2.x 3.00 3.01 3.02 3.04

MS-DOS

Summary: Support for the following math coprocessors has been available in Multiplan since Version 2.x:

8087 80287 80387

The difference between Multiplan Version 3.04 and previous releases is that we changed the way we worked with the coprocessor to be more compatible with clones. Multiplan previously demanded that the system be so strictly compatible with IBM’s 8087 handling that many clones failed to meet that level of compatibility. This included some of the PS/2 models. Version 3.04 gives up speed in order to be more compatible with clone systems. Such a problem has been reported while using a Zenith Model 40 and Multiplan Version 3.00. A system hang occurred when an 80387 chip was installed and a formula was entered. Upgrading to Version 3.04 corrected the problem.
