    Interest in adapting 744x to 7400?

    I will soon have a G3 B&W tower and I have an extra G3 233MHz ZIF CPU. If you want we can try updating to 7447, I have a 1.25GHz taken from a Mini. As the B&W supports bus overclocking to 133MHz, with the X8 multiplier it could reach 1067MHz, I don't know if the interposer allows PLL4 to be...

    Interest in adapting 744x to 7400?

    I looked at these two photos and I have two questions. Are the additional interposer capacitors optional? in the dual they are not placed. My other question is that the 7400/7410 have PLL0-3 but the 7447 has PLL0-4, where do you adjust the additional PLL4 when you use interposer? I only see...

    HD SCSI for PowerMac 7600

    Thank you! I'm going to try it and tell you! P.S. Is it possible that on the 7600 the termination is in the CDROM unit?

    HD SCSI for PowerMac 7600

    Hello, today I received the adapter. I have start with BlueSCSI 7.6 Install CD Image. Well, it seems that it doesn't work, it recognizes the bus and the ID, but it gives me this message. Is it because of the termination? What is "force single ended" option in the hard drive? it makes the same...

    PowerPC 7457 upgrade for iMac G4

    Hello! @re4mat I just discovered this post! It's been many years, but I recently did the CPU SWAP to an iMac G4 800MHz, and I would like to add the L3 cache. How did the project progress? I have not made any modifications to either the power supply or the Vcore regulator, except adding a LowESR...

    iMac G4 800 CPU SWAP

    Hello, I've been playing with an iMac G4 800MHz GeForce2 for a few days, and I've been writing for a few hours now, so I'm not going to go into much detail. In my blog I have reported my SWAP on an iMac G4 800 that works stable at 1.3GHz...

    Lombard with G4 upgrade

    Hi, try getting a Sawtooth/Gigabite G4 CPU card, and you can use its cache chips to replace the ones in your Lombard. I don't think you'll find the new chips these days. Any IC replacement service can do it for you.

    550MHz G4 PowerBook (Pismo vs Titanium)

    Phew! You have done a great job of analysis. I'm afraid that it wouldn't work on the Lombard, for starters, the northbridge it has is different from the one on the Pismo (I have one of each CPU and I can compare) So, with the changes you've made, what would it take to be able to test a 7447/8...

    550MHz G4 PowerBook (Pismo vs Titanium)

    Brilliant!!! and how did you change from 60x to MPX? Should it be done in the firmware or in the software? Would this be possible in a Lombard? Because there was no update to G4 for Lombard that I remember.

    HD SCSI for PowerMac 7600

    Okay, thank you very much. When I have the material I will carry out tests and tell you my results, although I am afraid I will have to buy the MAX adapter... Do you have photos of this adapter? :)

    HD SCSI for PowerMac 7600

    Okay, I'll contact him if plan A doesn't work. I tell you news. I attach HD photos that I bought. If you look at the label, it includes the text LVD/SE. So this HD will allow me to terminate the SCSI chain? Should it have a jumper to activate it or is it already activated by default? I will...

    HD SCSI for PowerMac 7600

    Thanks for your answer!!! Does MAX have an online store or does it sell here on the forum? How is termination indicated on a SCSI bus? Does the device do it or is it applied to the cable? I bought the adapter from Aliexpress but it will take a few weeks to arrive. I would like to see and try...
