This post includes instruction to build your own adapter cable for the Dragon 32/64.
You can also buy tormod's ready made Drivewire adapter.
DriveWire with the Dragon Drivewire Adapter and HDB-DOS for Dragon provide:
- Virutal Disk drives up to 4GB in size
Access to remote filesystems (HTTP/FTP/WebDAV/SSH/CIFS/etc)
Virtual/telnet modem emulation
Printing via an emulated Epson FX80 dot matrix printer
A real time clock
MIDI using a built in flexible synthesizer or external devices
Dragon 32/64 with
1) Parallel to bit-banger adapter (see instructions below)
2) HDB-DOS for Dragon. Can be burned on EPROM to your dos controller or CLOADed from tape
A floppy disk controller is not required
1) Serial port (or USB to serial adapter)
2) Drivewire server 4.3.0 or higher https://sites.google.com/site/drivewire ... edirects=0
Dragon Drivewire Adapter
The Dragon 64's serial port is not compatible with Drivewire. You will need to build a Dragon parallel -> bit-banger adapter.
Darren A created this nice schematic to show you how-
You will also need an inverter to invert the signal going out from the Dragon to the PC.
The Dragon's BUSY (pin 20) and ACK (pin 19) inputs are connected to the same PIA pins as the CoCo's RxD and CD inputs respectively.
The STROBE output on the Dragon (pin 1) is connected to the same PIA pin as the CoCo's TxD output, but is also inverted.
Connections for a 74LS04 inverter:
GND (dragon pin 18) to 74LS04 pin 7.
+5V (dragon pin 4) to 74LS04 pin 14.
Data in (Dragon pin 1 ) to 74LS04 pin 1.
74LS04 pin 2 to level shifter RXD
There are plenty of sources for Max232 level shifters for under $5. Just search ebay for MAX232.
A 20pin IDC Flat Ribbon Cable for jtag will fit the Dragon's parallel port connector.
Connect your Dragon to the PC using the parallel to bitbanger adapter and a serial cable.
On your PC:
Install Drivewire 4.3
Run the config wizard and select CoCo2 / 56K
On your Dragon (August 2013 Update):
Thanks to tormod & retrocanada76 Drivewire can now be used with the Dragon's native roms.
No need to replace the Dragon's roms or switch to CoCo mode.
Run HDB-DOS for Dragon on the Dragon using a cassette quick-loader , or even better burn the HDB-DOS rom on EPROM and install it in your DOS controller (or any other cartridge).
