Where can I find the memory map for an Ibm Pc Jr running DOS without memory expansion. How about the I/O map? Is anyone familiar with the wireless keyboard interface for the Pc Jr? Does the microprocessor handle the infrared decoding or is it handled by separate hardware? I am particularly interested in decoding the signals myself so that I can send commands other than those sent by the standard keyboard. Does anyone know the address and/or phone number for the Pc Jr user's group in the St. Paul area? Rereading this I see that there is significantly more than one question but counting has never really been my strong point. (Isn't that what computers are for?) Any and all hints/suggestions/comments will be greatly appreciated. INTERNET phinker@aring.eta.com
