Greetings to the List - Carlo, I have been using IDE68K out of Norway for about five years and it is excellent: http://home.kpn.nl/pj.fondse/ide68k/ It includes the 68020 instructions such as bit instructions etc - also floating point. I only use the assembler and download S-records to the MVME177-005 boards that I use. I have never found any bugs etc. Best, Jack At 12:46 PM 7/20/2018, Carlo Pisani via cctalk wrote: ---------------------------------------------------------------------------------- Jack Harper, President Secure Outcomes Inc 2942 Evergreen Parkway, Suite 300 Evergreen, Colorado 80439 USA 303.670.8375 303.670.3750 (fax) http://www.secureoutcomes.net for Product Info.
