RM Nimbus VX/2

This RM Nimbus VX/2 machine forms part of our working RM Nimbus Network. It is the second server, and has a 16Mhz 80386SX processor and 2 Mbytes of memory. It has a built in PVGA graphics chip. The CPU and memory are on a ISA expansion card, with only the FDD controller, parallel, serial, mouse and video controllers on the base board. This was to allow easy upgrade paths in the field as all the X series and X/2 series shared the same base board. The original X series machines had EGA graphics, whilst the X/2 series like this machine had PVGA graphics. The mouse connects via bus mouse port.

It runs RM NET 3.0, and will remote boot both Nimbus PC186 and X/M series machines over the network.

It is fitted with a single ZNET controller card which i set to run on its slower speed of 800kbps so that the 186 machines will boot from it as well.

It also has a SCSI 1 card fitted to allow an external tape drive to be attached.
