The Holborn 9100 was an 8-bit personal computer the Dutch company Holborn introduced in 1981, built around a 4 megahertz Zilog Z80 processor with 72 kilobytes of memory expandable to 220 kilobytes and running CP/M or the machine's own Holborn OS. Designed by Studio Vos with development by Hans Polak and Henny Beavers, it combined a desktop monitor, terminal and keyboard with a separate unit holding two 8-inch floppy drives and an optional hard disk, and was aimed at small businesses for administration and bookkeeping. Its roughly 30,000 guilder price, about 10,000 dollars at the time, and competition from IBM limited it to around 200 units sold before Holborn went bankrupt in 1983.
