One of today's acquisitions is a small card for an Apple ][ (or Apple ///), labelled "APPLE 2/3 XEBEC INTERFACE REV 1". I happen to have a couple of old Xebec ST412 winchester controllers, so I'd like to try this out. Can anyone tell me the pinout of the 26-pin header at the end of the card? Pins 3,7,11,15,17,19,21,23,25 are grounded, the other seventeen seem to be signal lines. Pins 1,5,9,13,20 are high impedance; the other even-numbered pins are terminated by a 220/330R resistor pack. Does it need any other software (like a formatting disk)? The on-board 4K EPROM contains only the strings "(C) HAL COMPUTERS LTD 1983", "A/XHAL SHARED RESOURCE WINCHESTER SYSTEM", "NOT CONNECTED", and "SRS ERROR", so I guess there would have been a floppy with it, originally. -- Pete Peter Turnbull Dept. of Computer Science University of York
