It was fully marketed towards professional use in offices and companies. The default operating system is TRSDOS or CP/M and the more commonly (in professional environments) used 8” floppies.
The original TRS80 felt more like a toy compared to this. This machine is very extended, and with that came a very high price. This setup shown here (4 drives) was the most expensive (roughly 31000 guilders back in 1981).
Officially not a home computer, but impressive enough to show here.
