Re: [vcf-midatlantic] MAC with squashed screen (william degnan)
I am thinking about working to repair the display on my '84 MAC, occasionally the horizontal is "squashed" although for now it recovers. Was this covered in any VCF E classes this or last year?

I assume there are a few places on the web that describe MAC repairs like these, but any comments as to what to target are welcome and will save me some time.

Bill, Just an FYI, these two books : Dead Mac Scrolls ( http://www.amazon.com/Dead-Mac-Scrolls-MacIntosh-Thousands/dp/0940235250) and Mac Classic & Se: Repair and Upgrade Secrets ( http://www.amazon.com/Mac-Classic-Se-Upgrade-Secrets/dp/1566090229) Are extremely useful books for this type of repair. I use them both a lot on all of the unibody Macs that I'm fixing. Details on what parts drive what in ways that are fairly simple to understand (I just need the guidance as to what part to replace as well... not an EE... I can solder well enough for any sort of repair on these :-) ) I've also got some things for stuck drives (and sources for the gear that can go as well). Earl

Thank you very much. I am also interested in more information about repairing stuck drives. -- @ BillDeg: Web: vintagecomputer.net Twitter: @billdeg <https://twitter.com/billdeg> Youtube: @billdeg <https://www.youtube.com/user/billdeg> Unauthorized Bio <http://www.vintagecomputer.net/readme.cfm>
I just repaired a stuck eject mechanism on a 512k, and used my go-to lubricant... schaeffer's penetro 90. It breaks down the old grease, and leaves lubrication behind unlike wd-40. Someone had removed a disk from the drive forcefully, and broke the plastic piece that moves into the optical sensor to tell the drive when the disk is installed. To fix it I heated up a piece of wire with a torch and melted it into the plastic. After trimming to length it works perfectly. -J On Fri, Apr 29, 2016 at 12:01 PM, william degnan via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:

I went over how to repair jammed up drives in my mac repair seminar at VCFE, and repaired an 800K drive there - don't know if anyone videotaped it or not. I could definitely do it again at the next workshop, if anyone is interested. Can go over 400K and 800K drives. It boils down to knowing how to take the mechanism apart and remove the metal loading part. Then it's just straightforward dissolving of the old grease with your favorite solvent, and relubricating with something suitable, such as lithium grease or silicone lubricant. -Ian On Fri, Apr 29, 2016 at 12:01 PM, william degnan via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
