A friend has asked for help with some 68HC11 assembly code. The code was written for a DOS/Windows cross-assembler with an executable name of X68C11. Does anyone know if that assembler can still be found, or if there is a compatible assembler that exists?

Well, I found that the assembler does still exist. The original creator, 2500 AD software, was bought by Avocet, who has kept up the 68HC11 product line.

Have a look at this link that might point you in the direction to find the sources...I did see that there is a way to use the GNU's gcc toolchain to produce a cross-compiled binary...

Hope this helps, Best regards, Tom.

  • Man, that's some old stuff. Bunch of dead links, etc. so far, but I remain hopeful. The real problem is there's a pretty good chunk of source, and I sure as heck don't want to port it all if it's not completely necessary. – Harper Shelby Feb 08 '10 at 22:34
  • @Harper: check this out, maybe with cygwin and this...http://www.gnu.org/software/m68hc11/ – t0mm13b Feb 08 '10 at 22:52

I'm not sure about X68C11, but my University of Michigan - Dearborn curriculum required me to program a 68HC11 using a cross-assembler called AsmIDE, which you can download at http://support.technologicalarts.ca/docs/HC12-related/ThirdParty/AsmIDE/ . That seems to be the only link to it I can find on the Internet, since the developer died and his websites were all shut down. If you want to use C, the same guy wrote a handy GCC IDE called EmbeddedGNU available at http://www.evbplus.com/hcs12_9s12/EmbeddedGNU_hcs12.html .

    Disregard the "HC12-related" in the URL above -- AsmIDE is compatible with both the HC11 and HC12 instruction sets. – gpcz Feb 24 '11 at 23:17
