TIMEOUT!!

Jim, you have said is true of NEWER 6300s ONLY. The older model (CPU-3) did
indeed have the STUPID soldered in chips. I know this for a fact. In fact
Many of the VERY EARLY 6300s have had soldered in chips, right down to the cpu
(8086) chip. 

Silly, I know, but true. All you current and future owners should note that
AT&T does not do this anymore, I think 512K is stock now.

Your explaination is correct otherwise, thanks for putting it out.
George
