A version of Logger Pro 2 that works with the LabPro interface on a Windows 3.1 PC may be found on the Logger Pro 2.1.1 and 2.2.1 CD. The computer must have Win32s installed (located on the CD or available from the Vernier web site) in order to run. Printing the screen and graphs may require the Windows for Workgroups version of Win 3.1 and may require 8M of memory. Older PC's with slow processors or serial port handler chips may report spurious data at times. This version has had little testing and is essentially unsupported with no future upgrades.
