The 6400 Zone is created to help you gain access to useful software updates and great shareware programs that add functionality to your system. It is also a one stop road map to other informative sites for answering your questions. Most of the info here is geared towards the 6400, but it is useful for all PCI Performa models and even the 6500 and all-in-one Macs based on the same. It's even useful to other MAC systems. I will be referring to my 6400/200 clocked to 220Mhz as just 6400/220, OK.

I will keep it updated as often as I can but I don't have much free time to work on it, so I suggest you check back at least once a week. That should be sufficient. If you don't see something you would like to see here or have your own software / web site that would benefit the MAC community, please write to me at TMK12v@aol.com and I will check it out.

Just Updated 11/19/1999

Happy Thanksgiving! I thought I would say it now because my relatives are coming out and I might not have an update next week? Should be back to normal the following week :)

6400/6500 Take Apart manuals: I just checked the link I have posted last week and it still works! Infact Apple has PDF manuals for the new iMacs, PB bronze, iBook, and G4's! I just downloaded them all :) The iBook does not have a take apart section in it but it does have some good info. As before look for the largest file and that will contain the entire manual. if all you want is the take apart section then download the one with the ending ".ta.pdf"

Sonnet Clocker update: Well since I had posted it only 300Mhz Sonnet G3 users are able to get it to work. Not one 240/250Mhz user said it works :( I am still waiting for a reply from the author on whether he can fix it or not?

Bill was able to get his 300/512k card to clock to 350Mhz! Very impressive!

Jason would like to know if there are any Sonnet 400Mhz owners out there that can try their card on a 6400 and use the Sonnet Clocker utility to fake it to run at 400Mhz in a 6400? I must remind both him and others that the G3 used in that card is only an 8x CPU which means theoretically it can go no faster then 320Mhz in the 6400. I don't think telling the clocker app that you have a 50Mhz system will bypass the hardware limitation? But if any one tries please let me know.

Update on Speculative Addressing and L2 G3's: Anton wrote a lengthy letter to Sonnet about why they do not turn Speculative addressing off for our L2 G3's when all the other G3 vendors have reports stating that it must be turned off on older Macs! Their reply is rather strange in that they say it is off? Not according to PowerLogix's Cache Utility though. Check out my Hack the Crescendo page to find out how to turn it off using software. Not as good as hardware but it might help :) Thanks Anton

Vimage update: I have been getting some info from people on other ways to get Vimage products. I will be trying these routes before I post any info on them to be sure they will work. Thanks guys for all the help.

Newer 300/1M L2 G3 user letter: Craig wrote to let us all know how well his Newer G3 is running. Thanks Craig. Click here to read more Newer User letters.

OS 9 and Vimage not working for some?: Stephen was unable to get OS 9 to work with his Vimage G3 even though some other were? Any ideas for Stephen? Thanks.

I do have a link to Interware of Japan which does have the final drivers for the Vimage cards. Please see my previous Just Updates. Also check out my OS 9 info page for more details.

OS 9 on the 6400, My opinions: A few people have noticed that I have not upgraded my 6400 to OS 9 yet so I thought I would tell you why. I do have 2 6400's but for now only one is running as the other is being readied for sale (I hope). Also the 6400 still running is my big boy system with all our software and peripherals attached. My wife uses it heavily and cannot afford to have it down to long as she needs it for doing MOMs Club work . Shes the president of the local MOMS club out here (A club for stay-at-home-moms to give support). Also RamDoubler and SpeedDoubler are not OS 9 compatible yet and I need at least RD so I can play all my games. 136M is just not enough for games like Unreal that demand 100+M to run normal. Now also top this with the fact that The Version of Nortin I have is not OS 9 compatible either which means no HD utility to fix any problems. And this is no problem for me but Geo modem users have stated the modem works but you cannot access the express modem control panel any more?

