The PDP8 computers were one of the ?rst computers that were a(r)ordable by a broader range of cus- tomers that contributed in the success of these machines. In 1976, Intersil developed a PDP8 chipset consisting of the IM6100 proces- sor [6], the I/O extension (IM6101) and the UART (IM6402). The PDP8 utilizes a small instruction set. Only eight basic instructions are implemented, which provide enough functionality to compose complete programs. A single board computing system was designed using the chipset from Intersil and a 80C32 based microcomputer system. The implemented computer is a minimal PDP8 computer with an UART to interface with legacy peripherals. The 80C32 microcomputer system controls the memory and the system state of the PDP8 sub-system. This microcomputer system communicates with a host computer via an USB interface. The USB connection is based upon the PDIUSB12 USB controller from Philips. Using the 80C32 microcomputer system and specially designed host software, executables can be loaded into the PDP8 memory and their execution can be controlled. The whole PDP8 computer is controllable from a special application running on a Microsoft Windows host computer. Borland C++ Builder was used to develop this application. This thesis will describe the development process and results of building such a system. The design of the PDP8-computer and the PC host sofware will be presented.
