Sharp PC-1403 Pocket Computer Introduction

The Sharp PC-1403H was a small scientific calculator and pocket computer manufactured by Sharp. It was the successor of the Sharp PC-1401, and had better display, more RAM and better system software. Here’s a PC. And by PC I don’t mean personal computer, but pocket computer. You could also call it a calculator, because that’s exactly what the Sharp PC 1403H is. But one that can be programmed. It’s not far removed from a personal computer of the time. The Sharp PC-1403 without the H suffix, i.e. with only 8 instead of 32 KB memory, has been around since 1986. What we’re looking at here is technology typical of the 80s. The one I have is from around 1993. Back then, I used the pocket computer for math lessons at school. Similar to a Commodore C64, the Sharp PC is programmed in BASIC. Although the screen only consists of one line of text, simple graphics can also be programmed using the PEEK and POKE commands.
