Looks like Techno, which dates back to the days of Mac OS 8.5, IIRC. Can't remember if it still comes installed on newer Macs, though.

I can’t believe I didn’t think of Techno. It was part of Mac OS up to 9.9.2.

iskippy - you're a star thanks :-)

Jan - I can't believe I didn't recognise it either ;-)

Thanks to you both
