The Sharp PC-E500S was a 1995 pocket computer by Sharp Corporation and was the successor to the 1989 PC-E500 model, featuring a 2.304 MHz CMOS CPU.
It came with 32 kB of RAM which could be upgraded to 96 kB. The monochrome LCD display had 240×32 pixels which could display four lines with 40 characters per line. The 256 kB system ROM also contained a BASIC interpreter which could be used to program the device. Printer and serial ports were also available.[1]
The PC-E500S had a weight of 340 g (with batteries) and was powered by four AAA batteries. It could, given its power consumption of 0.09 W, be used for about 70 hours on a charge.[1]
The most famous pocket computers were made by Sharp—they released the groundbreaking PC-1210 BASIC computer in 1980 (with 1K of memory) and continued making vastly superior variations until 2001.
