Since someone mentioned that the interrupt board only makes a few connections to the bus, it should be very easy for someone who has one to provide which pins. One will be ground, one will be +5V, one will be the interrupt pin, and then the last one has to be clocking. It should be really easy from there to figure it out, without actually having to trace the rest of the circuitry on the interrupt board.According to a IIgs motherboard, the pins of the slot are numbered 1-25 front to back on the right side, and 26 to 50 on the left, back to front.The card's fingers touch pins #19, 25 on the right, and pins #26, 30, 40, and 41 on the left side.
according to the apple II reference manual, pg 106 those are: 19 = n.c. (no connection except for slot 7 where it is the SYNC from video) 25 = +5 26 = GND 30 = IRQ 40 = (phase 0 clock) 41 = device select I would like to see a clock/calendar option to the ethernet card. A quick check and Dallas semiconductors has a chip DS1284 that would work with a little glue logic. Jim
