Hi, I bought a beige Power Mac G3 mini tower. It has a G4 400 Mhz processor installed instead of the original G3. The replacement is from a company called Metabox (went out of business long ago). I read it is basically the same as Sonnet's Encore/ZIF G4 or Daystar's XLR8 MACh Speed G4 ZIF...

Today the drive (mechanism) died. The platters spin up and then the drive makes 4 repeating sounds as if the heads are stuck and it tries to make them move. After nearly 30 years that's ok I guess. RIP.

Hi, I just acquired a 40SC in its original state from end of 80s. I thought this might be useful as a reference. Luckily the Service Source for this hard drive family (20SC, 40SC, 80SC, or 160SC) is still available: http://tim.id.au/laptops/apple/misc/external_hard_drive_sc.pdf so it is easy...

Sorry, I do not get it. I have US Mac Plus, why would it have an international analog board?

I guess I'm very lucky. The mainboard of my new Plus looks phenomenal. Just a bit of dust. It has 4 MB installed. The caps on the mainboard are of normal axial type: 5x 33uF, 16 V 1x 1uF, 50 V All are ca. 13 mm long (just the body) and their solder joints are ca. 20 mm apart. The caps look...

Ok, thanks. I still would like to have a complete list of all caps (analogue and digital board) for reference. So far I found one for the analogue board: http://www.jagshouse.com/68kfaq.html#plusanalogue

Is there a list of capacitors for replacement available? I searched here and in the web but did not find one. TIA, bobo68

Sorry for the topic, could not resist.  :) I just acquired a US Macintosh Plus in nice (outside) condition. It is a 1987 model. It even came with a voltage transformer as it was used before over here. I guess I have to do the usual recap. Also the screen flickers when I (gently) hit the...

Try "Glider".

Try a diary.  :beige:

You should be able to format in PC/IBM/DOS format on the SE/30 instead of Apple's HFS (depends on the System you use). Likewise you should be able to read and write PC formatted floppies on the Mac. Does it work that way?

I have to second that. Bought quite a few 80 or 68 pin SCSI drives lately and they all do not work reliably (if at all) with different 68k Macs. Would not have believed this but sadly it is true. 50 pin drives usually work but they are older and their hardware fails after all these years.

I just got a RasterOps ColorBoard 708+. Does anybody have drivers for this card? TIA bobo68

No, sorry. I'm not an expert on this and I never really thought about ceramic caps. I first wanted to replace the electrolytic caps with new electrolytic ones but then went for tantalums because the electrolyte obviously can do huge damage. Tantalum works for me in the Macs (I heard that there...

Hi, just finished recapping my IIci with tantalums. Works nicely. You can see it getting a fresh System 7.5.5.  :ii: The machine came with a rare video card I guess. It is a Miro Prisma Plus V 1.1.d made in W. Germany (1989) :) There where no drivers for the video card on the hard...

Oh man, that looks horrible. I wonder if replacing Y1 will help... Anyway, Y1 is an oscillator (piezoelectrical crystal) with a frequency of 32.768 kHz. Normally it looks like this:

Ok, didn't know that not U*I but just I is important for the fuse to break the circuit. Had to replace it with a bigger type (20 mm x 5 mm) with holder caps though but now it works.

Of course you were right. The fuse is a 230 2AG type, rated *250 V*, 0.5 A. Seems weird to me because it sits between the 12V feed from the Asante Maccon PDS card and pin 13 of the AUI connector (voltage plus). Would a fuse of these dimension even give protection in this case?

Yes, that can be the case. There seems to be a rim between the outer caps and the fuse itself. I'll fire up the soldering iron and have a look.
