https://www.opencores.org/ Open Cores Repository.
The Open Cores web site seems to be the central repository for a wide variety of computer peripheral designs and is definitely worth checking out. The Open Cores site has a link page to other resources, so I won't include them all here.
https://www.fpgacpu.org Jan Gray's Risc CPU Web Site
Jan Gray has a XR16 RISC CPU , GR000 RISC CPU and XSOC (System on a Chip). He also runs the FPGA CPU mailing list.
https://www.itee.uq.edu.au/~jwilliams/mblaze-uclinux/ John Williams MicroBlaze uCLinux Web Site.
John Williams is a Professor at the School of Information Technology and Electrical Engineering at the University of Queensland. He runs quite an active mailing list for implementing uCLinux on the Xilinx MicroBlaze soft-core processor.

Various FPGA projects for the hobbyist. Includes information for connecting devices such as LCD Displays and R/C Servos to FPGAs.
https://www.retromicro.com Doug Hodson's Web Page
Doug has implemented a few projects using the XESS XSA100 FPGA Board. Doug's project page has some examples of VGA video generators. The XSA is quite a nice little board with Flash memory and Dynamic RAM, although the XSA100 uses a smaller FPGA and access to static RAM conflicts with some of the I/O pins. The XSA100 uses a XC2S100 FPGA and can be purchased with the XStend prototyping motherboard. For more details check out https://www.xess.com . They have all the manuals on their web site. The XESS documentation is quite good.

Daniel Wallner's Soft Cores Web site is now on Open Cores with five synthesizable microprocessor cores: PPX16 (PIC16C55, PIC16F84), T80 (Z80), T51 (8051), T65 (6502) and AX8 (90S1200, 90S2313).

Green Mountains Computing Systems have a MC68HC11 VHDL core as well as VHDL tools and simulators. I tried compiling this core under the Xilinx ISE 4.1 Webpack software and it used 200% of the XC2S200 resource, so it is not an efficient design. Later versions of Xilinx ISE Webpack may be more efficient.
