I thought I was subscribed to the ML, but come to think, it's been a long time since I received anything from them.
Actually, the M100 is just acting as a terminal, with the real telnet session running on a nearby PC (Mac?), the same way that I used to use mine to access my unix shell account(s), only I was hardwired to the PC thru the serial port. It's the wireless thing that's kewl (and new to me).
I get the impression that the BlueSMiRF hardware can be used with other vintage computers as well. Seems simple enough, only four wires are necessary, +5, TX, RX & GND, coming right off the you-rat. I'd kinda like to try using my PX-8 on the I-net.
