IBM Advanced Interactive eXecutor machine that fits in your pocket <3
Took some tweaking, but finally its here - AIX 4.3/5.1 ppc running on the PinePhone + PineKeyboard and with full X11 CDE over Xephyr (had to use older Xephyr build since new one does not support /dev/input) - AIX is running in qemu-system-ppc on the PinePhone and is networked :)
What? A Rabbit 2000? I've never seen this before! It turned out to be a processor that's based on a Z80 instruction set. Nice, something new! It's paired with RTL8019 ethernet controller.
I've just uploaded the #Datatrak Locator Mk2 reverse-engineered schematic to Github - https://github.com/philpem/datatrak-locator-mk2
This is a long-running project (started in around 2019) and I'm glad to finally have this part finished!
Hm neither of them show up, the lenovo one only shows up wwan interface... i wonder if this mPCIe slot is just USB or something
Nice, the lenovo one works, I dont think there is a hardware whitelist

#Starlink user terminal transmission, single frame.
A clearly visible pilot tone that uses for doppler-shift correction, I guess.
Preamble duration is ~43 us.
Look at him goooooo

I can't sleep so will try to do something about this - the previous owner had a big heatsink + a PC fan here, but it's too big for my classic A1200 case, so need to replace it with something smaller
The #Datatrak Locator Mk2 schematic is coming along nicely. Finished the 68K and 8031 CPU schematics and I/O, which just leaves the LF radio input to enter into KiCad.
While playing with modems, I realised that I have to build a more professional setup for my dial-in concentrator. I got annoyed about several modems tipping over when I'm connecting cables so I built this from various parts I had gathered over the time.
