Subject: VT100 for the Osborne 1

As configured from the factory, the Osborne 1 would properly handle
300 and 1200 baud.  Given the (stupid) architecture of the machine, even
1200 baud was pushing it if you were typing at any rate of speed.  19200
baud is theoretically possible but as that's the divide by one rate in the
6850 (sio chip), the characters that you get back are about half garbage.
If you doubled the rate of the clock into the 6850, you could then get
600, 2400 and 38.5k baud, with the latter once again unreliable.  There 
simply wasn't any excuse on Lee Felsenstein's part to design the machine
the way he did.
