The amazing multi-processor 8-bit microcomputer, featuring Z80, 6502 and AVR processors. Built with CPLDs, CERBERUS 2100™ is fully programmable even with respect to its hardware, at the individual gate and flip-flop level.
I have an Agon2light, and recently received my Cerebrus 2100. I fought with keyboard issues for a few weeks, none of the keyboards that worked with Agon would work with Cerebrus. No powerup sequence on the keyboard lights.
I ordered another keyboard (from Agon Australia) just to be sure, and it didn't work either!
I was looking around at it again this morning, and discovered that if I plugged in the keyboard AFTER powering up the Cerebrus the blinkenlights appeared and the keyboard works!
I'm going to attempt to look at the firmware..
