Getting Started with DriveWire

2025-08-28T03:50:38Z

MarkO: Fixed Old Links to Google for DriveWire 4, added OpenJDK 17 to DriveWire 4 Repack and Changed the Version Number of pyDriveWire Manual

{{NavDriveWire}}
A brief history and information guide to both DriveWire3 and DriveWire4 including separate installation guides for DW3 & DW4
== Forward ==

DriveWire is a server side application used in Windows, MacOS (and Linux for DriveWire 4) to provide a disk emulation server for the Tandy/TRS-80 Color Computer series of home computers manufactured during the '80s & '90s.

DriveWire allows the mounting of virtual disk images on a PC style computer, to provide floppy disk emulation. Real floppy disk hardware is becoming difficult to find these days, so applications like DriveWire provide CoCo users a much needed storage method for enjoying their Color Computers again. This Wiki page will attempt to provide the basic information needed to configure a DriveWire system for your CoCo.

Out of respect for software authors, this Wiki page will not host or directly link to any files - links will only take you to the webpages where these files already exist, and can be downloaded from.

Also, DriveWire 4 is a 100% drop in replacement for DriveWire 3. DriveWire 4 simply (or not so simply) adds far more capability to an already excellent application.

One more thing to keep in mind - DriveWire 3 and 4 can be used as a floppy disk emulator. However, there are some software packages that simply will not run when using floppy emulation. This is due to the author creating their own disk access routines, instead of using the RS-DOS DSKCON routines or in some cases, using a ROM/RAM copy routine that wipes Coco client side HDBDOS/DW3DOS from memory when they're running from disk or cassette. Until a successful hardware emulator is created that can accurately emulate the WD1773, then we are stuck with this situation.

----

== DriveWire Server ==

There are a number of DriveWire servers available. Your choice of server largely depends on the features you want and the requirements of your server operating system.

=== DriveWire 3 ===

DriveWire 3 acted solely as a virtual disk server for a CoCo. Written by Boisy Pitre and sold thru [http://www.cloud9tech.com Cloud9], DriveWire3 is a great tool for those needing just a virtual disk server. The DriveWire 3 PC server software can be freely downloaded [http://www.cloud9tech.com/Cloud-9/Hardware/DriveWire3.html Here].

}}

DriveWire 4 is a Java version of DriveWire moved to an Open Source project, and has similar functionality to DriveWire 3. However, the developers have added many other features including: mounting of Internet based disk images, TCP, web server, MIDI control, print to a PC printer (emulates Epson MX-80 from CoCo side, compatible with most Epson and generic printer drivers for the CoCo) and many more.

To use DriveWire 4, you'll need Java version 8 - as DriveWire 4 is written in Java, it is OS agnostic; meaning it should run on anything that runs a Java 8 VM, including a Raspberry Pi running Linux. You can get a [http://www.java.com/en/download/manual.jsp JavaVM (here)] for most any type of popular operating system. However, if your operating system requires a more recent version of Java, you may need to try one of the other DriveWire server options.

You get get the most recent version or DriveWire 4 by visiting the [https://sourceforge.net/projects/drivewireserver/files/ DriveWire4 distribution site] and following the links. As you'll soon see, DriveWire 4 supports several computing platforms including all versions of the CoCo. The documentation Wiki for DW4 can be found here: [http://sourceforge.net/apps/mediawiki/drivewireserver/index.php?title=Main_Page DW4 Wiki].

PyDriveWire is a nearly complete DriveWire4 Server written in Python. The goal is to eventually implement all of the features available. The server also implements additional features that are not available in DriveWire4.

PyDriveWire also has support for the EmCee Protocol for use with MCX Basic on the TRS-80 MC-10.

DriveWire 4 and EmCee Procotols can be used simultaneously on the server without reconfiguration.

Once you have downloaded the DriveWire software and connected the CoCo to your PC with the correct cable, you'll need to boot the CoCo with an HDB-DOS ROM image. This can be done with a ROM Pak with an HDB-DOS EPROM from Cloud9 (or someone else); loading thru the cassette port (from either a real cassette player or as a .wav file from a PC), an EPROM placed in a floppy controller or even an HDB-DOS ROM loaded from a .BIN file.

However, the developers have added many other features including: mounting of Internet based disk images, TCP, web server, MIDI control, print to a PC printer (emulates Epson MX-80 from CoCo side, compatible with most Epson and generic printer drivers for the CoCo) and many more.

