霍尔本9100，一款几乎被遗忘的荷兰Z80多用户个人电脑
Holborn 9100是由荷兰计算机制造商Holborn于1981年发布的。其外观设计由名为Studio Vos的工业设计事务所负责，开发者为Hans Polak和Henny Beavers。该名称源于“出生于荷兰”这一短语。该产品主要有两个版本：一个是较大的版本，配备了名为Holborn OS的专有多用户操作系统，支持光笔；另一个是较小的机器，使用CP/M操作系统，不支持光笔。这些版本分为四个不同的型号发布：9100、7100、6500和6100。系统主要由一个集成的桌面显示器、终端和键盘组成，外部单元则容纳两个8英寸的软盘驱动器和一个可选的硬盘。6500系列配备了可拆卸的键盘。该计算机主要面向小型企业，用于行政管理和记账。编号较低的型号是在9100发布后生产的。大约生产了200台机器，其中50台为较大型号。由于当时系统的高价为30,000荷尔德（约合10,000美元，折合2023年的30,591美元）以及来自IBM的竞争，该系统在商业上失败，导致制造商在1983年破产。最受欢迎的版本是6100。估计目前仍存活的系统约有20台。

The Holborn 9100 was released in 1981 by Dutch computer manufacturer Holborn. The appearance was designed by an industrial design office named Studio Vos and developed by Hans Polak and Henny Beavers. The name comes from the phrase "born in Holland." There were two main versions, a larger one with a proprietary multi-user operating system named Holborn OS with support for a light pen, and a smaller machine with the operating system CP/M and no light pen support. These versions were split into four different models released: the 9100, 7100, 6500, and 6100. The systems consist primarily of a combined desktop monitor, terminal, and keyboard with an external unit housing two 8-inch floppy drives and an optional hard drive. The 6500 series had a detachable keyboard. The computer was primarily marketed to small companies for administration and bookkeeping purposes. The lower-numbered models were produced after the release of the 9100. Around 200 machines were produced, with 50 of them being the larger models. Due to the high price of the system at the time at 30,000 guilder or $10,000 USD (equivalent to $30,591 in 2023) and competition from IBM, the system was a commercial failure and caused the manufacturer to go bankrupt in 1983. The most popular version was the 6100. It is estimated that around 20 systems survive.
