This is interesting ... I assume that you made some
changes to both the hardware and software? The specs
say it has band width of 4-20 Hz and 64 Hz sampling.
It sounds like Jim also based his design on the HAL
as a starting point and made some changes in the
input section, then changed from 8031 to 68HC11 uC.
Are you saying that Roshi is based on a modified
HAL? Where can I find info on Roshi, is there a web
page now? How much $ for the infamous Roshi?
