I finally got my hands on a working 400K drive. I was able to pop it in the 128K and boot it up. Turns out, it is still a 128K. The little switch that was modded to the main board bumps the RAM up to 512K. Kinda neat. Eventually I'll get a non hacked board for it. But it is nice to see that it is indeed still a 128K. I was really looking forward to using the machine and getting a feel for how much you can do with 128K. Plus, like said before, it's all abut getting an authentic machine.

Booted up in 128K mode:



Flicking the switch on the back and booting it up bumps the RAM up to 512K:
