I just double checked and on the other unit it is a
74S299N, identical to the one that gets hot in the VT100. I suspect it is OK for it to get
hot and maybe I should just stop worrying about it. But it is puzzling as to why this one
gets hotter. I will get my VT101 back soon and I can see how that compares.
Should you be worried about why the other one is running "too cool" :-?
