Acill's Amiga Repair Thread

[Acill]

Since I got the new 68060 in today I decided to prep Japer80's Apollo 1240 for the 1260 upgrade. I got the 1240 desoldered and the old boot ROM as well. The new ROM is fitted in place after desoldering. Im just waiting for my regulator parts and it will be done. I am sure he will be glad to have it back!

68040 is out of this thing!


Holes are cleaned up and ready for the 060 once regulator is installed and setup.



New Boot ROM all ready to go

Keep up the good work! You are right, I can't wait for my 060!
:roflmao:

Sorry its taking so long. Having to get stuff from Europe is no fun waiting for!

[Acill]

Wow!, that's a lot of work!. What method have you used to desolder the 040?

Vacuum desoldering station. Flux the pins and add fresh solder to all pins. Use the desoldering pump slowly and it comes right off.

Have a family medical issue I have to be at Friday. I will be working to get as ahead on board I have here now before that, but will be out for next weekend. If your waiting on a board to be complete I am sorry for the delay, but I am only one man and am going as quick as I can. I don't like to rush perfection! Please hold off sending anything new before the 20th. I do have a couple things heading out today though if you paid for a repair.

Family does come first, hope you understand.

[Acill]

I would hope everyone does. I have a bunch of older Nintendo consoles and an A1200 I'd love to ask you about once your queue is clearer though!

Monday next week will be a good time. I have a couple of boards I cant seem to trace down the issue on I will be returning and one more I am finishing up on when I get back. That will clear me out mostly for boards with parts in now.

Jasper80's Apollo is now an 060. Just waiting on the regulator to solder in and cleaning it up. A nice low profile fan is also waiting for that regulator to get here.

[Acill]

What's that white film with bubbles on the two corners of the 060 chip?

The original heatsink was held on at those points. Chip came this way when ordered.

Paul,

Can you upgrade my CSMK2 040 to an 060?

I could, but I need parts to do it and the CPU. Here is the parts requirements.

Proper Oscillator for the 060. The one for the 040 would not work. Depends on the speed you want. If you are putting in a Rev 6 060 I believe the can go as high as 75-90Mhz and remain stable. Not 100% sure on the MK II. I am not a fan of OC processors myself. (overclocking above 66MHz WILL make the SCSI Controller fail if you have one and faster clock needs faster memory) I have only tested at 50MHz

A LT1085CM-3.3 voltage regulator to change the board from 5V to 3.3V

Three 1N4001 equivalent diodes.

The rest is all desoldering the tiny jumpers and moving them and resoldering them in place. Your 040 should be socketed if I am not mistaken so its very easy. I also would want to put my standard disclaimer that this is major surgery and if something were to go wrong after completing it I cant be completely at blame I havent killed any yet that were not close to being killed in the first place though.

Worked on an A3000T tonight. The owner needed me to remove the solder and legs from a part that was cut out of it before he got it. HY450 is now replaced thanks to an A500 donation to replace it.

[Acill]

Let the micro repairs begin!

[Acill]

Frys electronics if you have one close. Of not I'd be glad to pick you one up here. They are 18 bucks for the larger ones I use.

Where can I get one of those anti-static work mats?

[Acill]

Never see them on amizon. You can try frys Web site too. If not I'd be glad to grab a couple and send them.

Fry's doesn't have a store anywhere in my state.  I can probably find one on Amazon.  Is it any particular brand?  It looks to be very non-slip with those raised squares.

Thanks!

[Acill]

Thanks for your input. All the ones I've seen on amazon are flat, so, that's why I asked him specifically where he got the one with the raised squares.

Like I said, I've never seen these anyplace other than Frys. I buy them all up every time I see them. I go through them a few a year. I have two now. A medium and a large. I think I saw two more last week. I can get one and put it in your 3000 if you want it.

[Acill]

Whew, this Apollo has some tiny things to move for this upgrade. Here is a shot of the resistor I moved through my microscope. Nearly done with the upgrade!

[Acill]

This Apollo is now an 060 and done!

[Acill]

I have room to accept new work if anyone is interested. Please send a PM and let me know what you are looking to have done.
