This is the early version of the RM Nimbus PC. It is a TN model which denotes it is a network only model, and does not have a disk controller. It would be boot remotely off an RM Nimbus Network servers, via the onboard ZNET port.
It is fitted with 1 Mbytes of RAM, and has the standard 80186 processor. These early models had two cartridge slots on the front, which allowed for a ROM cartridge and also a license control dongle to be inserted. These slots were removed on the later beige coloured machines as they proved to be of little use, as most machines were used on school networks, and software could be loaded off the server negating the need for ROM cartridges. Very few software providers were interested in putting in the development time to use the dongle port - the exception being Auto Desk.
