Quote from: spitfire on April 23, 2021, 07:15:30 PMOf course I knew the coldfire existed but had assumed it wasn't object code compatible for the needs of NeXT hw/sw. It isn't.From wikipedia " not entirely object code compatible with the 68000. When compared to classic 68k hardware, the instruction set differs mainly in that it no longer has support for the binary-coded decimal (BCD) packed data format; it removes a number of other, less used instructions; and most instructions that are kept support fewer addressing modes. Also, floating point intermediates are 64 bits and not 80 bits as in the 68881 and 68882 coprocessors."So unless someone can show that NeXTStep/OpenStep would work, I'm going to assume it won't. At very least the FPU math will be different from the genuine 68040.
