Merry Christmas and Happy New Year!

Sonnet updates drivers and lowers prices: Robert notified me that Sonnet Tech has updated the driver to 2.0.2 and lowered their prices on L2 G3's and are discontinuing the 400/512k version. Thanks Robert.

[Prices were reduced Nov. 1.

400/512 $179.95 has been discontinued and is available at Sonnet web store "specials" while supplies last.
400/1M $199.95
500/1M $249.95

The 500/1M has 250MHz cache. It runs at 400/200 in 40MHz bus machines. Software is now version 2.0.2.]

Using your 6400 as a print server for older local talk printers: Chris sent some info on how he setup his 6400 to run an older HP LaserJet and let other newer Macs without serial ports access it. Thanks Chris.

Thanks for the quick response. I got the problem solved. I eventually figured it out by trial and error. Your website has been very helpful over the years. I really appreciate all the time and effort you've given.

Here's passing along what could be of help from what I was doing:
I put a D-Link 530TX+ in a pci slot on the 6400. (Thanks to info on your site.) This put the 6400 on the ethernet network and using the local talk bridge control panel (downloadable from Apple TIL 60290) I was able to make my HP LaserJet 5MP (connected to 6400 via serial port) available to the whole network. I wanted to do this because I bought a new Mac (no serial ports) but didn't want to lose the use of the excellent output from the 5MP postscipt laser. This alone makes it worth keeping the 6400 around. (But it is still very useful in other ways too The 6400 is running 9.1 and using HP's print drivers. The printer is visible on the new Mac under 9.2 (HP's driver installed) and the best part - under Mac OS 10.2.2, the drivers are included, the printer is visible on the network due to the local talk bridge, and whole setup WORKS seamlessly!

This is huge in that for the price of the NIC ($10 at and downloading the local talk bridge, I don't have to run out and buy a new laser printer or serial adapter(which may or may not work under 10.2.2.

Thanks. Chris]

Confirmation that USB audio out devices do fix audio stuttering!: Kirschen and Scott both wrote to say that audio out from the iMic does not have stuttering problems like the stock audio out has. Thanks guys.

[Hi Thomas,
Just got my brand new iMic - plugged it into the third USB port of my OrangeMicro OrangeLink+ USB/Firewire combo board. Works fine with no stuttering at all! Floppy drive works fine. My current setup is:
Performa 6400/180 with 136MB RAM, Sonnet Crescendo L2 Cache G3 400MHz/1MB Cache. OrangeLink+ USB/Firewire. ATI Rage Orion (16MB VRAM). Farallon Comm Slot II 10/100 BaseT Ethernet. Mac OS 9.1

Thanks for posting that note from Luc.
-- Kirschen]

[The iMic works!! The CD Player app didn't work. I guess some of the older apps are "dumb" when it comes to digital audio. Quicktime movies play smoothly.
iTunes worked great, as did Quicktime. From what I can remember, I think the startup chime came from the machine but once the system was loaded all the sound came through the speakers.

Its possible that older apps like Apples CD Audio Player do not recognize the USB drivers for audio output? Also the CD Audio Player does not gets its input from a digital source. It actually gets its input from the audio cable off the back of the CDROM drive. iTunes however takes the data off the CDROM over the SCSI bus and then will either play it out your stock speakers or through a USB audio out device if you have one. So it seems we have a cure for those with some money to spend on a USB card and USB audio out devices :(

6500 G4 mother board mod!: Well, Adam took a 6500 to the extreme or downgraded a Gigabit G4 depending on how you look at it :) He sandwiched a G4 mother board inside a 6500 case. Check out the link below for all the details. Thanks Adam.

