Tonight's project was to get the CC playing nice over Ethernet, which then turned into installing  and setting up MacTCP and finally after some degree of fiddling and tweaking setting, culminated in this... I am a little excited by the fact I have a 16Mhz Mac connected directly to high speed...

Tonights job...

As a general rule of thumb, any 601-based PowerMac I use OS8, 8.5/8.6 on 603-based machines and 9.1 on 604-machines... that being said I am running 9.2 on my 9600 with OS9helper. G3's and G4's from the graphite era, OS9.1/9.2 and OS 10.3 are where it is at... 10.3 actually runs faster than 10.2...

Yeh I'm quite enjoying using it actually... posting this from it in fact. I still havent worked out exactly what it's affliction to the R7k or the properly working Rage128 is yet, but it is functioning fine witha TT in it so that suits me fine. I ended up tossing in the G3/400-1Mb Sonnet card...

Sounds like all systems are go then. :) Might do the switcheroo then. Would I be right in assuming the majority of programs wouldn't really be able to make use of the multiprocessing functionality of the stock processors and as such I would pretty much be basically no better off than running a...

Mmmmm at this point in time, a machine has to be fairly special to warrant me bothering with a flyback replacement. If one were to fail on either of my iMacs for instance, I dare say at this stage I would simply just replace the whole A-board with a known good unit. If I had something rareish...

I recall reading somewhere... fairly recently even, that there was a certain CPU upgrade available for the 9xxx/8xxx/7xxx series PowerMac's that had an apparant link to failures of the onboard  SCSI controllers on 9600 logic boards when installed, inasmuch as machines fitted with said specific...

And we have one more clean, perfectly functional Color Classic back in the world again after a solid night's work... This is the same machine that looked like it was pulled from a septic tank just yesterday. :)  I ended up putting the better board out of the other machine into this...

Yep definitely seems like it's not doing it's thang... from memory I can't ever recall hearing the degaussing "thunk" when powering this CC on, yet all my 5xx-series and the other CC do it, and all are free of screen anomolies. Where would I be looking for the componentry of which you speak...

Hmmm possibly... I do note that the second one with the shadow doesnt make the same "thud" when the hard power switch is flicked on like the other one and just about every other AIO type Mac seems too when hard power is turned on. Anyway, I'm going to set about cleaning these two animals up and...

Tonight is just getting better! :D Stiff brush across all the IC legs and CC #2 which I got from the original owner around 12 years ago now boots up again complete with a healthy chime. Definitely seems to have evidence of caps gone leakies in the past however so this one will be going at...

Had a small success just now in that I got one of my pair of non-functioning CC's to power on. After giving the various  I/C pins a clean up on the IIvx board got that machine booting and running flawlesslyagain the other day, I decided to give the less pretty of the two CC's the same treatment...

The SW, SWII, and SW1200 used the BC-02 Black cartridge, And the CSW1500 used BC-02 Black and BC-05 Colour cartridges which are a Canon BubbleJet item (for obvious reason), this much I do know. I beleive the cartridges in the CSW 2400 and 2500 are BCI21B/C and some higher capacity ones i think...

From my experience the PowerMac 5500's had flyback issues also... basically it was just a matter of whether the logic board would last long enough for the flyback to fail. lol. So it's quite likely the G3 AIO can suffer similar issues.

Update... I put in the RAM module from my other classic with the AB needing attntion and a pretty sad looking logic board, then went went to boot up again, only to get a garbled checkerboard pattern the same as I got on that Mac but without the vertical oscillations. Unfortunately I got yet...

Well, looks like it was a simple fix. Pulled out the entire RAM expansion module as a unit, pulled the board for a quick visual (no leaking caps), and put it together just leaving the onboard memory and both drives unplugged... it bonged and booted to a flashing floppy icon as normal. Going to...

Mmmm I was going to do a precautionary recap soon on the machine anyway even though the machine worked perfectly and seemed in good shape. I will pull the RAM for a start and see if it helps and maybe pull the ROM as well and reseat it and go from there. :)

So, It would appear the first line indicates initial memory test fail, however I am not so sure how to decode the second line exactly... Also, I not on a 4th bootup attempt, where I get the garbled artefacts again, I actually get a slightly different error to the clean screen error. whilst I...

So I just went to boot up my Classic and got the following sad mac error... 00000002 0000FFF7 The first boot produced a bong, then the sad mac appeared, 2nd attempted boot I got no bong and went straight to the sad mac with some video artefacts. 3rd attempt I got no bong, still got the code ...

Yep, unlikely you will find a brand new replacement part... best bet is to find a stuffed 1400 on the cheap with a good LCD and scavenge parts.
