Just wondering if you have any thoughts,

I have loaded the ZEN image to run at 2800h on an expanded Elektor Z80 system. The first 2K is a simple home developed monitor, using RST08 for serial output and RST10 for input. I have RAM from 0800-8000h [It runs Grant S's NASCOM basic with no modifications]. However when I fire up ZEN I just get HuH error whatever I type ?
