I programmed it to look like an RL02 and got it to boot rt-11 on my 11/44. But I didn't like some of the hacks I had to do and so re-did the cpld and then ran out of space. Always the way. I plan to have another go at it this spring/summer. I think the idea has merit. I think I should have used an fpga instead of a cpld however but I was being cheap. It's nice to put the entire bus transaction engine with dma support inside the cpld. Originally I had the cpu doing everything but found it was hard to keep bus timeouts from happening. The last working version has several state machines which minimize the cpu work. It can look like rom and can be a bus master so I use it to goose a copy of the boot loader into ram which makes life easier. like everyone, I took on some huge projects over the last 1.5 years and all my fun work was on hold. But those days appear to be over for a while :-| so my back room will be a little warmer. -brad
