Regarding the S-100 Serial I/O board
(http://s100computers.com/My%20System%20Pages/Serial%20IO%20Board/Serial%20IO%20Board.htm),
why is the oscillator (P56) specified as 4.91*6*2 MHz Oscillator, full
can, rather than 4.91*5*2 MHz?
This drives the 85C30, and 4.9152 % 16 = 307.2 kHz ==> 19.2 kBaud.
I presume that this is an overlooked typo in the schematic and parts
list ... right?
