Yes. The keyboard and mouse handlers are only about 70 lines of Oberon
(Input.Mod) and about 40 lines of Verilog code (MouseP.v and RISC5Top.v).
You can download the source code and detailed design documentation from

If you want Project Oberon with HDMI/DVI video you can get the 'Oberon
system on Pipistrello'

 

"The original oberon code is basically unchanged, the only major code
addition is a module that takes the signals that normally drive an analog
VGA monitor and convert it to DVI output via the HDMI connector."
