Thought this was interesting

I find it interesting that the timeline notes the invention of the floppy disk at IBM in 1967 but fails to note the invention of the hard disk drive at IBM in 1956.

I'm sure there are other things that may have been missed but something as significant as the disk drive?
 
What was the size and price of the hd then Strollin. I know i didn't have one. a 8" disc was 360k and i think $500 during the day. I still remember much of it though. just 4k of memory and max was like 32k. and expensive.

Would tend to agree with this observation. Was so basic to the development of the computer.

The first commercially available disk drive was the IBM 350 RAMAC, it could store 5MB of data and leased for $3,200/month. It had a stack of fifty 24" disks with two access arms that moved up and down and in and out to access the data on the disks. It was about the size of 2 large refrigerators put together and weighed over 500lbs.

It wouldn't have been something that could connect to a PC, mainframes only so it's very unlikely you and anyone you knew would have one. Banks and insurance companies with large data centers were the first customers.

These predated the 8" floppy by almost 10 years.
