Bad Capacitors? FM Towns Marty

[SuperDeadite]

So, I dug the old broken Marty out of the closet today.  It will not read CDs, adjusting the laser pot (it only has one) does nothing.   So I finally took the whole thing apart to look at the board (pain in the ass due to tons of shielding plates.

Only thing I could see are these caps.  The have black stuff on top that looks like magic marker.  One swipe with a tissue wipes it off.  Are these caps bad?  I've seen brown stuff from caps before, but nothing like this.

interesting that the black stuff are straight lines, it does look a little like marker. I can open up mine and take a look.

i have often seen old stock parts marked that way.
the pi isnt clear enough to tell is the caps are split on top (prevent) caps only.

[SignOfZeta]

Its just marker. Not an uncommon site.

sounds interesting... I just recently got into the marty, trying to work with it and figure out some things here and there. there really isn't all that much info on the system. I hope your top secret project is some sort of attachable drive large enough to hold a ton of quality marty games

Also, I can confirm with SignOfZeta, its just marker on the caps. the ones i had with the same marker on my board were not part of the cd-rom board, so even if they do need to be replaced, I don't think it has to do with your cd not working. of course i could be completely wrong though.
