160 baud ALDL data stream format - reference URL?

[Peter Gargano]

I just measured the 160 baud data stream from an VN Commodore 
with '808 and found that (within 50 uSec.):

       T0 to T1 was 0.5 mSec., 
   and T3 to T4 was 1.0 mSec.

       160 baud data format - 1 bit time

             S   0        1    S
         ..__     ........_____    ...   12 Volts
             |   ^        ^    |   ^
             V___|........|    V___|..    0 Volts
            T0   T1  T2   T3   T4

This is consistant with the information from Steve ...

> Time T0 to T4 is 6.25 mSec (ie 6.25 mSec = 1/160 Sec ==> 160 baud)
>      T3 to T4 is minimum of 0.5 mSec
>      T0 to T2 is between 1.5 and 2.3 mSec

but does not quite match the picture and info from ...

Anyone recently measured a 160 baud ALDL signal?
