Flight involves leaving the earth. Could be space flight.

Clue: It is a monster sized version of a common today item. They made even bigger versions back in the day.

Sure looks like a hard drive. I used platters like that to make end tables when they were a common item in thrift stores.

Alright. How big were the platters and what was the storage capacity? This is for the win.

I know one of you know what this mystery drive is. I'm about to call it to a end and just pick the closest for a win. If you have a answer please post it.

A hard drive is a hard drive is a hard drive. Even one as ancient at this. I was hoping someone would have a little more information about this model. I would have accepted even the platter size of 14 inches.

The IBM 3380 Direct Access Storage Device was introduced in June 1980.[40] It used new film head technology and had a capacity of 2.52 gigabytes (in effect, two 1.26 gigabyte devices within one chassis) with a data transfer rate of 3 megabytes per second. Average access time was 16 ms. Purchase price at time of introduction ranged from $81,000 to $142,200. Due to tribology problems encountered between heads and media, the first units did not ship until October, 1981.

In February 1985 IBM announced a double density version - the Extended Capability Models of the 3380 (3380 E) having 5.04 gigabytes per chassis, that is, two 2.52 gigabyte devices in one chassis. A triple capacity version, the 3380 K was announced in August 1987 having 7.562 gigabytes per chassis, that is, two 3.781 gigabytes per device.

I will give the win to Carlos for at least suggesting the platter size being of end tables. Pm as usual.

Ok here is a tool that I had never seen before. It is related to something common but I am looking for the thing it is used on, not just what it does.

Used for polishing / burnishing metal, probably bores.
