    The only expansion ever made available for the 1400 series, as far as I know, is the CompactFlash Adapter for the Tandy 1400 Laptops. The 1400 series has 768KB of RAM, which is more than the typical...

    What would you use a second serial port for in a Tandy 1000 EX/HX? One for a mouse is a must, no argument there. What about the second port? XYZMODEM-Null Modem transfer? Slow and less than 100%...
