The things I like the most about this Macbook model is as following:ġ) The battery, memory chips and hard disk are easily upgradeable, no need to be a tech savvy. Still amazing (as a kid's gift for school and media consumption) Verified purchase: Yes | Condition: Pre-owned Though the MacBook was listed in eBay r unning OS 10.11.6 (El Capitan) it was running the original OS: No problem After setting it up with my information, LAN, Airport Extreme PW and my Apple ID and PW it was a 2-2 1/2 Hr download over our internet ISP connection. The laptop was restored to factory settings. Simply put, even with the cracked hinge, the old one is perfect for sitting in my recliner and connecting to the internet. You might be wondering, if both are identical why not swap the RAM. The Original MacBook 2010 has 8 GM of RAM, but, The installed 4 GB of installed RAM in this one handles the recording with no problem. I ordered it because it has the same hardware that allows the versatility of swapping the head phone jack from output to input in System Preferences allowing me to record directly into Audacity (a recording software) from the church sound amplifier. The MacBook Mid 2010 is to replace an old one with a cracked hinge being used to record the sermons at church. The CGPCS-Lite is fully compliant to ITU G.709 Annex E and IEEE 802.3-2012 Clause 82.Excellent value for money. The CGPCS-Lite core performs the 66/64B encoding/decoding, alignment marker insertion/removal and PCS block sync function between the CGMAC and the OTN core. However, for OTN application, the CGPCS-lite converses with the CGMII signal (of CGMAC) to and from the “serialized PCS-R” signal from the OTN Core. In a typical Ethernet application, the CGPCS-Lite connects to PCS-MLG/PMA on the server side to form a complete PCS layer function for Ethernet. The CGPCS-Lite core interfaces with CGMII and Serialized PCS signal. For complete Ethernet application, the CGMAC seamlessly integrates with Alphawave PCS/PMA cores. CGMAC core can be used in switch, interface card or can function as statistic performance monitoring (as MAC/RS monitor). The CGMAC supports MAC function, MAC control function with PAUSE frame and RS function according to Clause 2-4, 31, Annex 31A/B, and Clause 80-81 of the IEEE 802.3-2012. The CGMAC is an implementation of IEEE 802.3-2012 compliant to MAC and RS layers. It is an excellent solution to the 100G Ethernet over OTN application. The Alphawave CGMAC-PCS-Lite IP core consists of the CGMAC core and the CGPCS-Lite core.
