Re: Recommendations for EPICS Based Data Acquisition System

[Heinz Junkes <junkes@fhi-berlin.mpg.de>]

Aloha Matt,

I am still using (buying) VMEbus stuff.

I am happy with

MVME6100 (alternative MVME2500)
Digitizer Struck SIS16
MAXv motor controller
Highland waveform generator

Running RTEMS 5 with EPICS 7 on them.

Heinz