To use DriveWire 4, you'll need Java version 8 - as DriveWire 4 is written in Java, it is OS agnostic; meaning it should run on anything that runs a Java 8 VM, including a Raspberry Pi running Linux. You can get a [http://www.java.com/en/download/manual.jsp JavaVM (here)] for most any type of popular operating system. However, if your operating system requires a more recent version of Java, you may need to try one of the other DriveWire server options.

You get get the most recent version or DriveWire 4 by visiting the [https://sites.google.com/site/drivewire4/ DriveWire4 distribution site] and following the links. As you'll soon see, DriveWire 4 supports several computing platforms including all versions of the CoCo.

A brief history and information guide to both DriveWire3 and DriveWire4 including separate installation guides for DW3 & DW4
== Forward ==

DriveWire is a server side application used in Windows, MacOS (and Linux for DriveWire 4) to provide a disk emulation server for the Tandy/TRS-80 Color Computer series of home computers manufactured during the '80s & '90s.

DriveWire allows the mounting of virtual disk images on a PC style computer, to provide floppy disk emulation. Real floppy disk hardware is becoming difficult to find these days, so applications like DriveWire provide CoCo users a much needed storage method for enjoying their Color Computers again. This Wiki page will attempt to provide the basic information needed to configure a DriveWire system for your CoCo.

Out of respect for software authors, this Wiki page will not host or directly link to any files - links will only take you to the webpages where these files already exist, and can be downloaded from.

Also, DriveWire 4 is a 100% drop in replacement for DriveWire 3. DriveWire 4 simply (or not so simply) adds far more capability to an already excellent application.

One more thing to keep in mind - DriveWire 3 and 4 can be used as a floppy disk emulator. However, there are some software packages that simply will not run when using floppy emulation. This is due to the author creating their own disk access routines, instead of using the RS-DOS DSKCON routines or in some cases, using a ROM/RAM copy routine that wipes Coco client side HDBDOS/DW3DOS from memory when they're running from disk or cassette. Until a successful hardware emulator is created that can accurately emulate the WD1773, then we are stuck with this situation.

== DriveWire Server ==

DriveWire 4 is a Java version of DriveWire moved to an Open Source project, and has similar functionality to DriveWire 3. However, the developers have added many other features including: mounting of Internet based disk images, TCP, web server, MIDI control, print to a PC printer (emulates Epson MX-80 from CoCo side, compatible with most Epson and generic printer drivers for the CoCo) and many more.

To use DriveWire 4, you'll need Java version 8 - as DriveWire 4 is written in Java, it is OS agnostic; meaning it should run on anything that runs a Java 8 VM, including a Raspberry Pi running Linux. You can get a [http://www.java.com/en/download/manual.jsp JavaVM (here)] for most any type of popular operating system. However, if your operating system requires a more recent version of Java, you may need to try one of the other DriveWire server options.

You get get the most recent version or DriveWire 4 by visiting the [https://sites.google.com/site/drivewire4/ DriveWire4 distribution site] and following the links. As you'll soon see, DriveWire 4 supports several computing platforms including all versions of the CoCo. The documentation Wiki for DW4 can be found here: [http://sourceforge.net/apps/mediawiki/drivewireserver/index.php?title=Main_Page DW4 Wiki].

PyDriveWire is a nearly complete DriveWire4 Server written in Python. The goal is to eventually implement all of the features available. The server also implements additional features that are not available in DriveWire4.

PyDriveWire also has support for the EmCee Protocol for use with MCX Basic on the TRS-80 MC-10.

DriveWire 4 and EmCee Procotols can be used simultaneously on the server without reconfiguration.

Once you have downloaded the DriveWire software and connected the CoCo to your PC with the correct cable, you'll need to boot the CoCo with an HDB-DOS ROM image. This can be done with a ROM Pak with an HDB-DOS EPROM from Cloud9 (or someone else); loading thru the cassette port (from either a real cassette player or as a .wav file from a PC), an EPROM placed in a floppy controller or even an HDB-DOS ROM loaded from a .BIN file.

== Description ==

The CoCo SDC is a Color Computer Floppy Disk Emulator running [[SDC-DOS]] (effectively a floppy drive controller replacement), ready for [[Drivewire]] server communication. It was designed by [[Darren Atkinson]].

Instead of hooking up old, hard to find floppy drives or cassette recorders, it gives direct access to floppy disk, cassette and ROMpak images stored on modern SDHC card storage. This is implemented by SDC-DOS additional commands to mount disk image files on the SD card, program the Flash and execute ROM images contained in the Flash. DriveWire disk support is also included in SDC-DOS.

