Part of the reason they're not terribly responsive is that they need to
look up practically everything in the store controller. The IBM ones
contain a 4800-series EPOS machine, with a 1GHz PIII in iirc. No excuse
for them to be slow, but the store controllers are very low-end Pentia
and are driving all the database stuff for *every till in the store*...
When you reboot a 4690-type till, they netboot off the store controller.
Lunchtime on a Saturday, this goes *very* slowly.
