techknight, I've just checked the file using Chrome, Internet Explorer and Safari and it works fine on my side of things. Keep me updated if it does not work!

bigmessowires, Since I have been unable get my Macintosh 128k working I haven't been able to fully test its floppy drive. With regards to the drive head and stepper motor; they can be serviced with alcohol and white lithium grease respectively.

Hello all, In response to a fellow member's question about relubricating those full height Sony 400/800k floppy disk drives from early Macintoshes, I created a PDF guide which deals with the removal of the 'disk carriage assembly' so it can be ready for some deep cleaning and relubrication...

bigmessowires, I have created this PDF instruction guide to help collectors re-lubricate their 400k (and possibly 800k) drives. https://drive.google.com/file/d/0B6j6P7lBWw-BNHQ4dXRYZkFGdzQ/edit?usp=sharing I hope this helps!

uniserver, I have replaced all of the eight caps you recommended the replacement of. Unfortunately this did not solve the problem! I've uploaded some analog and logic board photographs: I've noticed on CP38, a RIFA component, that its case has a crack on its top. I hope this helps!

bigmessowires, I recently re lubricated the 400k floppy drive of my Macintosh 128k. The instructions provided are for newer, half height SuperDrives and 800k drives. The servicing involved removing four screws from the underside of the drive. This enables you to release the disk carriage...

Hello all, In September last year I bought a faulty Macintosh Classic II (40Mb HD, 4Mb RAM) with the intent of restoring it. To restore it to its former glory I recapped the motherboard and treated its case with Retrobright. I reassembled the Macintosh and turned it on to be confronted with a...

Hello all, Yesterday I replaced the four 100uf 200v filter capacitors with 100uf 400v 'High Voltage' ones. I was not sure if these would be suitable replacements but I replaced them anyway! But I still get nothing when I turn the Macintosh on! The second time I turned it on the switch tripped...

Hello all, I've replaced CR20 and CR21 but the same problem still remains; no activity from the Macintosh. On the upside, I can hear a quiet electronic buzz coming from the Macintosh. After the repair I measured the voltages from the floppy port: +5v = 0.68 +12v =0.05 -12v =1.75 I think...

Hello all, Hear Hear IIfx! The only 2.5'' SCSI hard drive I had that actually worked was an IBM 120Mb drive from a PowerBook 180c. The Conner and Quantum drives only lasted a few minutes, if they worked at all! Sometime the 'freezer trick' worked but it never seemed to last. I've read some...

Hello all, I have ordered replacement components for CR20 and CR21. The parts are the ones recommended by Larry Pina in 'The Dead Mac Scrolls'. I should have them replaced by the middle of next week. I will report back with the results! I don't know where you're based but there is no such...

Hello all, At the moment I am using a copy of Larry Pina's 'The Dead Mac Scrolls'. It has a large section about early Macs (128k, 512k and Plus). The problem I am having starts a page 21: 'The Mac does absolutely nothing. There is no startup bong. There are no unusual noises. The display is...

haemoglobin, I own a PowerBook G4 1.67 (max RAM, stock HD) and I can tell you that even seven years on it is still a very capable machine! Web browsing is a pleasure with most sites. Some of the more Flash heavy sites bog the machine down, but for the most part it just makes scrolling choppy...

Hello bigmessowires, I have just tested voltage of the 5.00v line on the analog board connector and the reading was 0.30v. It sometimes fluctuated but stayed steady on 0.30v. I hope this helps!

When I tested the voltages on the floppy port they all read under 1.0v (more like 0.50v). I will try measuring the voltages directly from the analog board later today them report back! Thank you

Hello all, I have been looking at my copy of 'The Dead Mac Scrolls' and I think the problem could be centred around the following board references: CR5, CR21 and CR20. The leads of CR20 and CR21 look like they have been blackened by something. The component in front of CR5 looks like it has...

Hello all, I am busy restoring a 1984 Macintosh (240v International) but have run into some problems. I have already posted about my experiences trying to find replacement components and recapping most of the analog board. Here is the topic in question as it will serve as background context...

Good evening, I think the problems I am currently facing outgrow the purpose of this topic. Therefore I will start a new topic to discuss these new problems. Thank you to anybody who helped me source replacement components! If anybody else needs a component identified feel free to 'hijack'...

Good evening, I have replaced most of the capacitors on the analog board; these include: R uf V C1 3.9 25 with 3.9uf 250v axial C2 4700 16 C3 220 16 C24 2200 16 C27 2200 10 C28 1000 16 C30 2200 10 C31 220 16 C32 2200 16 C45 470 10 C42 470 10 I have not replaced C11...

The replacement capacitors and 2SC3260 arrived today and have been soldered onto the analog board. I'm still not sure about the four 100uf 200v capacitors but I will leave them in for the meantime. Capacitors have replaced with ones of the same value but the sizes have shrunk dramatically! I...
