Previous project developments based on DE0_Nano, DE10_Lite, BeMicro_CV or DE0_Nano are available on
my homepage: https://pdp11gy.com/rlstat1E.html
Note: It also works with the current Quartus version V23.1
SoC/HPS based RL01/RL02 disk emulator/reader/cloner/(writer), Altera Cyclone V FPGA with ARM Cortex-A9 (DE10-Nano) The operation of the RL02/RL01 emulator is best viewed with a VIDEO via YouTube, however in the first version from 2012, based on the DE1-Board. https://www.youtube.com/watch?v=0i3ypBU39as
All sources with environment setup are located in the zip-folder DE10_SoC_RL_emulator_V2_8.zip
With the new firmware version V2.8E it is also possible to clone a disk without a PDP-11 system.
The software runs completely on the DE10-Nano board and generates .dsk files for direct further
use with SIMH. The most important is the verilog module read_one_track.v, which is uploaded again.

For info: Another project, MFM disk emulator, also based on the DE10-Nano board is now also available:
https://github.com/pdp11gy/SoC-HPS-based-MFM-disk-emulator Furthermore, it is planned to bring both
interfaces together like in the overview.pdf dokument. This action has been suspended for the time being.
Maybe someone has the motivation and time to complete the project? A ready-made proposal with pictures can
be found in the file zusammen.pdf. It's written in German, but with google translator it shouldn't be a problem.
A full, ready for use configured SD-card-image for the DE10-Nano Board is also available.
