Someday I will also build the fastest OS 9.x native booting machine (most likely a single processor system). I have yet to bother since high end G4's still cost a few dollars and I…

There are a small handful of programs for OS 8.6 > 9.2.2 that make use of the second processor. Back in those days, apps had to make specific use of the second processor. If…

Alright, thanks!

Whatever board you're putting into the 5500, you'll need the 5500 cover.

BTW, can I use my old 5500 plastic cover, or do I need to track down a 6xxx series plastic cover?

None of the Prozessor Upgrades is listed(!) to work with a G4 with 167MHz System Bus speed. Not Powerlogix, not Sonnettech, not FastMac, Not Newertech, Not OWC, not GigaDesigns wil…

I was going to post my HD sounds but my digital recorder only records in .msv format which is not compatible with macs. Anyway, I would like to know if it is possible to get my PB…

The reason I asked that is because when I would boot from my HD with a full install I could sometimes recognize and charge the battery. When on a floppy running the 3 battery reco…

I am not sure. Some of the battery software is certainly loaded from the full system (e.g., there is a Control Strip module), and so you are not going to get all the bells and whis…

Is it possible to charge and use the battery without a regular install? Like if a boot from a floppy?

Knowing (cr)Apple they're probably still bound to an NDA and can't say anything. I know these machines are 22 years old, but still....Apple is Apple, and we all know what they're l…

However, Larry Pina's Macintosh Classic and SE Repair and Upgrade Secrets specifically refers to the "heat sink screw" at the front of the PSU and makes specific mention of heat si…

why you want an os 9 only machine is beyond me Click to expand... Simply because I don´t like OS X, and will never use it. And because I think that OS 9 is one of the most logi…

YES! *does a backflip* Thanks so much! Are you sure it'll be compatible with the extra PCI slot and all? Click to expand... Well no...You'd have to swap the PCI risers. The 55…

a number of the OS 9 bootable MDDs have 167mhz bus speeds and DDR RAM and ATA 100. Having a faster processor on a slow bus is limiting. Click to expand... None of the Prozesso…

why you want an os 9 only machine is beyond me but the last os 9 capabel machien apple offerd was the 2003 reintroduction of the 1,25 dual G4 MDD

I doubt very much that a single thin piece of metal can absorb and dissipate heat in any meaningful way to actually maintain or reduce temperatures. Larry Pina's Macintosh Repair &…

YES! *does a backflip* Thanks so much! Are you sure it'll be compatible with the extra PCI slot and all?

Yes. The 54xx/55xx boards and their 6xxxx counterparts are interchangeable.

My 5500/250's motherboard seems to be acting up. Thanks! -JRL

Even with the Mac 128K Apple was installing heat sinks to help pull heat away from the delicate electronics and radiate it into the case where convective air would then exhaust it.…

I've never heard that any particular, fairly modern, OS can't utilize dual/multiple processors. NEVER believe (without checking multiple reliable sources) what you've "read at diff…

Sonnet lists an upgrade for the Mirrored Drive Door. Click to expand... Yes, but the 2nd processor can´t be used by OS 9. That´s what I read at different places. It will fit, i…
