Initially I assisted in the development of the system on a consultancy basis, and later I was involved through coastline computer consultancy in the porting and development of the system to a number of different hardware platforms based on the Z80 and 68000 processors.
The image shows the boot up screen of the Beaver 1 Computer running on a emulated Z80 system hosted on GNU/Linux/X which I created to assist in transfering some data from an old Beaver 1 Computer.
The emulated system is called xbeaver. A version of it is available for download.
