DWLOAD EPROM - instant DriveWire

The DWLOAD EPROM extends the BASIC ROM with the powerful DWLOAD utility, the easiest and fastest way to load programs over DriveWire from your uDW or PC.

DWLOAD is the easiest way to get started with DriveWire. No DOS needed, this ROM modification recycles the old "DLOAD" command to turbo charge your Dragon 32 or 64. Load files from your uDW or other DriveWire server as easy and fast as it possibly can get. This EPROM replaces the BASIC PROM on the motherboard. 100% compatible with the original Dragon 32 BASIC ROM.

Ordering and shipping information

DWLOAD lets you download programs from a DriveWire server to your Dragon. Although the DWLOAD utility can be loaded from tape or disk to get started, it really shines when it is integrated in the BASIC ROM - the DWLOAD EPROM.

On your Dragon 64, simply replace one of BASIC ROMs on the motherboard. On your Dragon 32 a 28-pin to 24-pin adapter is needed (sold separately). Note that some rare motherboards might have the original ROM soldered - please check before ordering.

The DWLOAD program takes the place of the non-functional DLOAD BASIC command. Simply type for instance DLOAD"MYPROG" to load the program "MYPROG" from the uDW or other DriveWire server. Works with both BASIC and machine language programs. Use "DLOADN" to just load a program without running it.

At power-on, a program "AUTOLOAD.DWL" will be loaded and run if it exists on the server. This can be any kind of program, for instance your favorite game or a start-up menu. Autoloading can be disabled by holding the shift key.

The DWLOAD EPROM ships in a anti-static IC carrier tube to safely protect pins during shipping.

Recommended hardware

The uDW DriveWire microserver is a standalone, SD card based mass-storage solution for your Dragon. Put all your programs and files onto an SD card and access them on the Dragon as if it had a floppy drive or PC-based DriveWire server. Plugs into the printer port, no other cables or power supplies needed.

The DWLOAD command and modification of the Dragon 32 BASIC ROM was written by Tormod Volden. The adaption to the Dragon 64 BASIC ROM was done by Ken H. from the Dragon forums. Many loadable extensions ("dweebs") are written by Pere Serrat.

DWLOAD includes bit-banger routines from Darren Atkinson, and some parts are based on Boisy Pitre's DW3DOS utility.
