Front Panel Interface Firmware Update 1.1

Postby AltairClone » October 11th, 2020, 12:29 pm

I have released an update to the firmware for the Altair 8800c front panel interface board. Firmware version 1.1 is available here: ... air_8800c/

In version 1.1, the inject code for the two Intel hex file loaders has been updated to stay and execute at the address specified on the front panel switches instead of relocating itself to high memory when executed. With the previous version, you could not load a hex file into high memory even if you specified that that loader be placed in low memory.

Thanks, Mike! I don't need this new ability at the moment but it's nice to have it there when I do. The update went smoothly with no problems and now memory location 0 shows the new version number when the FP parameters locations are loaded into RAM.
