[Coco] Latest Release of the VCC Color Computer 3 Emulator

[Bill Pierce]

Robert, the 3rd & 4th hdbdor roms (hdbdw3bck.rom) has the hi speed poke turned off.
HDBDOS for Coco 3 inits the high speed poke and if you turn it off, it will come back on with the first disk read. If you are trying to play rsdos games, they may be too fast and be unplayable. These alternative roms are actually the coco 2 roms (no hi speed poke) as the only difference between the 2 & 3 is dw4 baud rate and hi speed. Since the becker port uses tcp/ip, there is no baud rate (straight data flow as fast as possible)... So, they are the same except hi speed allowing you to 'stay' in slow speed.

You also don't have any floppies or a .vhd mounted on VCC.RGBDOS should be used with VCC if you want to mount a .vhd image directly in VCC or use floppies on VCC. With this ROM, and it is Not selected as an "External ROM Image", you will have access to 256, single sided, 35-track, Basic Disks on the .vhd. You can boot into NitrOS-9 on the .vhd via a boot disk that is one of the 256 on the .vhd.If you want access to disks on Drivewire, you must tell VCC to use an "External ROM Image" and that image should be one of two, hdbdw3bc3.rom or hdbdw3bc3 w-offset 5A000.rom. If you intend to boot NitrOS-9 from the .vhd mounted in Drivewire, you want the one with the $5A000 offset.The most recent VCC package also contains the hdbdw3bck.rom which says it is for a Coco2. I don't know why that is in the package as VCC does not emulate a Coco2.Once VCC is set correctly, the settings will be remembered. You don't need to repeat the settings each time you start VCC.Robert-- Coco mailing listCoco at maltedmedia.comhttps://pairlist5.pair.net/mailman/listinfo/coco
