Kettled twice. Extra chewy, extra trustworthy.
Summary
A developer has successfully ported the ao486 MiSTer PC core to the Sipeed Tang Console 138K FPGA, creating 486Tang v0.1. This represents the first known port of ao486 to a non-Altera FPGA. The project involved significant architectural changes including switching to SDRAM for main memory and adapting the core to work with the Tang Console's different FPGA architecture.
