My first computer was a Commodore 64.
My first PC was an IBM XT that Dad pinched from work. It had 128kb RAM, Intel 8088 processor running at 4.77 MHz, two 5 1/4" floppy disks (360kB) and no hard drive. It booted in to a basic interpreter which I didn't know what to do with so he took it back and brought home another one that had a whopping 20MB hard disk with DOS installed. The XT came with a monster of a monitor with an amazing 80x40 character resolution with a vast colour range of green. The keyboard was comprised of plastic keys embedded within a steel casing that weighed at least 2kgs. If someone hit you over the head with it, you'd likely end up in hospital for a few days. The disk drives (floppy & hard) were around the size of show boxes. It's funny how I can store 120gb on a flash disk the size of a finger nail now.
