Hello to the members of the bitchin100 mailing list. I am a newcomer to the list and am posting here - at the suggestion of MikeS - because I am the new owner of a Model 100. It is my first TRS and I have a lot to learn, although the VCFED members have helped where they can.
I have some documentation: the Radio Shack Model 100 manual and a book The TRS-80 Model 100 Computer, by David Lein. But I have a question about the expansion ROM port and am hoping someone can help me to understand better: In the expansion bay are two sockets; a 28-pin and a 40-pin. The 40-pin is referenced on page 208 of the RS manual as "40-pin extended bus" and a chart of the signals is given along with a pinout diagram. What is the purpose of this bus? Was / is there any device that used it? Am I correct in assuming the 28-pin socket is used for the ROM Module Cartridge referenced on page 8 of the RS manual? Thanks for your replies. -CH- picture attached. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
