What is bit 8 of KDB CR set to the first time the monitor reaches NEXTCHAR? Is it still set to 1 from where KDB CR was set to A7 and if so what does it read from KBD? According to the Apple 1 manual bit 8 is cleared when you read from KBD, but this is the first time you are reading from KBD. The monitor also calls ECHO to output what it reads from KBD and increments the text index. I would appreciate any clarification on this.
