    Full 68040 for Quadra 605

    Love the subject here. My only concern is Overheating and how to deal with it. the LC case does not give enough space for a good properly sized heat sink to be put into place, and the LC Fan is something least to be desired.

    Incorrect time on Mac Mini G4

    Hope I'm not too late on this, but you can use a painter's spatula to shoe between the case and the base and lift the case up bit by bit as you work the blade around. It is not that hard! It is one of the easiest systems I got into once I figured out how. Review the video I posted above to see how it is done.
  3. Even if you go cheap by using a CF as an SSD on a G3/G4 iBook/PowerBook, you're talking about Boot times of under 30-45 seconds compared to a hard drive that can take up to 5 minutes, depending on extensions and OS size.

    Incorrect time on Mac Mini G4

    The G4 Mac Mini uses a simple button/coin type battery as used on PCs. I forget the size but it is in a socket. Push on one end of the socket and the battery pops out. Put a new battery in by pushing into the socket. Should be no more than $4 to replace it and about 15 minutes to replace it. While you are in there, you might as well upgrade the RAM and HD if you can. ALSO - be careful with the antennas wires. There are many You Tube Videos, I recommend this one: NOTE: At 3:20 on the video, you can see the battery in a socket by the first on the right next to the plastic case hook. Even though the battery is a coin/button type, the battery holder is a vertical type. Go figure!

    IIsi works, then doesn't

    The LC475 PSU is easier to fix/recap than the IIsi. But it sounds like you need to recap the motherboards as well on both. You just need to get the information to do the information. IIsi PSU info: http://maccaps.com/MacCaps/Capacitor_Reference/Entries/1990/10/5_Macintosh_IIsi_Sony_Power_Supply.html LC475 PSU if it is an Aztec unit: http://maccaps.com/MacCaps/Capacitor_Reference/Entries/1990/10/15_LC_I%2C_II%2C_III_Power_Supplies.html You would need to scour the web for THAT other LC PSU used on the LCIII and LC475 After you recap the PSUs, you should start on recapping the Logic boards.

    Mac IIci PSU recap advice

    There are two tiny caps on the IIsi PSU Daughter Board that causes 90% of all PSU problems on the IIsi. Replace them and the IIsi comes back to life... most of the time. As an added insurance, one can recap the rest of the PSU. I remember this from a former member who was here and sold caps and repair services. Here is his old website about the IIsi information (and the two caps involved). Hope it dos not get me into trouble... http://maccaps.com/MacCaps/Capacitor_Reference/Entries/1990/10/5_Macintosh_IIsi_Sony_Power_Supply.html

    My IIci rebuild video series

    I find that once you recap the board, the PSU works fine on most cases. There a are a couple of large caps inside the PSU you could recap if you like.

    Plus with Horizontal Sweep Lines?

    I have the actual DMS from the mid 90s.

    3D Printing old PowerBook parts?

    I too have a 3D Printer, 2 actually. Only one of them would be big enough for such a project. The problem is warping due to uneven cooling when printing. This is a major problem for parts that long and wide and ABS plastic
  10. Using a CF (or any SSD) on a G3/G4, I find best to edit the system preferences to shut off event & crash logging as they tend to fill up a hard drive quick. It has been a very long time since I did this so I forgot which preferences to shut off but it is somewhere on the internet. Personally, I have not had issues with my CF Powered G3/G4s. They are quick to boot and load up apps. I did have an issue with a Crucial M4 SSD with total Data Loss after 3 weeks and they refused to honor their warantee citing User Abuse as the cause for the Data loss, so I am not happy with them, not one bit! I have had good luck with a Cheapo Chinese KingSpec SSD. The PATA II they have is wickedly fast, and the 2.5in drive they have is cheaper than the 3.5in - go figure! They both use the same size connector! Their PATA (or PATA I) tends to be slow, about equal to a spinning platter, but reliable. Since I did this so long ago, their (KingSpec's) 10 year warentee should be ending soon. So I wonder, when the warentee dies, will they go thermal nuclear or do I have nothing to fear? I'm just joking, I'm sure they will be just fine for many more years to come. Same with the CFs I used - SanDisk and Trascend (sic.) Media mostly. But I should start looking into making backups for these systems soon.

    Se/30 have to bang the box to get a screen

    Cracked solder joints at the cable connections (Yoke/CRT and Analog to Motherboard connectors), and certain areas about the high voltage circuit like the cap and flyback transformer. But do not just add solder or reheat the joint. You need to remove the old solder, clean up the board and circuit part with some IPA, and then solder with fresh solder off a spool.

    Best macOS version for IIci?

    It depends heavily on how much RAM you have in the system. Under 16MB, System 6.08 or 6.09. Greater than 16MB, System 7.1. System 7.5 - 7.6.1 I find laggy on the IIci, even after using a PowerPC/Fat checker to remove what PPC might be floating about the OS.

    My First Recap - LC

    A lot of times with these old systems (Macs, PC, even VCRs and TV; and one time I seen it on a washing machine!), Bad caps on the logic/mother board can keep a system from turning on. this would make you think that the PSU is bad when it is not the case. But with these little LC PSUs, it's a must to recap it. But if you recapped the board, chances are the PSU will be able to turn on the system even with bad caps in it. Even though it does, does not mean that the caps in the PSU shouldn't be changed, they should. Ha! In thinking about the washing machine, I have to wonder. It was built in 1990-something, and it refused to turn on. My friend (who fixes ACs, Washing machines and other appliances) was stumped by this one. He swapped out the controller board, the motor, switch sensors, electric valves, everything but it would not turn on. Then I saw this large filter cap in the side of the machine's innards and told him, "See this? Change it." He did after searching most of the day for another one, and the freaking machine turned on! Then I told him to put back the original parts and he did, to his surprised nothing was wrong with the original parts! After that night I was helping him through Newark and Mouser website, where he found the filter caps on one of them (Mouser I think) and he bought 10 of them for around $50. And since then, the first thing he tests/replace is the filter cap. Ha!

    My First Recap - LC

    I tend to over voltage my caps, if it says 25V, I'll put in a 30V or 35V cap but nothing more than 15% over. When I did the PSU on my LCs, even if I were stuck with same voltage caps, they were too big in size. But looking over the list on the website after my orders and receiving the caps, some (a lot but not all) caps has their physical measurements on them. I should have measured the caps to order the correct size but I did not. So if you can give the extra time, measure the physical size of the Cap on top of the uf and V of the Cap. then see what is there and order what you need.
  15. I use a CF Card (16GB or bigger) with a CF Adapter on my Wallstreet and other PPC/G3/G4 powerbooks and iBooks. You will need a Single CF to IDE Adapter, the Double CF one will not work, and of course the CF. You will need to do some surgery to the adapter by removing one of the pins, (I think Pin 22, check with the back of the hard drove and see what pin is missing and remove it from the adapter). You can also use CF to PCMCIA adapter and set up and boot it from the PCMCIA Slot. The How to link her is dead, don't know why....
