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.

#2There were a lot of high end machines based on CP/M and MP/M circa 1980. They hardly get talked about in the articles in Byte magazine but their manufacturers like Cromemco dominate in the advertisements, particularly in the premium ads near the front and back. I think these include machines that have one Z80 that are multi-user as well as machines that give each user a Z80.

the URL box didn't let me post the submission when I hit submit, nothing was happening and it only worked when I removed the URL field, possibly some sort of bug
