TL;DR: A portable computer system with the full functionality of a desktop computer is designed in this paper, where components are arranged in a highly space efficient manner, such that the main system unit includes a removable keyboard, a fold-up display screen, floppy and fixed disk drives, and an internal modem.
Abstract: A portable computer system with the full functionality of a desktop computer is designed so that components are arranged in a highly space efficient manner. The main system unit includes a removable keyboard, a fold-up display screen, floppy and fixed disk drives, and an internal modem, and has both external AC and internal battery power supplies. The system further includes a desktop expansion base into which the main system unit can be inserted, providing additional functionality for the main system unit. The components of the system are arranged to provide a convenient and efficient user interface.

TL;DR: A flexible data entry program accommodating severai experimental designs was written in BASIC for creating anaIysIsready data flies, using either keyboard or RS-232 data input.
Abstract: Recording and management of field or laboratory drta can be aided tluougb use of a data logging computer. Data are eiectronicaiiy transferred from the data logger to a larger computer for statistical analysis, eliminating re-entry from field sheets and reducing the potenthi for error. Laptop computers offer advurtages over specialized data loggers, but require a software program to function efficiently as a data logger. Range reaearcb uses migbt include recording plant sampie weights, recording iivestock weights and condition scores, pi& growth measurements, and frequency counts. A flexible data entry program accommodating severai experimental designs was written in BASIC for creating anaIysIsready data flies, using either keyboard or RS-232 data input.
