The BUS connector, what use is it? For connecting things. Presumably people built boxes that could be connected to the machine at this point. How does the disk drive connect? Probably here; but I don't know. > 4. What are the pin configurations for the phone plug and Cassete plug > (and has anyone used them successfully outside the us) I'm about to find out about the phone socket; call me back in a few months and I'll let you know what I've found. The cassette socket is useful for controlling small DC loads such as a remote alarm system... otherwise use it for cassette storage; like it was originally designed for. There is a cable that connects from the socket to the cassette recorder. Pin connections are in the manual... which I haven't got with me right now. > 5. TELCOM > (a).

Can anyone list all that you can change with the STAT > command, and the options for each, i.e. which letter > changes baud rate, parity, etc etc Yes; but I'd have to bring in my manuals... let me know if you want me to do that. From memory, the first digit is baud rate or M for the built in modem. 9 means 19200; that's all I know off by heart. The second digit is bits per byte. The third is parity; None, Even, Odd; at least. The fourth digit is stop bit count; 1 or 2. The fifth digit is E or D meaning Enable or Disable the XON/XOFF protocol. On US machines, you can specify the dialing pulse rate after this digit. > 6. BASIC > What other M100 specific commands (like DATE$,Day,time,IPL) > are there. Heaps. At least this is so on my Model 102. It occurs to me that you haven't got a manual for the thing. If this is so, maybe you should approach Tandy/Radio Shack for a copy? I've got two for the Model 102, but I want to keep it that way for a while. >This is a pretty tall order, but any help anyone can give me will be really >gratefully accepted.
