The Holborn System 9100/9200 computer was a Dutch product ("born in Holland") consisting of a science-fiction style desk-top display/keyboard unit, a processor box with two or four 8" floppy drives and a printer. The processor was a Z80 with 64 KB of address space.

There were two versions : the larger one used a proprietary multi-user operating system, one feature of which was the use of a lightpen for much the same purposes as today's mouse. The smaller machine used CP/M without lightpen interaction. The computer was mainly sold to small companies for administration and bookkeeping purposes.

The machine's hardware was designed by H.A. Polak, the console by Vos Industrial Designers. The disks and the system electronics were in a separate refrigator-sized housing (a desktop box for the smaller system); the console shown in the picture mainly contains a converted MicroBee terminal.

The Holborn company was founded in 1979, it's head office was in Holten (Hol born). The company has been active until 1983, when it bankrupted. Like most manufacturers of computer systems of original design around the world, it hasn't survived the competition of IBM and the IBM-PC-clone builders. About 200 machines were sold, 50 of them of the larger variety.
