…p_machine to print machine name and device list. Change printing of map so that it only prints on interesting boundaries (basically, when anything changes). Add info command that calls dump_machine. Update documentation accordingly. Tweak serial.c to stop eon2 from core-dumping.
Changed the image file reader to auto-detect the file type (currently supports hex and s19). Reworked the image file readers to cope with both Unix and DOS line endings and to do a bit more checking (which also reduced compilation warnings).
…age: map ioexpand over a ROM, use one slot for I/O and map the remaining slots to the "underlying" ROM by supplying an offset when mapping each slot.
…fault() to fault() and move it to machine.c. Revise README accordingly.
turn off echo on i/o available to target system; target system is now responsible for echo.
…outines to fix-up keyboard codes for target machines that expect a DOS-like 0x0d as the line ending.

…X to boot in emulation.
that is invoked (if it exists) by the previously unimplemented du command.
currently start up properly using .hex files as they load over the I/O and corrupt it. Works OK with .bin files. Problem with .hex files will be fixed by defining a "startup" phase when they are loaded. Lots of nasty hacks in this code at the moment; need to think through some proper fixes to the problems exposed here.
Always exit with success - for now. Need this so that I can terminate the simulator on reaching a cycle limit. Want a cleaner way of doing this in order to run the emulator in a scripted loop for test4gcc6809.

enabled; and vice-versa. Currently do not support enable of perodic IRQ and FIRQ interrupts at the same time.
with the read-modify-write behaviour of the CLR instruction.. but only when used with extended addressing.
do ASCII dump like this: x/32c 0x100
level1 kernel time OK.
Rx interrupts when the FIFO is non-empty. Has only undergone brief testing but seems to work well enough not to break polled code and to allow NITROS9 L2 to boot to the shell, and FUZIX to continue to boot.
…t interrupts in the mc09 machine. Scarily clean now! FUZIX and NITROS9 L1 (both of which use timer and UART interrupts) both boot and appear to work correctly.
interrupts were enabled, regardless of whether a character was available. Now, only indicate an Rx interrupt when interrupts are enabled AND the Rx FIFO is non-empty.

Hi,
I was in the marked for a 6809 emulator and, resisting the temptation to start one from scratch I thought that I would try to build on the work you have done on exec09. I realise that you have not worked on this project for ages, but I wanted to check and see whether you are interested in pulling any of my changes into your repository. If you are, I will work to maintain the existing code structure etc. If not, I'll be a bit more relaxed about what I change.
regards,
Neal
