haha this terminology is quite confusing. i see some people use peripheral and midgrade interchangeably. i see that this isnt very accurate though. generally the difference between midgrade and "peripheral" is the presence of heavy alum and transformers on midgrade. often times though, i find after removing the heavy objects there are enough IC chips to qualify it as peripheral. Am i correct in making this assumption? Is there a general consensus that midgrade is a lower grade than peripheral and they are two distinct categories? thanks to anyone who clears this up for me
