PDP−8 on an FPGA a Case Study in Obsolescence Management
PDP−8 on an FPGA A Case Study in Obsolescence Management Eur Ing Dr Martin Bishop CEng FIEE [email protected] www.Emeritus-Solutions.com PDP-8 Photos © David Gesswein - www.pdp8.net Emeritus Solutions Ltd Abstract Key issues in the obsolescence management of embedded computer systems are considered, using the re-implementation of the PDP-8 a classic 1960’s minicomputer on an FPGA as an exemplar. The interplay of system, software and hardware obsolescence is identified. A brief review of obsolescence in general and software obsolescence in particular is presented. The fundamental role of intellectual property rights in enabling obsolescence management is illustrated. The critical contribution of sentient software and system design expertise is emphasised. The re-implementation of a diskless Digital PDP 8/E on an FPGA is described. © Emeritus Solutions Ltd, 2008 Page 1 Introduction System and Software Obsolescence • IP is essential : Rights, Documentation, Media • Wetware is critical : Software is knowledge and understanding PDP-8 on an FPGA • PDP-8 Architecture : The seminal low-end micro • Enabling technologies : FPGA, VHDL & VITAL, JTAG • Design description : uC, Blinkenlites, Custom JTAG, IDE Emeritus Solutions’ Expertise • Technical Consultancy • System Development and Verification • Digital Signal Processing : Algorithms and Mechanisation • Underwater Acoustics : Algorithms, Analysis and Materiel • Navigation Solutions : Algorithms and Analysis • Computer System and Software Tools © Emeritus Solutions Ltd, 2008 Emeritus Solutions Ltd System and Software Obsolescence Intellectual property (IP) is fundamental to the effective management of system and software obsolescence.

The Computer History Simulation Project
The Computer History Simulation Project The Computer History Simulation Project The Computer History Simulation Project is a loose Internet-based collective of people interested in restoring historically significant computer hardware and software systems by simulation. The goal of the project is to create highly portable system simulators and to publish them as freeware on the Internet, with freely available copies of significant or representative software. Simulators SIMH is a highly portable, multi-system simulator. ● Download the latest sources for SIMH (V3.5-1 updated 15-Oct-2005 - see change log). ● Download a zip file containing Windows executables for all the SIMH simulators. The VAX and PDP-11 are compiled without Ethernet support. Versions with Ethernet support are available here. If you download the executables, you should download the source archive as well, as it contains the documentation and other supporting files. ● If your host system is Alpha/VMS, and you want Ethernet support, you need to download the VMS Pcap library and execlet here. SIMH implements simulators for: ● Data General Nova, Eclipse ● Digital Equipment Corporation PDP-1, PDP-4, PDP-7, PDP-8, PDP-9, PDP-10, PDP-11, PDP- 15, VAX ● GRI Corporation GRI-909 ● IBM 1401, 1620, 1130, System 3 ● Interdata (Perkin-Elmer) 16b and 32b systems ● Hewlett-Packard 2116, 2100, 21MX ● Honeywell H316/H516 ● MITS Altair 8800, with both 8080 and Z80 ● Royal-Mcbee LGP-30, LGP-21 ● Scientific Data Systems SDS 940 Also available is a collection of tools for manipulating simulator file formats and for cross- assembling code for the PDP-1, PDP-7, PDP-8, and PDP-11. -
