Arrived and running

My Gigatron kit finally arrived yesterday and today I finished the build. It's an amazing design!
Just with my PS/2-keyboard (Cherry RS 6000 M) or the Pluggy I didn't have luck yet. I measured the voltage at the D-SUB connector and it's a stable 5V. The dot on the micro lines up with the dot on the PCB.
The game controller works. I suspect it is one of those that are called "Type C" in the ROM as it seems to only register one key at a time. Which is fine for most things, but the Racer app is...quite some challenge this way.
So I guess next on my list is getting an Arduino so I can use that as a terminal and also for getting my own programs on to it.
Further experiments I have planned so far are software modifications to the sound system. But that is probably a topic for its own thread.
On the hardware side I would like to try to move both the ROM and the RAM to a cartridge, where the RAM could also be battery backed. The cartridge could then be connected to something else and the RAM could be saved to disk. But that is currently just a wild idea, I don't know when or even if I will start with that.
Again, I am really impressed by this amazing design!
