[TUHS] DCJ-11 processor with 20k FPGA

[TUHS] DCJ-11 processor with 20k FPGA

[Jason Stevens via TUHS]

I assume people have seen this?

https://github.com/ryomuk/TangNanoDCJ11MEM/tree/main


It's capable of running Unix v1 & some limited amount of v6 among other
things.   The FPGA in question the Tang Nano 20k is sub 30GBP delivered from
AliExpress.

Kind of neat to combine a real processor with a simple FPGA implementation
of the hardware.

I just had a look at it, but he doesn't show the code, which runs on the 
TangNano?

Hello,

Would that be it? 
https://github.com/ryomuk/TangNanoDCJ11MEM/tree/main/applications/unix-v1/TangNanoDCJ11MEM_project.20240729.beta/src

I have not found synthesis toolchain info. All the doc is written in 
japanese with no way to get proper english info except via ai translation.
