Yup... they're fun... ;)

I made some short cables for mine with appropriate connectors at either end 
so that they could be worked on out of the chassis. Were there official 
service riser cards for them?

Jim: I'd check the eject mechanism first, I would have thought that to be 
pretty fundamental to operation and independent of reading (i.e. you should 
be able to eject a disc even with other faults present). I seem to recall a 
few rubber bumpers and glued-on pads which can cause issues due to age, so 
getting the disc out and assessing the "mechanical" side of things first is 
probably a good idea.
