When you say the heads were "separated with a disk inserted," do you mean that the top head is not coming down to the disk surface? Out of curiosity, when cleaning the heads, did you lift the top head to clean it?

Hi folks, I recently managed to score a Mac 512K "outfitted" with a Levco MonsterMac/OverDrive upgrade combination that gives it 2 MB of RAM and an internal SCSI hard drive for a pretty good price! I am quite excited - I've been looking for one of these upgrade packages for a while to compare...

Respectfully - what are the criteria that need to be met in order for the schems to be released?

While plausible - I have certainly received documentation/software under agreements to keep it under wraps for a myriad of reasons - the only reason we know these schematics exist is because he publicly showed portions in his video on his 400k+ subscriber YouTube channel, including an entire...

You were brave to offer a warranty on a mostly-original compact! Q3 is the horizontal output transistor and would be the first part to short if the flyback failed (which all signs point to). Definitely check it. Recap is also a good idea, take care to change the Rifa line filtering caps on the...

Does the section of code you just referenced not explicitly state that if you say "there's no warranty," there's no warranty? What am I missing here? Genuinely not being hypothetical here - I am kinda bewildered. I'm fine being a random on the internet though. Being famous is overrated.

Derek, I agree entirely with what you're saying but I recommend you stop while you're ahead, for your sanity. MacEffects isn't about "preservation," or if they are, only if it's financially beneficial to them. Take a look at a prototype Lisa 2 they sold on eBay not that long ago, and note the...

Quick update on this machine, in which things get even more confusing - I yanked the SWIM and transplanted it onto my personal machine's logic board and it works fine, confirming the SWIM is not bad. I also went through and traced each pad and didn't find anything open or testing unusual to my...

Hi all, I have a Macintosh Classic here I have been working on for a friend during the past few weeks, and at every step of the process it has fought tooth and nail to stay dead! I am at a point now where it has an issue I've never seen before and am not sure how to go about fixing, or even...

No, sorry - prices for Color Classics are insane these days, and I'd be afraid I wouldn't be able to find another reasonably-priced unit. I plan on hanging on to it for a while.  :smiley:

Apologies for the very late post, but here's the other 512K I picked up a little while back. This one is pretty beat up and obviously led a hard life...it's never a good sign when you open the package and immediately get a whiff of nicotine. Gross.  :O I bought this machine as it, like the...

Sweet find! Praying that the flyback stays good for many years to come...  :)

It's been a little while since I last embarked on any conquests, but recently a pair of packages came in the mail bearing gifts! Namely a pair of 512K's with some neat upgrades.  ;-D The first system that arrived is a 512Ke with a Computer Care Mac Rescue RAM/SCSI upgrade board installed. This...

I'm...actually not sure, sorry.  :sadmac:  I can open it up tomorrow and grab a picture of the "track" which the caddy slides into, if it would help.

Are you referring to the stepper motor that drives the heads? I've had to oil that motor to resurrect a few MiniScribes before, as the heads were having a lot of trouble trying to seek. Clock oil works like a charm for this type of thing, use a hypodermic needle and inject some oil into the...

In my vintage computing adventures, I've been acquiring more Mac-related equipment as of recent, and since this forum has a dedicated category for posting about stuff you find in the wild, why not start my own?  :beige: To start off the thread, this beautiful Color Classic came in the mail...

Alright, I've been working on this Plus for the past few days, and some small updates: After making an incredibly stupid mistake on my part (do NOT work on computers when half asleep, kids) the analog board would no longer function at all, and immediately blew the fuse when the power switch was...

Hello all -  For the past few days I've been wrestling with this Macintosh Plus that has some serious analog board issues. When turned on, the system does not chime - it is completely silent. It appears to be dead, however, if the brightness is cranked up nearly to the max, a very distorted...

Thank you so much for sharing! Now I suppose I should dig the card out again and see if I can get it working properly.

I believe I have his card.... :p I purchased mine from Singapore and he seems to be located there as well. (Also, @CC_333 - what he said, thanks a lot for the offer...might take you up on it.)
