Super easy if they are 'Okay'... a basic service just needs a few sockets, circlip pliers and oil. Plus the needle shock pump.
Here’s a link to the service manual:

Back in the 90s I worked at a bike shop where I was the RockShox trained mechanic, this manual certainly helped me remember the things I’d forgotten since leaving the trade...just a shame I dont have all the specialist tools anymore.

Re:
Yeah, you'll find that and more in the archive here http://www.retrobike.co.uk/gallery2/v/M ... e/Service/
The cost of a full service is not really in my opinion worth it for the fork, unless you do it yourself.
I've services quite a few and rebuilt from part many over the past 10 years or so I've been on here.
When you get them
- Pump them up, you'll need needle in a pump (basketball/football) to do that.See if they then piss the air back out.
If not, you're good for now
Then pop the caps off, poor some oil out see what it looks like.
If horrible or you just want to do it anyway, buy some 5 wt oil, unless you are on the heavier side (see sutherland tweaking manual) and add a bit to each and flush out what you can a few times.
Then fill with out, fit caps, set the oil level and pump up and go for a ride (you can buy nice pumps of ebay that have a dial at the low pressure up to 60 PSI range).
If they loose air over time, you can make/buy/get me or somebody else to fix the air seals for you, should be no more than a tenner maybe.
Give them a go and tweak.
If other stuff happens, like oil out the main seal or warn bushes, they can be replaced but you need to split the forks apart.. which can be done at home without the tools most of the time.
Have fun, have a go, oil doesn't cost that much.

I'm going to try to refurb the fork. I have another for spare parts and I bought the two o ring seals so here's hoping it works
