Guys, I'm typing this on my phone, so bear with me till wednesday when I have a real keyboard.
IOU... Definition of jargon, rationale of why an engineer does a ROM calculation when he lacks necessary data, and a narrative explaining, simply, what that calc. post was about.
Thanks 44man for the pictures... Have a couple of thoughts about your picture that I will save till wednesday, but there isn't enough resolution to see much about the base edge of these. A profile picture might also add something...
Bret, anything simple can be made impossible to understand with an incomplete or poor explanation by the author. I'll try to improve the explanation and then we can go from there.
Best regards, DrB
/EDIT: Alright, so I added a lead-in to the calc post on the prior page that should be a good start to satisfying the above. Bret, let me know if it helps/if you have any questions? /EDIT
