Here was this inexpensive computer from Radio Shack, already on the market, that would if you used OS9, also available from Radio Shack. About that time, I decided that Bill Gates aught to pay more attention to what was going on. At that time, my concern with, and about, power backup units was somewhere between none and none. I did know what one was, what it did, and why it was desirable to have one. I just didn't really have a need for one for a long time. After all, if you shutoff the PC, who cared if the power went down - as long as you shut down before that happened. As to your last statement, I'm wondering if you were saying, in a different way: they took a nice, simple piece of equipment, that did its job well, and added capabilities to it, that in order to utilize them, required more capabilities added to the units they were supplying power backup to. Ah, I see by your later post to the list & OP, given more in depth and with good advice, that's what you meant. Don
