CoCoPilot DELUXE: CoCoWiFi + SirSound + DriveWire + CoCoPi + More


  • 2019-05-10: Added a link to CoCoWiFi article, and uppercased DELUXE.

TLDNR: See the video at the end.

In 2015, Sub-Etha Software rocked the retro world with the announcement of CoCoPilot. (And by “announced” I mean “posted a blog article about how to install DriveWire on a Raspberry Pi. And by “rocked” I mean “posted a block article about how to install DriveWire on a Raspberry Pi.)

In 2017, Sub-Etha Software raised the bar again by announcing SirSound, the serial port multi-voice sound “card” for the CoCo. (And by “raised the bar” I mean “posted another blog article”.)

In early 2018, Sub-Etha Software released details on CoCoWiFi, and showed you how to build your own for under $10 instead of waiting for Sub-Etha Software to actually manufacture them. (And by “released details” I mean “posted yet another blog article”.)

In late 2018, Sub-Etha Software shocked the CoCo Community with the proposal to end all proposals: PreciousPak. (And by “shocked” I mean “posted a block article about something I think would be really cool but don’t have the hardware skills necessary to make happen so I hope someone else will do the work for me, please and thank you”.)

And now, in 2019, Sub-Etha Software is proud to announce…


CoCoPilot DELUXE is the result of dozens of man-minutes of thought on the subject of “what should I do with all the Raspberry Pi stuff I have on my desk?”

Much like how PreciousPak solves all our problems when it came to CoCo cartridge add-ons, CoCoPilot DELUXE strives to solve all our problems when it comes to CoCo bitbanger serial port add-ons. (And by “solves all our problems” I mean “wouldn’t this be fun to play with?”)

With CoCoPilot DELUXE plugged in to your CoCo’s built-in Serial I/O port, you will have:

  • WiFi Modem – Use any existing CoCo terminal program, and be able to telnet, ftp, etc. to internet servers just as easily as you used to call in to dial-up BBSes in the 1980s.
  • SirSound – Use the simple BASIC “PLAY” command strings that you already know and love, except add a “#-2,” and change PLAY to PRINT, and then you can play multi-voice background music while your BASIC program does other things.
  • DriveWire Server – Use NitrOS-9, SDC-DOS or the special DriveWire version of HDB-DOS to access virtual floppies over the serial port. Under NitrOS-9, you also have access to other DriveWire features such as virtual printing, virtual MIDI, and virtual reality. Except maybe not that last one.
  • Print to PDF – Print from any CoCo program (including graphics programs such as CoCoMax, ColorMax, Max-10 and Max Headroom) and have the dot matrix output be rendered as a PDF file you can then print on a modem printer. It can even print the old green bars and fake tear-off strips with the holes in it, just like the olden days!
  • CoCoPi Emulation – This portable device can also be expanded with an option USB keyboard, USB mouse, and HDMI monitor to act as a virtual CoCo running various Color Computer emulation programs.
  • …and more!

In this list, there are a few “new” things we can’t currently do. Printing from CoCoMAX 3, Tandy Home Publisher or any other graphical print software is not currently possible (is it?). A new layer would be written to interpret common printer “driver” codes (Tandy, IBM, Epson, etc.) — including color — and render the incoming data to an image that represents all the dots the printer would have printed. (Heck, we could even emulate the old plotter printer thing.)

SirSound could work the same as the hardware SirSound (API compatibility), but could be expanded to do more voices, and use better sounds. The Pi has simple libraries that can product multi-voice music.

WiFi Modem would be similar to the CoCoWiFi (Zimodem) project, but the “AT” Hayes Smartmodem commands would be different since we’d just use one of the many “serial to network” programs/scripts readily available.

All we need is a bunch of software, an RS-232 interface for the Pi, and some switches to select which mode you want the CoCoPilot DELUXE to be in.
