  • Virtual MC-10, an emulator for the Radio Shack TRS-80 Micro Color Computer MC-10 (Version 0.69a September 20, 2004)

  • Kutenkamen - Roger Torre. This is a short adventure featuring 25 locations. This adventure will run on an MC-10 (and a Color Computer).
  • Haunted - Roger Torre. A Haunted House adventure. It's harder than Kutenkamen.
  • Solitaire - Roger Torre. Solitaire game for the MC-10 (and for the Coco).
  • Playback. A "repeat-the-pattern" game for either the MC-10 or the Coco. Similar to "Simon".
  • Sea Battle - 'Bob'. This is a battleship type program originally written for the MC-10. It is fairly well self-explanatory, have fun.
  • MC10 CW - Dave Satterfield WB7VET. Got an MC-10 lying around gathering dust? Here's a little one for the would be Ham. It will give three forms of code practice. Also runs on COCOs 1,2,3.
  • CSAVEM - Richard Stroud. Documentation and Program for a 'CSAVEM' utility for the MC-10. Also includes an assembly source listing. This allows you to save M/L programs.
  • Cass Copy - Richard Stroud. A simple tape-to-tape cassette copying program for MC-10 backups
  • Asteroids 64 - Rogelio Perea. Trek thru the Stars with the MC-10. A 64 by 64 graphics grid on the MC-10 from BASIC?... Yes!!. This game has them and it does make a difference between the 64x32 grid "supported" by BASIC... well that's what THEY told us. Along the program there's an explanation as to why things happen.
  • Basic Commands - Richard Stroud. This is a listing of the MC-10 BASIC commands and functions, along with their decimal and hexadecimal entry points. Also listed are the tokens used by the interpreter to store the commands internally.
  • Hi Res Display - Will Snyder. A program to display high res pictures from the Trs-80 Color Computer on the MC-10.
  • MC-10 Mini Technical Addendum - Rogelio Perea. This short text file includes some pointers on POKEs to enhance the operation of BASIC programs in the MC-10. Included are some hints to use for the printer, the keyboard and screen. This is one of the few files I have seen regarding Technical Info for the MC-10. It has been a long while since this micro saw the light of day but the info here should appeal to all die-hard CoCo fanatics.
  • Disassembler 03 - Richard Stroud. A 6803 disassembler written in MC-10 BASIC.
  • Opcodes - James Denney. This prints an opcode table for the 6803 microprocessor. No frills, just mnemonic, hex and decimal. Thanks to Rich Stroud for "DISA03.MC" from which this is derived.
  • MC10 Info - John Cullings. This text file contains information for the serious MC-10 programmer. It lists books, magazine articles, and software of interest to the MC-10 machine language programmer. A good communications program and monitor program is listed.
  • Lunar position for the MC-10 and CoCo - Paul J. Burke. Computes the position of the Moon for any recent date. Lists the position in RA and Dec.
  • MC10Convertor **NOTE This program runs on the Coco only. It allows you to load a Coco Basic program, then convert it and CSAVE it out as an MC10 Basic program. It is a binary file. Addresses are: &H3000, &H30CC, &H305C
  • COLOR TO MC10 CONVERTER -- MC10 TO COLOR CONVERTER. These two are written in Basic by William Barden Jr. Merge the program to convert and save it. Documentation is here. A list of tokens is on the Miscellaneous page.
  • Cram - PETER PAPLASKAS (HOT CoCo November 1983). This simple, yet addicting game for the micro CoCo is guaranteed to give hours of enjoyment. A conversion from an article by Hardin Brothers, which appeared in the August 1982 issue of 80 Micro, p. 234. I thought this would be an excellent candidate for the MC-10, because it uses only 1,531 bytes of RAM. The game is quite simple; hit any key to make the moving line turn at right angles, so as to avoid the border and the line itself. Your score is based on how many right turns you complete. Also, another score is recorded for previous highs. The game ends when you either hit the surrounding border or if you run into the line itself. You will then hear a series of tones that end the game. The REM statements explain fully the operation of the program.

  • Block Drop
  • Dragon Castles

These next are from "TRS-80 Color Computer & MC-10 Programs", Cat 26-3195, by William Barden Jr. You'll need the book to use these.

The next two are from "How to use your Radio Shack Printer", Cat 26-1242 by William Barden Jr.  The book is a help here also.

You can find these books at times on eBay, or on Amazon.
