83620的组件级别信息是否仍然可用？
我知道在某些时候它是，我正在寻找关于A20射频接口板J4上的引脚输出的信息，特别是引脚4,5,13,​​15所有其他引脚似乎是GND和电源但这些似乎是一些
一种控制线，我正在阅读旧的惠普期刊中的LB模块的描述，但它并没有表明有任何控制线来自或进入LB模块，但我的假设是那些可能是锁定检测线和

  Is component level info for the 83620 still available ? i know at some point it was , i am looking for information on the pin-out on J4 of A20 RF Interface board especially pin 4 , 5, 13, 15 all the other pins seem to be GND and power but those seem to be some kind of control lines, i was reading the description of the LB module in a old HP journal but it does not indicate that there are any control lines coming from or going to the LB module but my assumption is that those are probably lock detect lines and some other self-test lines, i would appreciate any help !
I got a old 83620B from salvage im trying to repair , it seems to work fine except of the LB module and sending it in is not a option since its too costly !
