Yes, probably an issue with the logic board. Half working if i can say, the chime is a sign that the logic board is ok (Ram, Rom…)

Hi, board doesn’t look bad at first glance, but i see a bit of corrosion on the battery area (near C12)

Probably a chip on the board, can have a look. The eject command is on pin 9 of the connector, then you have got the Q7 transistor (BV4) now 2SB624, probably this one is bad.

Probably have two units, maybe a third somewhere. One is 1Gb the other 2Gb. Not the more reliable devices… but PSUs are ok si far.

the keyboard is not really required, but you won't do anything without a mouse. probably easy to source. I have got several, but i am not in the same side of the Channel.

Yes, good price i agree, The twin drive is scarce nowadays, most have been modified in some way or another. if both drives are working properly, you have got a nice unit.

Yes » Kernel OK « for any Unenhanced IIe and « System OK « for Enhanced ones.

Too slow will not work either

I will rather say the drive is spinning too fast. You can calibrate the drive to the required 300 rpm or better 299 rpm speed, using any Iphone or Android phone with the right application. I am using strobe tachometer, and the bottom white and black target to do so. If the right speed is...

Never seen a Led at this position. The only one which is present by default is the power Led, on the upper left side of the board.

Bad or weak solder joint at J1

Not your issue here, but yes you can replace that cap, won't hurt. Several logic boards were available for the IIe, some with sockets for most chips, some without. You can try swapping the first (on the left) chips with some from the right if those are socketed. The rams chips are on the...

Yes your issue is on the brightness side

i will think this is related with voltages from the PSU, (apparently already adjusted but the former values where already far gone) As cheesetraws suggest, will check voltages at different stages.

Not easy to help you at this point. Finding the short is only possible by removing components one by one until is gone. Any capacitor nearby ?
