Emulator 1 wouldn't start

[fainardi83]

hi
i have an emulator 1 when i powered up all del light up and the disk drive seems to not working

do you think it 's a problem of the disk drive?
 when i open it i swan on the right board that there is a place for a ship referenced 17
 do you know that if this slot must be empty or it is plugged wih an integrated circuit

regards

It's normal that socket 17 has no IC in it, so that's not a problem.

When all LEDs are ON after powering up, it means that there's a problem with the floppy drive or floppy drive interface (all LEDs ON is a documented error code)
You could start with disconnecting the ribbon cables from the floppy drive and motherboard, clean all floppy interface contacts (both at floppy drive side and board side), and connect them again.
Also check if the power cables are properly connected to the drive.
Also make sure there is no mechanical obstacle which blocks the drive's motor.

Of course, after 30 years, the Shugart drives may fail. It might need replacement. If you have an HxC, you can use it to check if the problem is really caused by the drive itself or by the floppy drive controller IC.

hello
connector and ribbon has been cleaned up
power is ok on the disk drive , i have +5v and +12v
there is no mechanical obstacle which blocks the drive's motor
the disk drive is also ok

do you think that is the controller interface ? or the ROM ?
