The companies with more at stake were because they had been selling 8080 machines running CPM-80 and they were waiting for CPM-86 to come along as that was going to be the new standard. They then took their old 8080 based motherboards and adapted them for 8088, CPM-86 came out but then so did MSDOS. Microsoft did OEM deals that gave you the source code to the hardware specific part of the OS (I think they shipped the source for the SCP 8086 systems that QDOS was originally developed for, not the IBM PC versions of those files). You changed the software to match your board and you didn't need to bother cloning the PC because all the applications will work anyway right? Well soon it became clear that wasn't true & people only wanted to buy clones. But clones were being made at the same time. When I went to college in 1987 the dbase stuff we did was all on CPM, which is kinda insane.Received on 2019-01-12 23:00:07
