Wow, I'll have a look.

You're right, I'll try to find how to start it.

Okok, thanks for your help.

Hi. I just post thread about my broken Macintosh SE... Because of the working-well monitor, I want to try if the CRT can be a monitor that can be used to be AV monitor or something else? Just CRT is the hardest I think. Others can be done easily. I found the schematic and took photo of the yoke...

I think maybe it's not BlueSCSI? But the function is still the same, and it is tested by the seller and works well.

Hi, it's me again.... For last post, I test the power supply carefully, and it finally works well. 5V and 12V both works well. The Macintosh SE DID work. Unfortunately, there's a floppy disk icon with question mark on it. I tried using external hard drive, internal hard drive and floppy disk...

This is my motherboard, and I only replaced one gear in the floppy drive's eject motor.

Hi, the internal hard drive doesn't been replaced, I just put the BlueSCSI for an external hard drive

Oh, I also tried to cut down all the connection: floppy disk drive, hard disk, even keyboard and mouse
