Great link, thanks! HDD goes chomp, chomp, chomp...

I have an NTE one and I used to have an ECG. Not sure what happened to 
that. I think the ECG one is better. NTE seemed to have a limited 
repertoire compared to ECG (like 20 0r 30 years ago, ... whenever I 
bought them). I remember ECG also came on a searchable CD or set of 
floppies at one point. I might have that in a box somewhere. I think NTE 
bought out ECG some time ago.

Another decent one is Towers International Transistor Elector. Easily 
found on eBay.
