I don't know enough about the Model T's, so I'm wondering if it would be possible to use two serial devices at once: The modem port and the standard serial port. If the modem hardware, which I'm not using for anything, was replaced with normal RS232 signals (at a reasonable speed), it could theoretically be used for a dedicated MVT100 type interface, right? Then one could use the serial port for NADS or other disk storage without disconnecting the 80 column screen. Or is that just crazy?
