Here you go Terry, proof positive (and mine came from eBay too):

It's worth remembering though that Office 2003 will truncate the huge Excel spreadsheets such as the one lurking in the background as it can't support the huge number of columns. I did have a copy of Office 2010 and I found it utterly hateful (it lied when I tried to produce a table in Word with fixed cell sizes).
For some reason (it is explained on the Internet) you can't change the default colour scheme of the programs on this machine (Windows 10 64-bit) but it's a small price to pay.
