I don't have experiance with ireland but I do live in the UK and I expect the situation is similar.
In the UK one commonly sees generic "visitor" adaptors. These are widely available in most supermarkets and many other shops. They will look something like this:

Typically they will accept american plugs, australian plugs and most European plugs. They may also accept 5A BS546 plugs (often listed as indian plugs). They will almost certainly NOT accept 15A BS546 plugs (often listed as south african plugs).
German/French plugs will typically be accepted but will not be earthed.
Unfortunately while the generic adaptors are as common as muck (at least in the UK but from the other answer it seems similar in ireland) if you need something that they don't cover you are likely to struggle. You might find earthed adaptors for German Shuko plugs with some searching. Anything else will probablly have to be ordered online.
Rewirable plugs should also be fairly widely available so if you are really stuck then changing the plug may be an option.
For computer gear getting a new power cord may also be an option.

Tourist-junk shops will normally carry them. So, anywhere you see selling Shamrock-themed tat and big green Leprechaun hats are worth a shot.
Homeware and electricals stores are also an option - as can be DIY stores.
Particular places I found that advertise them online and might have a store near you:
All these I found by searching "travel adapter" on google.ie. (Although most of the linked chains I know from the UK).
Be careful if your device needs earthing, that the adapter you use properly passes the earth through. Many of the adapters shown either don't, or only do for some types of plug (and Europe has many slightly different types)
