Re: Help with MacMAME (Tony Schountz)

OK, I have it sorted out. I found my 6309 coco3.rom with Disk Extended
Basic and it's booting the OS-9 Level II OEM disk image just fine. I tried
a couple of other boot images I had used before with Jeff
Vavasour's emulator but they do not work. I suspect I'll need to build
fresh boot images.

Thanks for the help - it got me where I needed to go!
