Sorry, minor goof on the drawing. I got the game port and the 1st serial
port backwards. Corrected drawing follows:
10-pin plug (optional COM2?)--+ +--16 pin plug
+------------------------------------------------|----------|-----+ (game
| +------------------------+ +-------+ # ======= ========== | port)
| | empty spot for 2nd | | empty | # ||||| <--5 jumpers |
| | serial port UART | +-------+ \ |
| +------------------------+ +-+ +-------+ 4-pin plug +-+ +---+9 pin
| +------------------------+ | | | empty | (pin 2 gone) | | | |serial

Again, does anyone recognize this card? Can you tell me which dipswitches
do what? Thank so so SO SO MUCH!
