Starting at some point in the 1980’s, my grandmother worked for IBM in the clean rooms manufacturing semiconductors on silicon wafers. This was one of the keepsakes that they gave her during that time: 1 Megabyte of RAM encased in a protective bubble and mounted on a keychain!
She entrusted me with it when I was in high school, considering that my technological inclination was more than apparent by then. I look forward to visiting her again.
Poqet PC (1989)
The Poqet PC is a very small, portable IBM PC compatible computer, introduced in 1989 by Poqet Computer Corporation. It was the first subnotebook form factor IBM-PC compatible computer that ran MS-DOS. The Poqet PC is powered by two AA-size batteries. Through the use of aggressive power management, which includes stopping the CPU between keystrokes, the batteries are able to power the computer for anywhere between a couple of weeks and a couple of months, depending on usage.