Provided your system has a [[Multi-Pak]], you can connect a real floppy interface and the CoCo SDC at the same time, then backup physical floppies to disk images on an SD card. Copy protected disks can be backed up using tools like Carl England's [[Defeater]]. It is also useful to backup software loaded from cassettes.

The CoCo SDC also provides 128K of Flash memory which is divided into 8 banks of 16K so users can program their favorite ROM or alternative OS as well. SDC-DOS and DECB reside in banks 0 and 1, respectfully, when shipped.

Based on an Atmega micro-controller, the CoCo SDC emulates the Western Digital 1774 floppy controller chip and as such is basically 100% compatible with any CoCo software, including copy protected disks. CoCo floppy disk replacement devices and software have one major shortcoming – the inability to use software in which the author wrote his or her own floppy disk access routines. All versions Drivewire and the SuperIDE; CoCoNet and the Micro SD Pak, Bluetooth Pak and RS-232 Pak all suffer from this problem. The CoCo SDC aims at aleviating this problem.

=== The CoCo SDC case ===

The CoCo SDC was designed to fit into a FD-501 or 502 case, as shown below.

Deluxe RS-232 Program Pak

MarkO: Changed Link to SockMaster's Page because was not loading.. e.g "www" to "users"...

{{NavHardware}}
[[File:Deluxe RS232.jpg|thumb|Deluxe RS232 (26-2226)]]
Copy of [http://users.axess.com/twilight/sock/rs232pak.html Sock Master's] & [http://users.axess.com/twilight/sock/rs232.html Sock Master's RS232 Pak Stuff.]

RS-232 Pak Data Sheet

The heart of the Deluxe RS-232 Pak is the Synertek 6551 ACIA. It has an on-chip baud rate generator, programmable interrupts and status register for ease of operation, false start bit detection, and echo mode
<h2>Memory Address</h2>
This ACIA board is memory mapped to addresses $FF68 (65384) to $FF6B (65387).

The 6551 uses 4 memory addresses for the following functions:
{| cellpadding=3 cellspacing=0 border=2
! Address
! Write
! Read
|-
| FF68
| Transmit data<br>Register
| Received data<br>Register
|-
| FF69
| Soft Reset
| Status Register
|-
| FF6A
| COLSPAN=2 ALIGN=middle | Command Register
|-
| FF6B
| COLSPAN=2 ALIGN=middle | Control Register
|}<br>
This table shows that only the Command and Control registers are bidirectional. The Soft Reset operation
clears the 6551 internal registers but does not cause any data transfer. Therefore, the data written is a "don't
care." A RES* from the bus will clear all registers in the 6551 while a Soft Reset will disable interrupts and
transmitter, turn off echo mode, and clear the Overrun Error flag only.

The following shows the Status, Command, and Control Register and gives programming examples for each:
<h2>Status Register ($FF69)</h2>
The Status Register is used to indicate to the processor the status of various SY6551 functions.

<h2>Increase Hi-Speed Performance</h2>
Notes about adding hardware handshaking and other modifications to the CoCo's RS-232 to increase hi-speed performance

<hr>
Sock Master's notes about hardware handshaking and other modifications to the
CoCo's 6551 based RS-232c Pak.
<hr>

I've been running a BBS on my CoCo for the last 11 years or so. I'm usually
a bit behind on the technology side compared to most other BBSes, but many
people usually say that it makes the board more interesting. When I finally
got myself a 14.4Kbps modem for the BBS a year ago, I decided to simply run my
RS-232 at the maximum rate (19200 baud) and leave it locked there. No matter
what baud someone called in at, the flow control lines of the RS-232 are
supposed to keep my BBS from sending out too much data to low speed callers.
Well, it turns out that that is technically correct, but the 6551 has a *lousy*
way of dealing with CTS line changes. Every time the modem would raise
the CTS, the 6551 would stop dead in it's tracks - right in the middle of
sending a byte! For low speed callers, that meant every 200th byte or so was
truncated and percieved as trash.

