Posible conquest: LCIII!

[JRL]

Unfortunately, you are wrong. The Quantum ProDrive ELS that was originally installed in my Macintosh LC 475 died a while back. The Quantum ProDrive LPSes/LTs are the good ones and are really reliable. Best of all, you can find them almost everywhere.

I might be willing to let go of one of one of my 300 MB SCSI HDs for a reasonable offer.

I've owned.....5 ProDrive ELS's over the years, one of which was brand new (it was in our LCIII, which Dad bought brand new back in 1993). All of them are dead. I've also owned.....3 ProDrive LPS's over the years, 2 of which are still going strong. As JRL said, with Quantum drives, ELS = bad, LPS = good.

especially for machines setup in such a way that it becomes more difficult to reach around the back for the power switch.

Perhaps with all these advances in technology they'll work out how to put a power-switch on the front!

Soft-power can be a bugger when after a power-cut the machine insists on turning itself on. I have a number in my rack like that, the problem then is they all start up then blow the trip switch on the rack.

Oops! My uploads hung and only the first couple of photos were uploaded.

Forgive my ignorince here, but IIRC, aren't the "pizza box" macs one of the few without capiciters?

 

[macgeek417]

...And (finally) Pics!

 

[JRL]

No, the pizza box series does definitely have caps, and when you hear a squeaking sound, it's likely that they are going.

I doubt yours has that problem since it would have been mentioned by the seller though.

 

[macgeek417]

Aah. I'm assuming the caps are on the bottom of the mobo?

Also, what model(s) dont have caps?

And the caps appear to be fine. No squeaking noises here!

 

[JRL]

Nah, the caps are on the top, like the small "can" like thingies you see on the motherboard.

I believe every Mac has caps, but the SE/30/Classic II/Classic/SE/IIci/II/IIx/IIfx/LC I/II/III/maybe 475/Quadra '040s are the ones that are more prone to them leaking.

Even if you don't hear squeaking/a lack of loud sound, it is still a good idea to check the motherboard for leaking caps (if you see something that looks like dried Coke on the motherboard, it is cap leakage).

 

[macgeek417]

I know what caps look like. there are none on the top of the mobo. It looks like the 68030 chip is on the bottom too.

I know what caps look like. there are none on the top of the mobo.

:lol: You obviously don't know what they look like. I can see them on your photos quite clearly. This is what they look like:

 

[macgeek417]

Oh.... I was looking for the big black-with-a-white-stripe gas tanks standing on their soldered on contacts

 

[macgeek417]

Wow! I just looked at the mobo and it appears that 7 of the capiciters have been reworked!

I'l post a pic here in a moment.

 

[macgeek417]

 

[JRL]

No, those are the different types of caps (the ones that don't leak often) that are normal on a LC board.

 

[macgeek417]

Gotcha. OK: What is the reccomended system to run on an LC III? I am probebly going to put 7.6 on it.

 

[JRL]

That RAM chip you have there seems to be 16/32 MB. If my assumption is correct, go with System 7.5.5/System 7.1.

 

[joshc]

Go with 7.1 - it is just as capable as 7.6, and it will run faster and use less RAM. For future reference - there are three common types of capacitor (there are plenty others, though): Radial lead, with a stripe down the side indicating the negative lead, tantalum, the yellow-ish ones, and the round metal can type, the ones that tend to leak. Also, the '030 chip, and all the other main ICs, are on the TOP of the logicboard - 99% of the time this is how its done on ANY printed circuit board. It's labelled clearly on most of the chips what they are.

 

[macgeek417]

Many apps require 7.5, and i want to run the newest OS it can run. Even if it is slower than 7.1.

Besides, i want to have fun doing over 19 disk swaps and writes } .

Yaay 19 floppy set of 7.6!

EDIT: and dont forget the 4-disk 7.6.1 update!

 

[JRL]

The easiest thing to do is run two System Folders, one with 7.5.5 and one with 7.1, and use System Picker to switch between the folders.

 

[macgeek417]

No... 2 system folders would occupy too much space on my puny 80MB ProDrive ELS.

I'll just install 7.6.1; i allready converted all 19 install disks and its disk tools disks to a format.dsk files that i can write with rawrite.
