I am trying to write a real-time program for a Data General
Eclipse AP/130 computer, using a 4330 Analog Data Subsystem.
At present, I can not run the digital to analog converter
faster than 4 kHz. At the suggestion of Data General, I switched
from AOS to RDOS, and then from RDOS to RTOS. Under RTOS, I can
run the D to A at 8kHz, but only if the system is not doing
anything else.

Has any Data General user out there ever dealt with the Analog Data
Subsystem? I absolutely must run the D to A at 8kHz, and need to be able
to run the rest of my program also. If you have any ideas about what I
might be doing wrong, or how I should proceed, I would greatly
appreciate any suggestions (or even pointers to someone who might know).

Also, I would be interested in sharing experiences with any RTOS users,
as RTOS is a category C unsupported product...

If you have any information that might help, please reply by mail.
