One of the problems with them is really dud airflow. Part of the problem is that on the inside of the PSU is a mesh covering the fan. Give that a little dust and the airflow is cut down pretty badly. I threw that away a while ago.

There's also a pretty restrictive fan guard on the outlet of the fan on those PSUs too. I ripped THAT out also. Now this one seems to have really brought the machine up to well-cooled!. Not only is the whole PSU a lot quieter, it's also not all THAT much dangerous than it was. OK that sounds kinda bad, but really, the fan is pointing downwards. Works for me, and seems to let a good deal more air through.

With those two changes the cpu on a 6100/66 feels decidedly cooler. So there.

Impressive! Btw, Dana...slightly off topic question. How healthy is the mobo in that rusted out 605? Just wondering, because a few months ago, i found out the top of the processor card cage thingy in my iMac had rusted out, so I removed it. Underneath that cage was my 64 meg SO-DIMM which had magically died (that was the reason for having the iMac open in the first place!) Anyway, i'm not sure, but i reckon that some rust must've fallen onto the SO-DIMM, and shorted it out when i went to boot the iMac....i'm actually amazed that it didn't short the whole machine out!

I wonder if there's a way to make an 840av's HDD quieter. Because the loudest part of my 840av, when alive, was it's hard drive...

the PSU and it's innards when working alone, are actually rather quiet, but somewhat useless without the hdd

(What was that kind of flash/memcard memory that wasn't limited in the number of reads and writes?) (Maybe getting a scsi reader for that, )

I guess a $10,000 computer deserved high quality, quiet components!

Man, I've been noticeing all kinds of computer parts rusting lately. It seems like where you touch the bare metal parts of CDROMS and cases and things, rust forms in the pattern of the fingerprints. Eventually, it will probably rust through. I have enough to worry about with my car rusting out, now this! But seriously, has anyone else noticed this or am I going crazy?

Other than that, i haven't noticed too much of rusting with my stuff, but that's just my stuff

The only down side is that SRAM requires constant power or the data is lost. It's often used in devices such as Digital Cameras where Flash Memory, given the sheer number of photos a user takes on a stock model Camera, would easily give out before the warranty. (Most Cameras ship with 8-16MB, and serve as Web Cams with the ability to record video footage when powered on the battery, meaning disk writes are constant, and low memory means more stops to unload photos and more writes to memory)

SRAM cards do share a common trait with Flash Memory in that they do come in PCMCIA form and can be used to boot most IDE based systems.

Another thing, is that you can get blank cdromdrive bezels, and thus block out the noise caused by the hdd there, and that is farther away from any venting holes.

Maybe, it'll be Cory's Quest: The perfect 840av. (or not, seein's how I no longer have my 840av...)

 Maybe you could also try wedging some foam in between the bezel and the RF shielding. There is RF shielding in the 8100, right? Maybe even between the drive and the bezel. Don't go overboard, though, or else the drive could overheat.

You guys ar KILLING ME!!!!!!

You've got me looking at my 2300c with a crazed hackers glee YET AGAIN!

Somebody over on 'fritter was asking about adding cache to his 5300. In between researching the links in that thread, posting a response with the DevNote links for the 5300c with your advice on the SRAM cards after checking it here again, I've discovered that the 5300FAQ appears to be in error. The Baboon ASIC used in the NuBus PPC PB generation supports TWO IDE devices, that's likely why the 1400c can have an ATAPI CD and its IDE boot disk on the same IDE bus!

Baboon is the IDE ASIC in the 2300c as well! As if that weren't enough, the TREX PCMCIA controller could most likely be grafted onto the Duo's Docking connector if it's buffered exactly like the FDD controller and SCSI controllers are implemented in the MicroDocks. That gives me two different approaches for hacking an SRAM card into my 2300c to get a speed boost using an IDE<->PCMCIA adapter and possibly to attach a wireless network card!

YOU'RE FREAKIN' KILLING ME!!!!

6100/80 anyone?

Iff'n I had a 6100 or ten, I might try it

It makes me wonder how I'd be able to improve cooling in the 7300, and what opportunities would exist for enhancing it's speed a wee bit

Trash, do you like, need a bit pallete of spare duos? you sure like hacking them

Another interesting thought, IMHO, would to have a quadra 610 (the kind with ethernet ) with a full 40MHz 040 and overclock it a wee bit... maybe to 50 MHz (the max of an 040, right?) and then run A/UX on it. I would love to see a forum or a gallery running there

Which forum softwares are they? and will any of them run on CGI? I think it'd be interesting to see MacHTTP and it's CGI abilities maybe run a forum...

I also wonder how much of a mac it'd take to run something like that, and how fast it would be...

Even so, I would wonder how well a 68k would run a MySQL or oracle 7 or whatever database... (it can't be that bad, can it?)

If you think about the actual speed and instructions per minute that a 68K has, and what portion is taken my Mac OS, then whatever is left is cycled through video updates, disk functions, there really isn't alot left for other tasks.

I'm sure the databases will run fine, but it's a matter of how much load they can take. After a certian number of loads it just gets too much.
