Philips started back in 1981 with producing the first home computers. The P2000T and P2000M were the first. Followed in 1983 with the P2000C. This last machine could have an extra CPU-card in it, making the machine able to run MS-DOS. In the following year, Philips bought the Canadian company Corona (not the virus) and created a fully IBM PC-compatible machine, the Philips P3100 (which was a rebadged Corona-computer). However, the machine was slower than IBM's. It took until 1988 before they were really successful and that came with the P3105 or NMS 9100. The P3105 was the business version of the NMS 9100, but they only differ in badge. They came standard with the 8088 CPU running at 4.77 MHz. However, if you press alt-shift-shift the CPU goes to a whopping 8 MHz. Also special is the IDE-interface on these XT-class machines, XT mostly used the MFM-standard. There were several configuration options. Either Hercules or MDA (both monochrome) to CGA and even EGA. 768 KB memory was standard, as was the 5,25" 1.2MB…
