Looks like it's a Victorian version (as opposed to NSW or QLD etc.) going by the Tatts logo on the screen - don't know if it can be QCOM'd like certain other machines but AFAIK Tatts machines from that era (circa 2002) used the VLC protocol rather than QCOM. Nice find though, haven't seen that machine in years, idiots kept ruining it by setting it to 5c which was a ripoff (it's meant to be a 1c game but Victorian venues do stupid stuff like that all the time).
IIRC there's a way to force some IGTs into a "test" type mode which bypasses the comms and lets you insert coins/notes and play like normal, unless it's another company I'm thinking of. Can't confirm if it's possible on Victorian machines though.
