Caps list for X68030 twin tower

[stt1]

Hello there,

I had to change caps to two broken X68030 computers and they both revived after changing the caps. Quite a job, but here are you the list of caps, if you need to do the same. I recommend you to take only few "aluminium can" caps off at the time and change them to the tantalum type caps straight away, so you wont make errors. Also, if you do this all the same way using SMD-type capacitors as I did, take a careful look on the casing sizes. There are four different standard casings for the SMD tantalum caps and only 2-3 of the casing sizes are suitable depending from the cap you're chancing. I used myself couple of hours for measuring and selecting the correct sizes and good prices from Farnell catalog, but it was worth it! If someone needs, I can pass the Farnell codes for the caps I used. Cheaper method is using non-SMD caps though.

NOTE1: Some C-markings were very tightly printed in the I/O-board, so I'm not sure if they are all correct. Values for caps are correct though.

NOTE2: I did not touch to disk drives, they were still working well, so no list from them.
