Agreed. This is why every non-highly compatible MS-DOS computer, like the Tandy 2000 and TI Professional, failed versus IBM. Even if a buyer only intended to use Lotus—widely ported to various MS-DOS non-compatibles—he would always have in the back of his mind "What if I want to run something else? What if I need to give a disk with data to someone with IBM?" > Hyperion never purported to be PC-DOS compatible and as noted it > wasn’t even offered as generic MS-DOS compatible. I was amazed to not see on Santo's February 1984 list of Hyperion-certified compatible software Lotus or Flight Simulator. The latter, I can understand. The former made Hyperion dead on arrival. -- geo:37.783333,-122.416667
