I'm working on that. My real job just keeps
getting in the way. I've
gotten it to almost boot rt-11 from a fake rl02. There's still
debugging to be done but the basic concept is working. Basically it's a
small cpld and a tiny arm cpu. It can be a bus master, generate
interupts, dma, whatever. I'm reading the disk image from CF card but
it also has a usb function port (and a serial port).
I have a question about this approach. Is CF card good enough to be written
thousands of times, or even more? I am thinking about making a substitute
MFM HD with DSP and CF card. But I worry about the CF's ability to survive
many writes.

I hope to finish getting rt11 up in the next month or two. It's been
hanging off an extender card in an 11/44 (on it's
side) for a few months
now...