All this combined is keeping me from upgrading to OS 9. I am running OS 9 on my personal PB G3 right now though and it is running fine. It has 192M RAM so no need for RD :) Losing SD is not too bad but not being able to use Nortin kind of stinks. I know your all waiting for my personnal experience and I will try it but just not right away.

More mother board swapping: Here is a letter I got from a person that swapped a 5260 mother board with a 5400's. Thanks.

Another OS 9 user that has the Geo working: Darcy wrote to let me know her Geo modems basic features are working fine. I asked if she can access the Express modem control panel and should have a reply soon. Thanks Darcy.

Gaming Info ---------

Apple has released OpenGL 1.1.2: Click here to download it. I didn't notice any improvments on my systems as most of the ReadMe states it has fixes mostly for G4 AGP systems. Oh Well, one can always hope :)

Quake3 DemoTest is released!: id software just released the Mac Version of the Q3Demotest. This is the next version of the soon to be released Quake III Arena. It does require Apples OpenGL 1.1.2 so get it also. It is much more CPU intensive and Ram hungry then the previous version and barely runs on my PB G3 233 with a RagePro. I have to have most all affects turned off and low texture details but I can play if only a few people are on. I haven't tried it yet on the 6400 with the Voodoo2 but it should run much better. One tip for Voodoo card users is that you might have to remove the OpenGL RendererATI extension as some people have reported that the game will try to force itself onto an ATI card if one is installed unless you remove that extension. Ths was not the case for the previous Q3T versions.

Voodoo3 and G3 Upgraded 6400's: Here is a clip I got from Mikes Accelerate Your Mac web site. Seems he has had only Newer G3 card owners report good news.

Here is a letter from Kamen who also states the Voodoo3 and Newer work together. Thanks Kamen

Reply to letter I wrote to ATI about their VR card: I wrote a letter to ATI about the issues I found concerning Vimages G3 and here is their reply. Hopefully they will look into the problem?

Horror story about Vimage and ATI VR128: I think this is not the norm but Claudio wrote with some about an awful experience trying to instll the VR card. Thanks Claudio. I did try the VR card in my 6400 and got several crashes durin ght process of testing it but di dnot have anything this serious happen.

Just Updated 11/12/1999

You may not have noticed but I enlarged the standard viewing area of my site from 520 to 580 pixles wide. It should show fine on 14" and larger monitors. I was getting constrained by the size I was using before. I assume most of you have at least a 14" monitor :)

Sonnet clocker update: I have gotten several replies from Sonnet users on how well this utility works. It seems that the Sonnet 240Mhz users are not getting it to work but the 300Mhz users are? I emailed the author and hopefully he can find the problem? Here are a few letters I got. Thanks all.

Note as of this posting all 300Mhz cards seem to work and 240Mhz cards don't? Also the backside cache on the G3 will speed up as it is a direct ratio of the G3 CPU's speed so its probably a good idea to turn off any G3 cache utilities that might speed it up even more! I know the author of this utility is keeping himself secret AS he is the one that broke the code so to speak. There is no way Sonnet can track any user of this utility and all you have to do is replace the modified Crescendo extension with an original version and the mod is gone. No way to tell it was ever used.

Please keep the info coming in, specially the 240Mhz card owners. we need to find out why they aren't working?

Update on ROAM and the Sonnet G3: Ken writes that this is the first fix I posted that actually fixed his startup crashes! Cool, Glad it worked :) Thanks for the info Ken. Click here for more details.

Using the sharware control strip G3 Throttle to fix issues caused by a L2 G3 upgrade: Kees writes that using G3 Throttle, a control strip utility that lets you slow your G3 down by creating wait states for the CPU, actually made his Geo modem work again. Thanks for the info Kees.

Vimage L2 G3 not dead in Japan: Well Vimage may not be selling L2 G3 upgardes anymore but their parent company Interware is. Interware is the Japanese company that actually makes the G3 card and Vimage was the US distributor. I found a link to a final release of the 1.1.0 driver for both the 240/320Mhz G3's. The link is below.

