This is the best i could do so far, i watched some videos in the past but this is my 1st time really using a scope.

It's an old philips PM 3260 E and i dont see any test point

I just got my scope working, would you know a simple test to see if it's working or if the last owner maybe broke it messing around with it ?

Im ordering probes for my scope because i need to learn how to use it and i need it for other projects, im a real noob with scope so i will watch videos to learn how to use it and maybe do you want the manual of the scope i will use, so maybe you can help me with it if i have problems ?

I have a scope but it has no probes so sadly i cant work with it

On pin 2 i get 12v On pin 7 15v And on pin 16 10v

I will reflow all solder connections today. and does someone have a pinout or something similar to check the voltages of the analog board ? Since the hard drive is spinning up i believe the 12v rail is okay but theres not boot chime or activity so there might be a problem on the 5v rail

Here are the schematics i found for the macintosh classic ii

No, it does not appear burned

Hello, i have a faulty macintosh classic ii with vertical collapse, what schould i look for on the analog board ? Considering the hard drive is spinning up means the problem might only be on the high voltage part of the board ? Theres also no boot signs of the motherboard.

Hi, can you help me identify this old and strange portable computer ? All i know is that it has a pc size asus motherboard p3v133 and a pentium iii ?

Schould i replace them with 10uf 16v electrolytic capacitor or stick with tantalum ?

Hello, i need help to confirm this tantalum capacitor is correctly a 10uf 15v

im really sorry for not responding anymore but something happened to me and i can't come anymore to the home where i stored the cbm, it's seating stored here sadly. I will come back when i can pick it up. And happy new year by the way.
