COMX is a new emulator of the COMX-35 computers for Windows.

My emulator emulates the fairly unkown COMX-35 computer from the early 80s and also some other 1802 based machines like the Cosmac Elf, Studio II and Cidelsa.

Current version is 0.8.3 and I´m still working on improvements, mainly on additional HW support for the COMX like disk support, printer and other.

Marcel van Tongeren is creating a COMX emulator in the C++ language based on the COSMAC ELF emulator written by Mike Riley, with some help of me and Barend Scholtus. Sound is working now (MUSIC, TONE and NOISE command) and even known bugs from the past are reproducible. Speed can also be adjusted now so you can boost the speed of the COMX beyond 2.813 MHz ! The emulator can be downloaded here or by clicking on one of the COMX-screens above.

Also PLOAD, PSAVE and even a Turbo version are build in already at this moment. That way we can load and save programs that are originally stored on cassette tapes just like in the good old days. On the Games and Programs pages you can download .COMX-files with all kinds of software made for the COMX. With version v0.83 of the emulator you can load them not by using the PLOAD command, but with the ‘Memory LOAD’ button. I will keep you informed when there is more information available or a new version of the program so keep checking this page…

With the files that will be made of other hardware ROM’s it may be possible in the near future to add more functionality to the emulator like disk drive support and printing. For the disk drive controller, expansion box and RAM Card there are already ROM’s available. We are working very hard on these options and will keep you informed ! When you have an expansion card in your possession that is not build-in yet, like the voice synthesizer or printer card, please contact me.

By the way, in the emulator are also modes and ROM’s available for the Elf, Studio II and Cidelsa systems !