I couldn't think of a very elegant solution to that problem, but for the
sake of my BBS, I solved it in the easiest way I could. I removed the CTS
signal (pin 9 on the 6551 chip) from the 6551 altogether and rewired it to the
cassette input (pin 4 on cassette port) with a 22K Ohm resistor. I then forced
the 6551 to always think the modem is ready by grounding the CTS on the chip
(Solder a wire from pin 9 to pin 1 on the 6551). I used the cassette port
because it's a free input port that's generally unused by everyone. This
works, but you have to patch your RS-232 driver to accomodate it. My new
driver simply checks the state of the cassette port before deciding if it
should wait to transmit the next byte or not. But, even with unaltered driver
routines the 6551 will no longer destroy outgoing data and no problems will
arise except in the case of the computer sending out more than 1.5K or 2K ahead
of the modem, which is fairly unlikely. This is simple enough not to need a
diagram, so I didn't include this in my drawing. The drawing is too crammed
as it is already.

Now for what IS in the diagram: The other problem with putting a high-speed
modem on my BBS is a little less important, but fixing it makes everything
much easier. With this modification the CPU gets less bogged down, the RS-232
driver becomes easier to write, and the BBS *never* misses any incoming data.
Normally, the 6551 simply has no way of telling my modem when it's data buffer
is full. If someone called my BBS at a high baud rate and tried uploading a
text file, my driver simply didn't read the data fast enough to get it all
without missing bytes. Every time the disk drive went on, the CPU halts and the
6551 misses more data. In order not to miss data, the RS-232 driver would have
to immediately read data from the 6551 every time a byte came in. The
solution? I made a little circuit that sits on top of the 6551 chip (a 74ls32
and 74ls00) that generates a new RTS control signal. Since modern modems have
a data buffer, it would be really neat to unload a lot of work from the CoCo
and leave it for the modem to do. This hardware circuit simply creates a new
RTS line for the 6551. Every time the 6551 receives data, the circuit raises
the RTS line (which tells the modem to stop sending to the CoCo) until that
data is read by the software. If the driver reads the data at the full
incoming speed, there is no slowdown in throughput. If the driver goes on a
break, or the disk drive comes into use... whatever, the modem is told not to
send any more data to the 6551 until the 6551 is ready to recieve it!
Effectively, the circuit disallows the 6551 from missing any data. It also
places the job of buffering incoming data on the modem, and not the CoCo.
The CoCo doesn't have to keep reading the 6551 every time a byte comes in,
since it won't lose the data if it lets it wait. Now it can read the data
when it actually wants it. This speeds up my BBS quite a bit, I only read
from the 6551 when the BBS wants input from the user. If the user transmits
stuff while the BBS is calculating, loading, thinking, etc... the modem will
buffer it for me.

Note: I've recently been informed that the RTS modification has a side effect
when used with certain kinds of modems. It works wonderfully with my U.S.
Robotics 14.4 Sportster which has a 2K data buffer. But, it may function
inefficiently with other modems lacking data buffers. What happens is that when
the RTS coming from the the CoCo signals the modem that the 6551 is not ready to
receive data, these modems may pass along this signal to the HOST computer and
tell it to stop sending data until the CoCo is ready for more. (This happens
because the modem does not buffer incoming data, therefore cannot store it if
the CoCo is not ready to receive.) This extra step adds a delay between
incoming characters because the signal ends up travelling huge distances across
the phone line between each character.

I also rewired the line that goes to Carrier Detect (DCD pin 16 on 6551)
signal to go to the DSR (pin 17) on the 6551. Make sure to cut any lines that
previously went to the DSR pin on the 6551. Then, I wired the DCD (pin 16) on
the 6551 to ground (pin 1). This way I can still recieve data when there is no
carrier, but I can still be able to detect carrier status by checking the DSR
state. (This is not shown in the diagram either because it's as easy as cutting
two wires and rewiring two pins.)

Lastly, I did the silly thing of replacing the 1.842Mhz clock crystal on the
6551 with a 3.684Mhz one. This doubles all baud rates. The 6551 can now run
at 38400 bps! (Warning: Many terminal programs that use GIME timer interrupts
to drive the RS-232 will still sample the RS-232 at their old sampling rate
(half the new rate required) which effectively reduces your throughput or
causes lost data - So, this modification is not recommended unless you know
that your software is driven by the 6551 Interrupt line.)

These four modifications each serve a purpose, but you don't need to
attempt them all. Each particular modification will do it's job all by itself.
You can try getting started with the easy modifications to the DCD or CTS first
and then decide if you want to try the more serious hardware hacking of the RTS
modification. If you want just a particular function of the 6551 'fixed', then
you can do just that modification too. I have all four done to my RS-232, and
they work wonders for the operation of my BBS.
