The TAM is a PowerMac 6500 in a different case and with a PowerBook (3400) screen and keyboard. The PSU is a PowerMac unit or close to.

If you had a chime, probably the voltages are ok. So looking for any hardware issue is a good starting point (bad Ram…)

Bad heads or head not clamping enough the disk. Are the heads clean ? Can you swap heads (from one not working drive to another)

Have you tried connecting the external drive directly to the internal cable for a test ?

I have not worked on a TAM often, but capacitors are not always the magic solution. Are you sure you are getting all voltages required from the power supply ? Try removing any card present (if you have) remove the HD and try booting with a basic setup. If no improvement you can have a look at...

Yes no issue if you only remove the drive.

I tested my 5300 this week-end and the screen is worse than the one posted by Indibil. I think i have a spare but not a 100% sure... the 5300 has been kept in a steady temperature place for many years,... and the HD is bad as well.

there is so many battery bombed boards around, easy to find a good case if you are looking for one...

Still thinking you have got a broken trace, probably appeared after the recap, or a nasty sound chip. The sound chip is nearby two 47µf capacitors

Yes, i will say the same thing, never seen that before but probabaly an issue with the board, cable or component on the LB. you cannot complain, you have a second drive for free.

This is typical from bad caps and low voltage. Check for the 5 volt rail at the HD Molex. Don’t much you can do until caps have not been removed.

Hi, to be honest a $100 was far too expensive, $50 is not the biggest deal of the year but is decent. A mouse is required, but the keyboard is not mandatory and $30 is a fair price.

The Classic is happy with 4,85 volts in the 5 volt rail, below at best zebra bars with the shaky screen. Analog boards are all bad until caps have been replaced (and not only, because those boards are cheaply made)

5 volt rail is a bit low…try to crank it up to 4,8 There is a potentiometer on the side of the AB. Try reflowing the solder joints at the usual places.

I will check voltages, you are getting a clear chime, so not bad, most AB are dead and not delivering any. Can be a bad solder joint, don’t see any hot spot either. But those two RIFA caps should go.
