A/UX on a Quadra 605?

[fegos]

Hi all, i have replaced my Q605 CPU with the one i had in my broken 840av. So it is running at 25Mhz WITH FPU. The Q605 is not listed in the compatibility list for A/UX. Is it dead in the water or is there anything that can be done to install it with some workaround?

afraid not: there are missing drivers for hardware in the 605 in A/UX, so even if you can con it into booting, you can't see anything or interact with it in any meaningful way.

that's a bummer....thanks a lot!

Off topic somewhat but 25mhz is slow for one of those, you can get it running at 33mhz with this simple mod: https://lost-contact.mit.edu/afs/um...g Page :c4/Clock Chipping Home Page/q605.html

Agreed. 33mhz is such a big speed bump for these it almost feels like a whole different machine.

well yes, that is on my list. I will do the overclocking. I also happen to have a one of those QuadDoublers, it runs but it gets very hot (this one does not have a fan, just a heatsink) and after a while the computer crashes....guessing some sort of temperature protection
