Octal II Prototype (final? version) fabricated and under test (7/01).Octal I Prototype (full function) fabricated and tested. All okay except for some minor problems with DAQ ranges, etc.
About 4,400 ASDLite chips (17k channels) have been produced and packaged, and are being tested. See slides with status report and some photos. Matching mezzanine boards have been prototyped and will be produced in quantity shortly.See Data Page for ASDLite chip.
