Hi-I am a struggling EE student who is fairly new at programming the HC11. I ordered the NMIN-0021A board for a project I am attempting to build for school.I am a little bit frustrated by the lack of documentation for this board. I have scoured the docs that came with the board to no avail. What I am looking for is some pinout diagrams for the 42-pin male connector on the side of the board opposite the 25-pin serial connector. The connector is labeled "J9" on the NMIN-0021A board.We are attempting to use this connector to connect our chip to some other circuitry but thus far have been forced to reverse-engineer every pin that we've wanted to use. This is a slow and frustrating experience.Is there a better way? Even if it was just in list form like:pin 1 = Ground pin 2 = Vcc pin 27= 6811portA bit 1 ... (etc)(Those are bogus values, but you get my point)Is there anything out there like this? Has someone already charted out these waters? Any and all help would be immensely appreciated.Thanks much.-Peter (starving EE student at University of Utah)

The pinouts from the silkscreen or schematic of the NMIN-0021A should look like this, Pin# Name Pin# Name ~~~~ ~~~~ ~~~~ ~~~~ 1 GND 2 RST' 3 PE0 4 PE1 5 PE2 6 PE3 7 PE4 8 PE5 9 PE6 10 PE7 11 PA0 12 PA1 13 PA2 14 PA3 15 PA4 16 PA5 17 PA6 18 PA7 19 PB0 20 PB1 21 PB2 22 PB3 23 PB4 24 PB5 25 PB6 26 PB7 27 PC0 28 PC1 29 PC2 30 PC3 31 PC4 32 PC5 33 PC6 34 PC7 35 PD0 36 PD1 37 PD2 38 PD3 39 PD4 40 PD5 41 PD6 42 PD7 43 E 44 +5VRTS': reset low signal E: system E clock PD6: same as STRA PD7: same as STRB GND: Ground All other signals are HC11 I/O Ports: A,B,C,D,E If you did not receive the schematic and the silkscreen with the NMIN-0021A.
