The office equipment store in Cambridge opened when I was a fourth year
student; late 93 or early 94.

Sounds plausible. And probably makes it the second.

Before that it was a DIY store -
Homebase? Before they took over Texas and moved to the Beehive? I could be
wrong.

I wasn't around Cambridge in those days. Before that it was a Car
Showroom (as was that row of shops in Jesus Lane).
