I remember when...
Back in 1990, I was reviewing databases which were to run as NLM (Oracle, SqlBase, a few others). MS provided my with SqlServer for NT. When I pointed out that we didn't have NT, they provided it. On 35 floppies.
After 12 had gone back to MS with read errors and I said "No More", they asked if the machine had a CD drive. "Sure does," said I. And so I got a new installation: three floppies and a CD.
Disk 1 booted: no problem
Disk 2 loaded: no problem
Disk 3 loaded: no problem
Then I got the message: "Please insert the Windows NT CD-Rom into drive A: and hit any key to continue..."
