I load the kernel over DriveWire, of course :) It is ideal for such cross-development. I have a soft link in my DW4 folder pointing to the kernel in my build tree, and also AUTOLOAD.DWL points to a FUZIX bootloader dweeb (dwfuz) so when the Dragon powers on it starts FUZIX from my latest build autom...

The way the memory extension works is similar to my +32K board , just with bank selection added. When mapped in, the selected bank overlays $8000-$FEFF. The FUZIX dragon-nx32 port was written with such a design in mind. For other operating systems, it can surely be used as a RAM disk if someone writ...

William's instructions on his patch are quite precise, but yes it is not the easiest thing to build. I have pre-built packages for Debian/Ubuntu here: http://toolshed.sourceforge.net/gcc/

There is only as09 and cpp so far... Currently we build the kernel and all applications with gcc-6809 (and lwtools) so it is cross-dev. It is very easy to set up on a Debian or Ubuntu machine.

Are you planning on doing a batch of these boards? Sure! I would love to see more people developing on FUZIX for Dragon, and over time, even using it :) I have at the moment just a small number of boards at hand, and will prioritize anyone serious about getting their hands dirty with development, j...

An update on my latest adventures in FUZIX land. Since FUZIX is pretty disk heavy, with large binaries, even DriveWire is getting a bit slow. For example, launching a simple command like "ls" (like "dir" in os9) currently means loading 22 KB from disk for the command itself. Of course, "ls" could ne...

I will definitely be coming back to this, but as I said 2 (!) years ago, next year... Too many interesting things came up in between. However with the smaller fonts on the FUZIX graphics mode console, this has become more important again ;) Note also that "Zippster" on the CoCo list is working on a ...

(I replied in the other thread already, then found this.) The CoCo does not have an ACIA, so it uses bit-banging which has its disadvantages.

Hi Tony, the serial port on the CoCo1/2 is not implemented with an ACIA like the Dragon 64, but is a bit-banger interface on PIA1 (the same as the DriveWire adapters for Dragon). This means more work for the CPU, and probably why the program limits the speed to 1200 baud - although DriveWire has sho...

Is it the CoCO3FPGA being discussed on the CoCo mailing list? Or Roger Taylor's DE0 project that I have also seen mentioned? Or Mark's Pacedev.net / CooCoo project*?
