Project Oberon http://www.projectoberon.com modified to use SDRAM instead of static RAM
Static RAM is old technology in FPGA world, and 1MB 32bit SRAM is hard to find on FPGA dev boards.
I upgraded this great project with a cache memory, which is able to interface SDRAM and DDRAM.
I uploaded the project archives for FleaFpga and for PapilioPro.
I will also provide DE2-115 and Nexys4 versions.
