I can tell you what the components are (I used to build electronic
circuits for a living);

MAX232 converts TTL voltage levels (5V & 0V nominal) to RS232 levels
(+/-12V nominal).
The 74HC04 is an inverting buffer.
The three pin black device by the red LED is probably a voltage
regulator, since there appears to be a power cable. 
The silver item labelled 6.000 is a crystal.
Assorted resistors and capacitors, and two diodes.  Plus the LED of
course.

Is the big black block a PCMCIA connector, perhaps?
