My first computer was a Sinclair ZX Spectrum, 48K RAM, AFAIR. Rubber keyboard and tape recorder storage, hitched up to the TV. Hard disk? What hard disk?!
First proper PC in the house was my father's - a Philips 8088 with a massive 20MB hard drive and 1 MB RAM. DOS 2.X, I think
My first was a relatively recent 486SX 25 with 4 MB RAM and 100 MB disk. DOS 5 and Windows 3.1
We've all passed as lot of water since then, as Jack Warner would have said!
