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.

[1] The computer was primarily marketed to small companies for administration and bookkeeping purposes.

[5] The application software was menu driven and could be controlled by a light pen to aid use by technically unskilled users.

The goal of the company was to supply computers based on microprocessor technology to specific types of retailers.

Due to competition from more popular IBM computers, Holborn remained dependent on financial aid from the Overijssel development company OOM.

[7] Inexhibit noted that "The design of the Holborn set it apart from most computers of the time," calling it futuristic and organic.
