    SE/30 motherboard problem ??

    Thanks to Ike for the lead to the SE/30 repair page. The screen was the "Irregular Vertical Rasters" as shown on the the web site. After seeing the damage on the mother board I am amazed that it was able to do anything at all !! I will try some type of cleaner to dissolve some of the corrosion that is under and inside the rom chip mount. The rom chip itself needs a good cleaning too.

    SE/30 motherboard problem ??

    Here are a few more pictures. I will do a more thorough clean up with the swabs and some alcohol soon. The area under the chip mount has some serious corrosion. I did not think that the pram battery would be so corrosive over so much area !!
  3. I picked up a very nice SE/30, outside condition very clean. I booted it up and got a garbled screen. The hard drive was running, but very noisy. I have an external drive that I wanted to use to replace the internal drive with. I popped off the case and was surprised by the mass of brown corrosion surrounding the pram battery!! The mounts for the battery were eaten away and some of the surface mounted components nearby were eaten by the corrosion. The edge of the video chip was also badly corroded. Sort of put a hold on my project. The unit was assembled in Ireland in May of 1991. I kind of think the motherboard is finished ? I have an SE motherboard that I will try and use, it should work. I am thinking that any SE/30 motherboard will work? Any comments ?

    Just picked up (another) HD20

    I hope this one will work out for you ! I used to pick up external drives from our Value Village store. I picked up a HD20 and a HD40 @$7.99 each. I bought a TopDrive for the same price. I swapped in a 350mb drive into that one and it sits under my Mac Plus with O.S.7.0.1* on it. It really depends on where you are, when it comes picking up old Mac stuff. The external drives are a nice way to go and they lift the monitor up a bit and can resolve some heat issues.
  5. A good cleaning will do wonders for the old floppy drive. I did the swap you are working on a few years ago. I swapped in a 1.44 drive out of a dead Classic. Between the dust build up and old grease the drive barely functioned. I swabbed and blew out lots of gunk using compressed air and alcohol with Qtips. Then I oiled the mechanism with G96. A product I had always used to clean and lube firearms. The drive functioned smartly with none of the drag and whining that it did before the clean up. The drive has worked perfect since the cleanup, about 3 years ago.

    SE/30 cpu swap ?

    I am going to leave the SE/30 cpu alone till I can pick up a real accellerator card. The SE/30 has 20mb of ram , a 1gb harddrive and is running O.S.7.0.1.* I am slowly loading it with vintage games and interesting apps. Thanks to all those who posted .

    Cheap emate battery fix.

    I was trying to get my emate charged up with no luck. The batteries were totally dead. No real surprize as they are the originals from 1997. Earlier in the year I had bought a damaged rc (radio control) car for $2.00 at a garage sale. It had a 9.6V battery pack in it. 8 rechargable batteries!! I split then into two groups of four. Cut some tape, nipped through one of the metal tabs. They are soldered together just like the emate batteries 4-pack. I unsoldered the emate connector and resoldered the two wires to the top of the recycled battery pack. Being carefull to solder them the same way as on the original. All the sticky paper insulators from the emate were used and fit fine. The sensor unit fit in the same place on the batteries too. Put everything back in place and plugged it in. The charging light came on. It is amber, then about 1/2 hour later it turned to green !! Unplugged it from the charger and it booted up showing a full charged battery. I had it running for three hours. Turned it off overnight and booted it up this morning. Still showing full charge. It was a cheap handy fix. The batteries are a decade newer and I should get years of use out of them ! I also bought a small solar panel at another garage sale, maby I can find an adapter and.........

    Good buddy, good junk = good conquest

    I have been tinkering with both my units. The PDQ is now running O.S.9.2 . I upped the ram from 128mb to 256mb. Feels faster and smoother. I downloaded Classilla ! The emate had a quick change of batteries as the originals were dead. The cell swap went well and everything fit back in. The hinges need to be fixed asap. Looks like I will scrap trying to use the irda ports. I will check for a serial cable in a day or so when I get back to the city. I want to use the emate on the road and sync. to the powerbook when home.

    Good buddy, good junk = good conquest

    The emates and the PDQ powerbook are both good finds. Having them working together is great ! I am working at getting my PDQ to see my Emate. No luck so far. I was hoping to use the ira ports to transfer files. How does your setup sync. ? My PDQ is running O.S.9.0.4.

    SE/30 cpu swap ?

    Another thought on this swap. The 030 cpu is a more modern model. If I read the specs right it has a 256k cache on it. I was thinking that even if it only ran at 16mhz, there might be benefits because of its more modern design?? The cpu I am thinking about is a "MC68EC030RPC40C" . It said something about being used in embedded applications ? Might this cpu be used in an accelerator as they also have a removable cpu? Any thoughts on this ?

    SE/30 cpu swap ?

    I am thinking about trying a cpu swap on the SE/30. There is a 40mhz 68030 cpu available. I am pretty sure I have a SE/30 motherboard with the socket style cpu. I think it would work, but the new cpu would only run at 16mhz. Without having the expensive accelerator, is there anyway to make it run at 40mhz ?? I would have to purchase the cpu, so it would be nice to know if there is a way to make it work. Any suggestions ?

    Five Ibooks !

    My boys will get these two. It is a big step forward from the CF-27 Toughbook they usually share. I will try some of the motherboard fixes and see if I can get one of the other ones going for myself!

    Five Ibooks !

    The 1.33ghz ibook is a bit more challenging!! I figured out that the video problem is due to a bad cable. The no start problem was actually a dead hardrive. I swapped in a good one and everything started up as it should. But it also has a faulty dvd-rom drive. So it looks like the third G4 ibook will turn into a donor for its LCD cable and dvd-rom drive. Those parts will not swap from the G3 ibooks. Lots of great fixes for the ibooks on the net. I thought the one brought up on an ealier post was great!! Flames on the motherboard

    Five Ibooks !

    I did a bit of research on the web about swapping LCD's and got busy. It took me an hour to disassemble the two ibooks, swap in the good LCD, close everything up and test. I think I can do a swap in thirty minutes now that I got through it the first time. The now working G4 ibook has 1.07 cpu, 1.25gb of ram, 30gb hardrive. The donor G3/500 had some good parts besides the LCD. It was upgraded somewhere along the line. I got a 70gb hardrive, dvd-rom drive, 256mb ram strip, airport card and a good battery to add to my parts supply! The G4 1.33 is next in line.

    Five Ibooks !

    I just picked up these ibooks as parts from a local seller. All have issues. Three G4 Ibooks and two G3 Ibooks. No video at all on the 1.33ghz Ibook, it bongs on start up. Damaged screen(1/2 of it works) on the 1ghz G4, boots and runs fine. The third G4 is a 1.2ghz model, it bongs on start up and the screen lights up with nothing on it? The last two are G3's (500mhz & 600mhz) Both have video problems. If you squeeze them the video will stay on. I really want to get the G4's working if possible. Since the G3's have the video chip problem, I am hoping to swap their screens onto the G4's. I am going to start on the 1ghz Ibook as I know everything works on it. The screen is physically damaged, but the video is working fine. It would be nice to get two good working G4's out of this pile! Any thoughts on the G4 that lights up but does nothing??
