegdec/). He tried to make a DSP version of his...
It would be easier (!) to find a way the disable the clock-doubler of a Quadra Overdrive Plus, so it would run at the same speed as your bus (50 mhz) with 128k of cache...
There was a thread on http://www.nextcomputers.org/forums/ about a guy who made some radical changes to his Quaddoubler...
The heatsink is glued on the processor. I can't say I'm willing to try to remove it, clean the CPU, and then reattach it.
But, changing the fan seems to have solved the problem. It has been on most of the day without any problem.
Both fans are working. I'd be tempted to replace the heatsink/fan on the Quaddoubler, but its somewhat glued on the CPU.
EDIT : I replaced the fan of the CPU heatsink with one twice as powerful. So far, it seems to have solved the problem (no crash for nearly one hour while playing MP3s and...
I'm having some problems with a Quadra 660av I left unused for a few months.
When I turn it on, it crashes after about 15 minutes of use. Sometimes it simply freezes, sometimes I get an error message ("bus error" or an other one) with the "restart" option (clicking restart won't change...
