Much of what was said in the first review still applies. But this version, in addition to running under Windows instead of Dos, has had several significant new features. Being 32-bit throughout, Proteus IV needs the WIN32S driver to be installed before it can be used with Windows 3.1. The two components of Proteus IV, namely Isis and Ares IV occupy 9.5Mbyte of disk space. Other versions with different pin limits are available.
Security is by registering name and number.
The manual is a single large volume, well written and concise. Labcenter has its own terminology for many items, but explanations are given. References to the dos version have now been removed, making the manual easier to read. It is split into three sections covering the schematic, layout, and simulator program supplied as an extra and each section has its own comprehensive index. This sub-package has taken on board much of the character of Propak's Isis Illustrator.
