My RAMs arrived today, and my PICL is fully-functional. I still need to get the settings right for 'minicom' for uploading programs, it seems a bit sensitive, sometimes I get load errors and other times I don't. I also find if I edit captured files to re-upload they don't always load, so their might be spurious characters getting inserted by vi. Maybe I need to tinker with the settings more! I did also think if there is space on the microcontroller then some kind of buffer could be implemented to ease the flow control problems, but that would be an experiment for another day.

I also am finding the LEDs a bit bright, so I could have used the 470 ohm resistors I had rather than the 330 ohm resistors I bought, so if others are building one then I'd suggest experimenting with the value before soldering everything in.

Now I'm just thinking of ideas of what to do with it!
