And the damn thing doesnt even work in the Q800. The Sonnet QuadDoubler was a very clever hack with one significant drawback: It had to be specifically designed for a single computer. There was a 40/80 MHz model for the Centris 610, a 50/100 for the Quadra 610, and a different 50/100 for the Centris 650. Other ones for the Quadra 610, 660av, 700, and 900 have been discontinued. There isn't any good reason that a model designed for a 25 MHz Mac can't run in *any* 25 MHz Mac, except for physical fit reasons (like why the cache modules for the 700 won't work in a 605 with LC PDS cards installed), unless Sonnet specifically designed them *not* to work... Thus the one that works in the C650 ought to work in the 610s, 660avs, 700, and 900, but nothing is ever gonna work in the 800 and 950. -- the pickle FAQ http://macfaq.org/index.shtml _ -- Quadlist is sponsored by http://lowendmac.com/ and...

Re: QuadDoubler results are in!!!
They both had Ethernet on-board, and neither would benchmark faster in Speedometer. Er, not necessarily. Remember, the 4MB Centris 650 doesn't have ethernet, or a full '040. So, there's a GOOD chance that the board Dan has is the base Centris 650 board. -- the pickle -J -- Quadlist is sponsored by http://lowendmac.com/ and...

Re: QuadDoubler
Dear Quadraphiles: Sorry I'm coming late to this party, but this time of year is pretty busy for us clergy-types, so I've been behind on my e-mail. The pickle alluded to my experience with QuadDoublers yesterday when he wrote: If it has its own clock generator (where's Rob Johanssen when you need him?) then it should work just fine. The Pickle and I had a look over a QuadDoubler-type gadget (see below) last summer. QuadDoublers DO NOT have their own clock chips. They do exactly what the name implies, double the clock speed (bus speed) of the main oscillator. They have a little chip on them which effects this. The only gadget I'm aware of with it's own clock generator is something made by Newer Tech in the early 90's for the Q950, which will run that machine at 50 mHz. It has its own Motorola clock generator chip which is programmable to 1.33, 1.5, and 2.0 times the oscillator frequency. It also has what appears to be its own on-board cache. The CPU has an integral cooling fan on its heatsink. I have tried that in my 950, and it did boot and report a speed of 50mHz. However, I could not get it to run stably under OS 7.6.1. It brought up all kinds of strange errors, bombs and hangs. Furthermore, the software that came with it did not appear to function. I have always meant to experiment with backing the OS down to 7.5 or 7.1, and putting scrupulously tested 60 ns RAM in it, but this 950 is heavily used and I just haven't gotten around to that project yet. I've tried QuadDoublers in several different machines, with mixed results. I have tried running one in my Q950, and it's not a matter of overheating: the thing won't even start up. You just can't get that thing to run at 66 mHz. It will work in a Q700. I even put it into a Q605 for grins, and it worked OK there, though you couldn't close the case back up. It was kind of neat playing Doom II for an hour or so on that 605 cooking along at 50 mHz. I was glad to read of Dan's success with his 'doubler. I share his mixed feelings, though. It seems to me that the performance bump you get from these things is not worth the trouble or expense of dealing with them. If you can get one cheap (under $30-40) and don't expect miracles, go ahead. But the fact is that you can get a PPC upgrade for most Quads for $60-80 on eBay and really get a performance boost. In my opinion, the QuadDoubler is not much more than a curiosity. Pax, Fr. Rob Johansen -- A computer without Windows is like a dog without bricks tied to its head. Fr.

It is DEFINITELY a Centris 650 board. You dont need to double check, it will be a waste of time, because it is DEFINITELY a Centris 650. Anyway, Im interested in this accelerator that will work in a Quadra 950. Does it plug into the processor slot or the PDS slot? Chris -- Quadlist is sponsored by http://lowendmac.com/ and...

Re: QuadDoubler results are in!!!
Yes, the Centris 650 board with 50MHz 68040 you have seems to outperform a Quadra 800. However, a Quadra 800 can be clock chipped to 44MHz, or 48MHz if you dont need the serial ports. That processor speed combined with an equivelant bus speed, however, may outperform a 50MHz 68040 on a 25MHz bus. And though it would take some soldering, if you have the correct solder and a soldering iron, would only cost $5. That being said, you may be able to bumb the speed of the MicroMac to 55MHz, give or take. Chris -- Quadlist is sponsored by http://lowendmac.com/ and...

Re: Quaddoubler Problem
ORIGINAL MESSAGE: Anyone on the list have experience with Quaddoublers? I have a Quadra 700 I leave on for months at a time as an OpenBSD box doing some minor tasks, and I noticed when it's given very intense tasks (like for instance, today when I was compiling OpenSSH), it tends to have stability issues. I noticed the Quaddoubler pictured on Sonnet's web site does not have a fan, but a heatsink. For some reason my Quaddoubler has a fan attached, which doesn't seem to be cooling it effectively. Anyone think replacing the fan on the Quaddoubler with the original Quadra heatsink would yield better results? How about combining heatsink AND fan? This should, at least theoretically, increase the cooling. Let us know the results in case you try. Steff -- Quadlist is sponsored by http://lowendmac.com/ and...
