In 1991, my mid-level firm having being swallowed by one of the Big 6, everything was computerised, including audit.  But the partners decided to buy six suitcase-sized laptops to be shared between around 200 people. We had to work by hand during the day, then do shifts in the evening, copying our work onto the laptops, each machine visiting as many as three people's homes in a single night. And we couldn't do much about it, because it was 1991 and so many of our other colleagues had already lost their jobs.

I did find it entertaining, though, that I was expected to audit our clients' computer systems for security when every computer the partnership owned had the same (obvious) logon and password.  When one of the precious portables went missing, the assumption was that someone had tired of the house-to-house late shifts and decided to keep one for their exclusive use. The memos became ever more threatening, culminating in the statement that all the portables had an internal log and that Computer Services Would Know Who Had Been Using It. Um...not without a secret inbuilt retinal scanner, they wouldn't...

In 1979 a couple of us put a Pertec fixed hard drive onto an Apple.  One whole meg!  (Gah-zang! Gosh, boy-oh-boy.)
