Merci beaucoup, mike.

I hadn't done the right record-keeping to discover the actual units.

They've been running for 6-7 years, not two, so that works out.

Units are three hour periods - See the 58503B Operation and programming 
guide, 5-71.
HP were pretty confident in the lifetime of their product as they allow 
a 4 Gig count before rollover.