Also Jordan sent me a link to a page on their site for a 400Mhz L2 G3 for all configurations of 6400/6500! Thanks Jordan. It is all in Japanese but you can make out most of the links as they are in english as displayed at the bottom of most browsers. Below is the link.

If anyon can read Japanese and get me a mailing address or an email address I would really appreciate it. Maybe we can buy direct from Japan? It will probably be more expensive but worth a shot!

Power Logix stops production on L2 G3 cards?: I heard from several users that PL will not be making their L2 G3 cards now so I emailed them and here is the reply I got.

I asked if he ever got an answer to let me know. I guess we're back to Sonnet and Newer only again :( OUt of these my choice is Newer as it is much more stable and hasn't had as many complaints but it does have a more serious Geo modem issue as many people get a port busy or some other port error.

Update ATI VR 128 and the Vimage G3: Well I tried my VR card last week as I mentioned before and well it just doesn't work. Below is a letter I wrote to ATI asking if they can find a fix. I know its not their problem but they might just help?

Update ATI VR 128 and the Sonnet G3: Well this combo seems to work much better. At least it boots :) Looks like thVr card has some issue ATI has to deal with. They even had almost another year to iron out the bugs! Thanks for the info Henry.

Update from Henry on getting 640x480 video capture to work.

Update Voodoo3 and the Sonnet G3: Here is a letter from one 6400 user that has the Voodoo3 running and with a Sonnet G3. Also note fix he has for the boot hangs. Interesting! These video cards sure don't play nice. I can't tel lwhat systems they will or will not work on?

Simple Launcher: This utility lets you assign the Function keys on your keyboar to launch apps and do some other thinkgs. Good for OS 9 users that can't use SpeedDoubler for this anymore. Click here to go get it.

Apples 6400 Take Apart Manual found!: Paul found a link to where Apple is hiding these manuals for me. Thanks! Remember to scan down till you find the largest file for the particular Mac you have and this will be the one with the full manual in it. most are very large like 5M or more. The littler ones are only part of the bigger manuals and they usually don't have the Take Apart section in them :( Here is the link for the 6400/6500 manual. Just delete "powermac.perf_6400.6500.pdf" to see the entire list.


Just Updated 10/21/1999

Request: Yann, who owns a 6400 with Sonnets G3 and has a Voodoo3 card, could you please email me. Thanks

Just Updated 9/24/1999

The 6400 Zone's new Home Address: Well I haven't actually moved my web site but I did make a new home address thanks to all the replys I recieved on how to make a redirect page. My new home address is:


Its not much different from the previous home address but it is much nicer on older Macs with slower connections. AOL has been placing ads at the top of my home page for some time now and I have always hated it! One of my readers found away around it so the ads would not appear but typing the long address (or even remembering it) was a tough job. Now thanks to you out their who helped me, I have made a page with a similar and easy to remember address that when called on just redirects you to my real home page but with out the AOL ads :) This only takes but a few seconds longer on the first link but now visiting all of my other pages will be much more enjoyable without having to wait for those ads to appear. And as a benefit, I can have my sites name in the address :)

Don't worry though if you forget this address, the old address works just fine but with the ads showing :(

CD containing the 6400 Zone plus past history for sale 9/3/1999

I was wondering if anyone would be interested in purchasing a CD with my entire up-to-date site as well as my 6400 Take Apart manual plus many of the past Just Updates included? I think this would be a great idea for anyone who hasn't been able to keep up or never saw my site until recently. Also for those of you with Sherlock the CD is even better cause you can tell Sherlock to index the CD and then you can do a search on any topic and if I ever talked about it, you'll find it! I have info as far back as mid 1997. I'm asking $15 which includes shipping for US residents (not sure what the price for international shipments would be yet?) and I will even include a few surprises! To make this offer even juicier I can add some download that you've been trying to get but just couldn't for some reason. Lets put my cable modem to work :)
