VTech Video Painter Circuit Board

Well I just got my painter in the mail and quickly proceeded to take it apart. The images can be found in the VTech Video Painter Gallery of what the insides look like. From using this device normally I was very impressed by its capabilities. Its an 8-bit artist Mecca sort of speak, especially when using the zoom function to magnify those lines. On the inside I found a Z80 processor same as the TRS-80. There also appears to be a ROM IC which I imagine can be messed with. However my concern is that because its a fairly complicated device it may crash a lot with any attempts of bending or short circuiting. I guess we just have to wait and see.
