  1. I'm wondering if it might be down to your Mac's past life... there are actually two lengths of case screws: I've found in the less adulterated (perhaps Plus and later?) ones I've worked on that the 'shorter' ones are used for the CRT and for attaching the internal frame to the case front. YMMV...
  2. In that original doc I was referring to, lower down it stated: So my guess is any (68k?) Mac that'll run AppleCat/MacTest (and has a modem port) should work... Obviously the Color Classic wasn't out at that time... I'll see if I can at least give MacTest a spin today...
  3. I've had a few things get in the way... but hoping to have a go at bringing my Portable back to life in the coming week... I've downloaded the various MacTest options from the link above, but the document refers to a special 'combined' version... AppleCat/MacTest Portable. I'll have a trawl through the files from MacintoshGarden... but has anyone listening heard of this unicorn?
  4. Nice! Not sure when I'll be able to get to my Portables... maybe this w/e ... Will report back once I've had a spin. I did note in the description... "MacTest Pro is a subscription diagnostic product..." - hope it won't be a false start!
  5. I've been following this... but now I'm even more interested. I've just brought an SE back to life - complete with '030 accelerator courtesy of @Bolle - and working their way to the top of my repair queue are a couple of Portables. One I know was working fine - but had a dead vertical row of pixels - when I shelved it a few years ago... and another I acquired recently which would not boot... "Sad Mac" It'd be great if someone has that magic diskette tucked away somewhere...
  6. So stick with 90C? ... just bake longer? Um... can you explain?
  7. Sounds like you've been there before.... Update on mine... baking Round 2 was 4 hours @ 100C.... I bumped the temp slightly since 100C is the boiling point for water (212F)... Initial results were even better than Round 1... here we are right after full boot... Unfotunately, after ~2 minutes... the darkening started... ...and after ~11 minutes... it was starting to really show... I still consider this a positive result... before any baking, the screen started to darken almost immediately, a
  8. Have you checked out this thread? I'm currently 'baking' mine a second time... noticeable improvement first time 'round... so we'll see...
  9. Just chiming in... Glad I found this thread!... I recently purchased a faulty (screen issues) PB180, figuring it probably needed a re-cap (which I've done on my PB100 with success... Oh no... it had a serious case of tunnelling... Just like @GregorHouse mentioned originally "Corners begin to dark after a few seconds and in a two minutes nearly all of the screen is dark." I was about to go on the hunt for a new display... when I found this thread and realised I was not alone. So... I stripped the display, pulled the panel and baked it yesterday for ~4 hours @ 90C (I'm in the UK)... The r
  10. Resurrecting this old thread in the hope of some advice / guidance from the pros... I have a Mac Plus which decided to go "pop" recently when I powered it up. Inspecting the 'board shows a blown fuse and a disintegrated Q12... ...further inspection, also seems to indicate that the insulation on the flyback transformer is gone... This happened a couple of months back... and I vaguely recall finds bits of 'something' - which may have been the fragmented insulation... A visual inspection of the 'board doesn't show anything else amiss... it's actually
  11. Although not directly related... I have a Plus which a couple of months back went snap/pop = dead. Inspecting the [International] AB showed that Q12 had disintegrated... I'm researching now and found another thread here discussing Q12 - Thought it might help if you've not run across it... Did you get yours back up and running?
  12. Just to close the loop... Thanks to @Damian Ward for letting me test out one of my 400k drives on his (working) 512k, I can confirm that the drive is recognised and reads a MFS diskette just fine. I also tried the drive on a Classic II (which I'd re-capped for him), but it behaved just like it did on my II and IIx. This seems to point to that requirement for a... A big thanks to everyone for sharing your experience! Now that I know I have a working drive, I can work on getting my 512k up and running!
  13. Thanks all! ... I'm working on bringing the 512k (as well as my Plus, which recently expired!) back to life. Once I have one working, I'll revisit these drives to see if I can get them working. Appreciate all the valuable info! FYI... there seems to be some debate here... according to the wiki [https://en.wikipedia.org/wiki/Integrated_Woz_Machine], SWIM stood for the Sander-Wozniak Integrated Machine ... Personally, I like 'Super-' better...
