A Casio pocket computer, with 1K RAM, then a Commodore 64. I got both almost at the same time, and used them for different things. The Casio stopped working after it got drowned in its second flood. The C64 only got dunked once. I used to dismantle and dry them. Eventually I got a floppy disk drive for it. Boy, did it sing then! But I'd bet there are heaps of us who fondly remember our adventures with such gear at the time. Am.
