COMiX ROM

To take advantage of the High Speed Direct Connect COMiX commands on the COMiX-35 computer, a new FW ROM with the PSAVE & PLOAD High Speed Direct Connect routines is required.

The new High Speed Direct Connect ROM removes the following functionality:

• PSAVE for tape save
• PLOAD for tape load
• TOUT (never document by COMX and rather useless)

If you would like to retain the original tape functions on your COMiX computer for PSAVE, PLOAD & TOUT, we recommend that you take advantage of the bank switching feature on the COMiX computer and program your 32K ROM with one 16K bank with the original FW revisions and the second with the applicable HSDC FW. This will allow you to switch between tape and HSDC version by changing the "ROM Bank" Jumper on your COMiX computer (JP5).

Four FW versions of the High Speed Direct Connect ROM are available in the Firmware Files section. Choose the version that is applicable to your COMiX system. Note that PAL video is most commonly supported in Europe and NTSC video is most common in North America:

• COMiX NTSC ROM
• COMiX PAL ROM
• COMX NTSC ROM
• COMX PAL ROM

Note that the COMX ROMs are not tested on a real machine as it would mean (re)soldering the ROMs.
