Hi, I have an MCB251 board, which I'm running in 8051, non-page mode. Is there any memory space available for mapping another device, such as an ADC or and external 8255 I/O chip? If so, how do I access it? I've got a connector going to the "8051 interface pins", and I can build circuitry to demultiplex the A/D bus, but there doesn't seem to be any address space available. Thanks, Tom
I should have mentioned that I'm using the monitor (Monitor251). Thanks, Tom
