Ouch!

£1 = 3DM roughly, iirc?

The first PC I *bought* was a Pentium (actually a 686), but seeing as I 
started work as a programmer immediately on leaving school I had access 
to old computers my employer(s) were scrapping.

The first piece of hardware I remember my employer buying was one of 
those 300MB drives - you know - the ones with the 10-platter diskpacks, 
and the size of a domestic fridge. It quadrupled our storage capacity!
