    Default rx01 emulator on github

    I had a pretty good week debugging my latest project. It's a RX01 emulator (sort of). It uses a standard RXV11 (M7946) interface and emulates 2 drives of 32768 blocks each.
    I can't take credit for the idea. Years ago I found RX11emu by Pete McCollum. I can't find it online anymore but I had archived a copy. RX11emu used a custom board and ran on a PC. I use the standard interface and run on a small custom PCB. Pete supported the same 16meg drives.

    it's available at https://github.com/joelang/rxem

    I have a custom handler for RT-11. tested on V5.03. Two 16meg drives on RT-11 is pretty generous. The speed is not too bad. It's not MSCP/DMA speed. Think TU-58 with zero seek time and 1.5 megabaud connection.

    Neat!

    After I get through my s100 projects I will play with this.
