Wiring diagram for a homemade RS232 cable connecting the Cambridge Z88 (DB9 male) to an IBM PC (DB25 female), tested with PROCOMM software on the IBM. The cable also works for connecting the Z88 to the TS2068 via a Z-S10 interface (attached to the modem cable end), and for linking the QL SER2 port to the TS2068 Z-S10 interface for file transfer with XMODEM using Specterm 64 on the TS2068 and Q_Link on the QL.
