Tom:

First thing you should do is test the two ports, the PC side and the

Apple II side. Put both computers into terminal mode. Use a paperclip

and short holes 2 and 3 together and type. If you get the characters on

the screen, the send and receive work on that computer. If both

computers show good transmit and recieve, then it is your cable that is

not quite right. Of course I'd immediately suspect one of the

handshaking lines didn't get crossed.

If the IIe is actually not sending out, replace the 1488 chip at A6.

Assuming you look at the end of the SS card where the cable plugs in,

right side up, there is a black plug, rectangle 10 pins which I will

number as follows.

1 2

3 4

5 6

7 8

9 0

DB25s are normally numbered front and back, gender is irrelevant. The

Signal labels assume the SSC is in the MODEM mode.