[Long story short, I made a G4 with a 6500/275 case... thought you might put the link on your site - I think it's pretty interesting

Sonic System ethernet card in a 6400: Alec sent me some info on an older ethernet card made by Sonic System. He says it works fine for him with at least OS 8.1. Thanks Alec. He sent me the driver incase anyone needs it so email me if you do :)

[Hi Tom,
Seeing you are recording ethernet card info, both of the 6400's here have Sonic Systems Inc PCI 10 cards in and they work without problems under OS 8.1. One card is 10BaseT only while the other has 10BaseT and 10Base2 connectors. A small driver extension 'PCI-10 Ethernet' is needed for the cards to function. One of them is an ex-college machine (they now use all PC's) and they ran without problems on the network there using System 7.5.3.

OSX on a UMAX C500: Terry was able to install OSX on a C500 by first installing it on a Beige G3 and then moving the HD over to his C500. This is one theory I thought might work for the 6400/6500 and its good to hear it can work. Thanks Terry.

[Hi Thomas:
I too have had trouble installing OS X from the boot CD. What I finally did was install OS X using a Beige G3 and then simply moving the drive to my C500. Of course I have a minimal install of 9.1 on a very small partition and the 1st and largest partition has X. I am using the latest version of Xpostfacto to boot into X.

We are talking X.2.2 here. I have an old ATI Mach64 video card and a Realtek8139 based ethernet card in my 2 PCI slots. I am even using an old 12" monochrome Macintosh display. My C500 has a ZIFF based CPU slot with a 280Mhz. Mactell G3 card with 1MB L2 cache in it. I also have the maximum 144MB ram (16MB on the motherboard) in it.

I will try something similar with a similarly outfitted Umax C600 tonight. The C500 has been stable since I put X in it a couple of days ago.

PC SCSI card in a Mac: Tinman wrote to say he was able to use a cheap PC card on the Mac and it works except for booting. Thanks Tinman. Thierry also adds that you can use the PC version of the Adaptec 2940UW and flash it to work on the Mac. Thanks Thierry.

[Thought I would let you know that I am able to use an I will SCSI card made for the PC containing the Advansys 3030 SCSI chip on my Mac. It is an Ultra or Fast card and although the BIOS is not flashable and any drive connected to it is not bootable, using the drivers on, I am able to use the card on OS 9 and X. I think any other SCSI card containing the Advansys 3030 or 3050 chip will probably work. This would provide cheap faster SCSI for the 5500, 6400, 6500 and other PCI Macs.]

you can also use an Adaptec 2940UW card from the PC side. It will work on the Mac if you flash it with the 4.1 flasher utility.

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 $10 US which includes shipping, 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 :) I will accept money orders and personal checks but I won't mail out the CD till it clears. I can now accept credit cards through PayPal as well!, books and more 7/2/98

I found a great way to earn some money while getting great deals to you on Macintosh books and software plus they have all kinds of other books, music, and more. Please click on the link on the top of this page whenever you feel like purchasing something to help sponsor this site. If you're unsure of what you want and wish to get a list of Mac related items, just type Macintosh in the search field on their home page and you will be presented with many choices to select.

TW Computing Business sites 11/2/2002

This page lists TW Computings Business Account holders web sites. I am placing them here on my site for two reasons. Many people visit The 6400 Zone and some of you may be interested in the products or services that these businesses deal in. Second, The 6400 Zone is visited by many web crawlers or robots that scan the internet looking for new sites. By placing links to sites hosted by TW Computing here, I can help them increase their chance of getting listed on most popular search engines. I figure that's the least I can do since I own TW Computing and it hosts The 6400 Zone :)

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 every other 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 and I will check it out.

I use a Performa 6400/Vimage G3/320 OS 9.2.2, two B&W G4/500's OS 10.2.2 Server, iBook Dual USB OS 9.2.2 / OSX 10.2.2, PM 6100 G3/240 OS 9.1, Dual G4 800 OS 9.2.2/OSX 10.2.2, and a PowerBook DUO 270c OS 7.5.5. If I encounter any problems, I will post them for all to read and respond to. Likewise, if you are having any problems and would like help just email me and if I can answer it I will, or I will post it here for others to read and respond to.

If any of the links do not work properly, please send an email to me the Site Master
