Pump Trainer Revision 4 makes full use of the 32-bit operating systems of Microsoft® Windows® NT, 95, 98 and 2000, greatly enhancing sound and graphics display, while resolving incompatibilities of 16-bit software with 32-bit operating systems that exist on some computers. Revision 4 will run with 32 MBytes RAM (memory), but the sound may be adversely affected. Windows 3.1 is no longer supported, as The Upgrade is a 32-bit application only. All Revision 3 files are compatible with Revision 4. Revision 3 will still operate after Revision 4 is installed. Microsoft® DirectX® is required.

DirectX: Pump Trainer 3 wav and MIDI sound has been converted to DirectSound, a component of DirectX. DirectX was created by Microsoft to enable fast graphics and quality sound. DirectX is downloadable (free) from the Microsoft website at www.microsoft.comdirectx. If you have purchased and installed computer games on your computer, it is likely that DirectX is already installed. For Windows NT users, service pack 6 (SP3 may be sufficient), when installed, also installs DirectX. For non-NT users, download the current DirectX version (now 8.0a) from Microsoft Home User Downloads. DirectX must be installed on your computer to make Pump Trainer Revision 4 sound work.
