BAUD RATE JUMPERS
ADVANCED DIGITAL CORPORATION SUPER SIX SUPPLEMENT
Update for Page 7
With the Super Six component side facing you and the S-100 connector down there
are
7
jumpters between U68 and U70 aligned vertically. There are assigned as
follows:

Bit D for SIO CH. B is not available as a jumper and must be set in software.
Bit 7 of this input, port (port 15) is instead used to sense double sided drives.
Some software reads this bit and sends it to the SIO CH. B baud rate anyway. If
you have double sided drives, this will make the bit a 0 thru creating baud rates
from 50 to 1200. If you have single sided drives, this will make the bit a 1
and create baud rates from 1800 to 19.2K. If you experience a problem with this
you can make a file under cpm to correctly assign the baud rate to SIO CH. B
(used for serial printer and/or modem) as follows:
