Analogue systems

Regarding the anomalies with the RS290:

The 290 is somewhat groundbreaking in that it's the first time (to my 
knowledge) a DSP-based device has made it to the analog domain, complete 
with analog VC.  Undoubtedly, something like this may have some bugs at the 
onset. Afterall, it's a huge undertaking.  While it's fairly simple to write code so 
that certain input conditions will cause certain things will happen, it's really 
hard to find all of the instances where random input combinations you weren't 
intentionally considering when programming take place which may cause the 
code to step on itself and crash the device.

While IBM may have buildings full of programmers doing nothing but code 
QA,  I'm sure A Sys isn't quite as e


There are two reassuring thoughts:

1) If you have the optional expander (RS295), new operating systems will be 
uploadable into your RS290 at a later date - so these bugs are repairable for 
units already out in the field.

2) Knowing Bob Williams' attention to details, all of these problems will be 
taken to heart, addressed and corrected.  It may take a little bit to get a fix, but 
in the meanwhile, we have a great instrument to enjoy - the 290 is a lot of fun.

Fortunatel, none of these bugs make this module unusable in the meantime, 
so I am not too worried.  Knowing about them, we can easily avoid the 
situations which cause these problems. The best advise I could give is that we 
continue to post future amonalies here in this  forum so that A Sys can get the 
411 as needed to replair them.
