Classic II cure not so curative - a mininovel with photos :P

HEY jt I beat you!

... That's still only 80*80, the original is 512*512 which is far more agreeable!

Not to derail this nice tangent, but about the board? What are your thoughts Mars?

15 AU/ 10 US? Plus Shipping? I can get it to you this weekend and then I can take pictures and send them to you.

Oh and also found the 512x512 image. Will modify that one today

Ok... Uh, I hope you'd excuse the request, but would it be able to be set for /next/ weekend please? I'll need to have money to give you, and that happens next thursday (not tomorrow, but the following) - because basically I'm intending to pay you!

I'm about to go poke trag with a list of caps, which hopefully I'll be buying the same day.

Thanks kindly!

No problem, that's even better.

The saucer that sticks to the classic on the side? I don't have that... The soonest I could get it to you is this weekend. Hey someone here name a price for what you think the Lobo is worth, I have no idea.

First, find out how much it would cost to send the logic board to Sydney. Then, based on that price, figure in how much the Classic II is worth in today's money.

I hear Classic IIs aren't that expensive today, what with all the iMacs that are out

Midnight Commando: Please tell me you have indeed burned your fingers in the attempt to solder/desolder your project. If so, you have earned our respect as a hardware hacker. In a way, it is one way to be considered one of the elite. Don't give up, though. Your experience will get you somewhere.

A very long time ago, when I was repairing a PowerBook 1xx (I don't remember the /exact/ one) for a friend (battery issues) I actually gave myself significant burns across my hand while I was working - I didn't know at the time that the cells got so hot!

And also, I have burned my fingers, yes - electrolytic caps make WONDERFUL heatsinks!

Until new pictures of your current Logic Board are posted, it's hard to say if whether you're flogging a dead horse or if it can in fact be completely revived.

I'll post a high-res photo of the area with the two stripped pads/tracks when I get back from breakfast. Hopefully that will be adequate to determine what's going on I'll probably try to get that logic board off Mars anyway - and if I get this one fixed, I can use it as a spare, or give it to someone who has a screwed Classic II

This is ending up to be more trouble than I anticipated. But never will it be more trouble than it's worth

Electrolytics do make wonderful heatsinks, they also make wonderful firecrackers when they get too hot, not that i know this from experience or anything..... }

Also you need to pick up some Xerox film remover, which is a very strong alchohol much better than regular rubbing alchohol. Also a can of MG Chemicals flux remover will do as well, that way you can clean up that whole board nice, and youll figure out right away where the pads and traces connected to. with all that crud, its hard to tell....

I used regular through-hole radial electrolytics, bending leads and soldering on top just like you did, on my SE/30. it still works to this day. just have to do it right.

Ok, I've fixed that right up, I hope :b&w:

If I might beg your indulgence just a little further, could I please get close-up photos of the caps on YOUR classic II board? It seems that the amount of caps varied a little between some of the boards, and as i'll be getting the caps and the board at the same time, it will be a huge pain if i find i've cocked up.

I dug out my AppleCD 150e also, long dead however I liberated (along with the Classic II and the Macintosh and the IIvx) a tray-loading AppleCD 300i Plus, which I have electrically and physically hacked into the enclosure, so I now have what will be a working CD-ROM drive for transferring files it seems

I have the cable for it - cn-50 to db-25, however I have not got the terminator brick. Once I have figured it all out, I'll start a thread in Hacks on how to make your own passive terminating resistor block - at the moment I'm just poring over the spec.

Thanks again for all your help! I'll be in touch via privmsg closer to Thursday so things can be sorted out
