OS-9/68000 has a device driver for RAMdisk (editorial: rather a bogus use of memory! the way OS-9 works, cache (with write-through, for robustness) or something that would benefit all disks on the system would be much better for performance!). That would be a good starting point for a 6809 version, especially if you could deal a Level Two version for the 68000, which would have to deal with the sorts of things a 6809 RAMdisk would (i.e. making sure you're in the right address space at the right time). Ask Microware about it. Alternative suggestions for the extra RAM: put video and font memory in it for use with O-Pak, so it won't eat the memory where OS-9 lives. (I guess that suggestion is better pointed at Frank Hogg, but then he's pushing FLEX <emulate Mr. Creosote here> for the CoCo.) James Jones
