(22JAN2006) Links on this webpage updated.

(04MAR2005) A Univerisity in Japan has done PDP-11 and VAX-11/780 implementations

(06JAN2003) There is now a webpage on both commercial and hobbyist FPGA implementations of DEC Processors

The Processor Families

PDP-4
1. David G. Conroy's FPGA Replica of the PDP-4
PDP-8
1. David G. Conroy's FPGA Replica of the PDP-8
2. A page on Jon Andrew's FPGA implementation of the PDP-8
3. Andrew Grillet is working on another FPGA implementation of the PDP-8, and is planning to also provide a bus of some sort so boards can be plugged in (most likely not OMNIBUS from the sounds of things).
PDP-10
1. XKL, LLC's XKL-1 is built using FPGA's
2. Neil Franklin was working on a PDP-10 Clone Microprocessor in FPGA (he stopped working on it at the end of 2003).
3. David G. Conroy is working on a FPGA replica of the PDP-10, but currently there isn't a web page on it.
PDP-11
1. Mentec Inc. used FPGA's for their M1 and M11 Q-Bus processor boards, they have since switched to reselling emulation solutions to run their OS's on.
2. Quickware QED995 (Anyone have any info on this board?)
3. Strobe Data used FPGA's on thier Osprey Co-Processor boards (these boards fit in an ISA or PCI slot and act as a PDP-11).
4. Tokai University has implemented a PDP-11/10 and PDP-11/40 in FPGA. It includes an EIDE disk interface, and they have run Unix V6 on it.
VAX
1. Tokai University has announced that they have a VAX-11/780 FPGA implementation.
2. RT Logic is re-implementing VAX computer systems in FPGA for Hewlett Packard.
