A couple of the dev boards I've been experimenting with have a fused quartz window leaving the chip visible, offering the perfect opportunity to take a few close up photos.
The 87C752-5F28 is a Harvard architecture microcontroller based on Intel's 80C51 with 2K EPROM and 64 bytes of RAM.
The M27C4001-15F6 EPROM is a non-volatile 512K memory chip. The memory is normally written with an EPROM programmer and erased using ultraviolet light.
