  Well, we have problems with three things. The worst is by far the keyboard. I am aware that AT&T has redone the keyboard to compensate for the multiple
failures of the old model, though. The other two problems are the disk drives 
(I think the main problems are with the mountings- thry tend to interfere with the internals of some drives) and the monitor. We have many a dead AT+T monitor.
They go out with alarming regularity, although with varying symtoms.

  Not necessarily true- the expansion board has very little in the way of its
own electronics. Any bad boards would still fry the mail logic board.

  RF is often a symtom of a bad design- that was why I mentioed it. A good 
example of a similar configuration (and problem) would be the TRS-80 model I,
which was removed from the market because of extreme RF problems (Plastic case).

Aggreed. It won't run any machine-specific code (Some excelent machines will)
but other than that it is pretty good. (So says owner of PC-AT)

True- but It won't work with the majojority of the 16 bit cards. 8 bit workd just fine, though. I was complaining about the lack of 16 bit compatability
becasue one can get very inexpensive 16 bit cards for the AT from alternate 
sources. However, I found out after my post that the AT&T was released BEFORE
the AT, so this is no fault of AT&T engineers. Although an update might be in order.
