The flyback transformer (FBT), also called a 'line output transformer' (LOPT), is a special transformer which is used to generate high voltage (HV) signals at a relatively high fre…

That way the secondary PSU powers on at the same time as the SE/30 does -- all with the flip of the same switch you are accustomed to, on the back of the SE/30. Click to expand.…

I looked at a bunch of bad backlit portable mobos for Houlton, and all of them had problems with the 5V power regulator, as does my own 5126. Apparently the integrated voltage refe…

The 83 MHz bus is not entirely stable. Assuming a 400 MHz G3 chip is installed then the G3 chip is not overclocked, just the bus. Look up the jumper settings and downclock the bu…

heh my school was a 30 min drive at 55mph Click to expand... I had to wake up, then I was at school. ;D home school.

Sorry about the delay, I got distracted when I went to boot it up. I do not know what happened(and it happened while it was not in use for the past couple years) but now the fan ru…

Definitely keep the 5400 - its a black 5400, and they're very hard to come by these days, especially in good condition, with the matching black keyboard and mouse. You can pick up …

... I believe the black 5400 is an Australian only special, but what machine would you keep - and why? Click to expand... I have a soft spot for towers, but the 6500's case has…

I purchased that PSU from Jameco by the way. It wasn't anything special. I bought it specifically to drive my internal 7200rpm hard drive, lessening the load on the stock SE/30 P…

It is most certainly possible - 9 years ago I was running dual hard drives inside my LCII, if you can do it with an LCII you can definitely do it with an SE/30, or indeed any other…

The Flyback is not a direct "Apple Replacement Part". The only thing close, would be the entire analog board as a service part. Any old stock has probably been depleted or recycled…

My G3, which I use as 2nd machine: G3 233 DT, overclocked to 83MHz systembus and CPU@292MHz. Working extremely stable! 384MB Ram, 500GB Sata HD, ATI 7000 64MB.

The black 5400/300 as it is one of the Only black macs ever made. The Mac TV has all the fame but I have never seen info on this black mac.

Hi, I'm culling my Mac haul again - just wanting to keep smaller, more used Macs. Two of the biggest Macs which perform and sound about the same - a 6500/300 and Black Director's…

Right now I am just waiting for someone to pick up my new scanner from the PO. The old AGFA SnapScan Touch is starting to get a little long in the tooth. Also, it's software will n…

Its probably a good thing nothing like that is anywhere near me, or my house would have more obsolete Macs than it already does. I'd have a hard time stopping myself from picking …

433MHz (overclocked 350MHz B&W CPU) 448MB RAM 4GB 133x CF card DVD-ROM that I can not remember the speed of. 32MB Radeon 7000 2 port USB 1.1 10/100 ethernet Audio on…

No, but I will obviously give it a whirl. Knowing little-to-nothing about overclocking, my question is whether it is the bus or the processor that needs to be "underclocked" again.…

This is a Great Topic and I'm very glad to see you spin it off from the "OS 9 Bubble" thread for doing some REAL TECHNICAL ANALYSIS! That's what this place is all about, serendipit…

just look on kiji for a nother imac, just plop in the hard drive and done, no changing transformers, if you do somthing wrong you are DEAD I just got a g4 and that replaced my g3…

Have you tried down-clocking it back the original speed and seeing what happens?

Mine is a Desktop model. 333MHz overclocked to 350 192Mb of RAM at the moment I think 8Gb hard drive iXMicro Twin Turbo 128-3D video card PCI USB card Currently running 10.2…

Been there, done that. I got a huge box of Wallstreet parts (and I do mean nothing but misc parts) over a year ago and built 5 units out of them (plus some ebay parts).

One thing I can report is that I once installed a logic board from broken up a 266MHz Wallstreet II into a nice little 12" machine (more vram & better graphics chip). I d…
