Talking of the 380Z...

Since the 380Z seems to be popular at the moment, does anyone have info on 2 bits that are not properly described in the Information File? The first is the dual cassette controller. The pinout of the 7 pin cassette socket is given, as of course is the schematic of the VDU board that contains the cassette circuitry. The controller seems to contain a couple of relays to control the recorders (were these powered from the system 5V line or a separate power supply?) and switching to allow either one recorder to be used, or two with one used for recording the other for playback. It's possible to make some guesses as to how it was wired, but some real details would be nice The second is the SIO-2 board. This was a bit-banged serial port using, IIRC, 3 lines of the user port. 2 ouput lines for TxD and thr reader control relay, one input for RxD. At least knowing what port bits were used would be a help... -tony
