GitHub – dschmenk/apple2pi: Apple II client/server for Raspberry Pi

Posted by jpluimers on 2020/05/28

[WayBack] GitHub – dschmenk/apple2pi: Apple II client/server for Raspberry Pi: hybrid computer of a Raspberry Pi inside an Apple II (either ][, or ][+, or //e) so the Apple II can be a front-end to the Raspberry Pi which then can run an Apple IIGS emulator, talk to the Apple II storage hardware and much more.

It can run [WayBack] RASPPLE II: A2CLOUD, A2SERVER, Apple II Pi for Raspberry Pi

Going to test some USB 3 gigabit ethernet adapters based on Realtek RTL8153 and Asix AX88179 chips

Posted by jpluimers on 2018/07/27

Later on, I might add a USB31000S in the mix, but I will do some initial testing with USB 3 gigabit ethernet adapters based on Realtek RTL8153 and Asix AX88179 chips.

Things I will focus on with my Retina MacBook Pro 2015 model are:

  • CPU usage
  • Throughput
  • Duration between reconnect on USB after suspend, and renewing the DHCP lease
  • Promiscuous mode capabilities

Some links for my references:

A first impression from the above links is that for Realtek chipset based devices, drivers are more readily included in operating systems, and these chipsets are better at VLAN handling.
