## 11/29/2024 - Cleaned case with soap and water - Final reassembly (BlueSCSI disconnected - needs a longer cable) ## 11/27/2024 - Replaced eject gear on floppy drive - Got internal BlueSCSI working and booting ## 11/22/2024 - [Serviced](https://www.youtube.com/watch?v=eC1nUblJpwQ) and tested floppy drive - it works! Very well! - The drive was *extremely* dusty, presumably from air intake through the drive. - Did not replace the ejection gear - hasn't arrived yet - Removed hard disk drive - it powers up but does not function ## 11/19/2024 - Reassembled the SE for testing after recapping the analog and PSU boards - It intermittently powers up to big vertical lines (no bong), which possibly indicates failing RAM. Will remove and clean the contacts on the RAM sticks. ![[Pasted image 20250119202154.jpeg]] - Did finally get it to boot from internal and external floppy drives. HDD powers up but is not recognized at all - presumed dead. - Floppy inject is very weak, eject works but is weak. Reads disks. It's a SuperDrive! - Ordered BlueSCSI V2 internal drive. ---- - Removed RAM and ROM chips and cleaned all contacts with 91% IPA. Computer still sometimes shows black & white bars on startup, but will eventually boot if power cycled a couple times. - With the Poking Spoon, when I poke the analog board connector of big cord that goes to the logic board, it can resolve the black bars. It can also cause a reboot and a BONG again. So I suspect a cold solder joint on this connector, similar to the Plus. - Yup! Found cold solder joints on that connector AND others. I re-flowed the solder to all those joints. Seems solid now, although bars appear VERY briefly on startup before the bong (normal?). ![[Pasted image 20250119202209.jpeg]] ## 11/18/2024 - Replaced 60x25mm fan with Noctua brand ![[Pasted image 20250119202221.jpeg]] - Re-capped the power supply. Found evidence of leaky caps. Examined and repaired potential cold solder joints. ![[Pasted image 20250119202255.jpeg]] - The -12V line still reads around -9V (fluctuating) without any load. Will reassemble and test it in the PC anyway, maybe it just needs a load. ## 11/15/2024 - Re-capped the analog board - untested until the computer is reassembled later - Scrubbed down logic board with toothbrush and q-tips and isopropyl, which cleaned up some of the rust; no damage on the bottom of the PCB ## 11/14/2024 - First power-up: fans spin, boots up, looking for floppy - Tried to put in a floppy, it froze, power cycled - Now screen is stuck with vertical bars - Poking things seems to help a little bit - Back the floppy icon now. The disk drive DOES eject but it won't read any disks on startup - No light or activity on hard disk - Analog board - No signs of leaky or bulging capacitors - Power supply - +5V and +12V are okay, but -12V is reading at -10V - Some signs of capacitor leakage - I ordered the wrong capacitor kit… it's not a Sony CR-44 power supply, it's an [Apple 820-0385-A](https://console5.com/store/macintosh-se-30-power-supply-apple-820-0385-a-hitachi.html) - Digital board - ER3S 3.6V (1/2 AA) battery is dead, no signs of battery leakage, but some corrosion (from previous battery? humidity?)
