It helps quite a bit. However, my question about TALK ATN Turnaround does not seem to be addressed in the document, and I have some questions about pedantic use: When I receive a 3F (and possibly 5f) as a command, should I ignore CLK until ATN goes high? I am assuming that all devices will read any any bytes sent under ATN. Is this true? Your document talks about devices 4 to 30 (04 to 1e). I thought the bus could handle device 31. No? -- Jim Brain, Brain Innovations email@example.com http://www.jbrain.com Dabbling in WWW, Embedded Systems, Old CBM computers, and Good Times! Message was sent through the cbm-hackers mailing list
