I read in the August-September 1985 issue of Micro Cornucopia on page 50, in an article entitled "The 32-Bit Super Chips" by 5 authors from Definicon Systems, allegations that in the 68020: 1. The barrel shifter does not work, 2. The co-processor interface does not work, 3. The data sheet AC characteristics cannot be met. I suspect that, given magazine lead times, and the manufacturer's possible reluctance to provide a bug sheet except with a CPU chip, that these alleged bugs may have been cured some time ago; but I would be interested in seeing on the net a rebuttal from Motorola, and any current information of bugs/ availability of the 68881 floating point unit. In the same issue, the same authors describe the Definicon DSI-32 Co-Processor, which plugs into an IBM PC and uses a 32032, 32081, and optional 32082 memory management unit and 1 MB of DRAM. They mention the following software as being availab|e for their board, C, Pascal Fortran, Assembler/Linker, Library manager/ Programmer's utilities, and a Public Domain software disk. If you don't subscribe to MicroCornucopia and are interested in the 32032 this might be a good issue to request (for $3). Address P.O. Box 223, Bend, Oregon 97709.
