Does anyone recognize what IRQ Address these dipswitches are set to? Thank you in advance for any help. I don't have the technical documentation for these boards and I'm a newb. http://img197.echo.cx/my.php?image=dcp18896ej.jpg&tc=img197/5261/psxcollection8il.jpg
From the insatallation instructions - Step 1: Determine a free memory address and a free IRQ for your boards. By default, the dip-switch/jumper settings of the board are set to [font="] IRQ: OFF[/font] [font="] Base Port Address: 1340[/font] You will have to set the jumpers of the board to an available interrupt and address. Follow the installation instructions entitled "PlayStation Board" (for PC/AT) that is packaged with the boards. Note: You may have to refer to the Japanese version of these instructions to see the value each jumper setting corresponds. This is because the English version may be illegible. The interrupt and address you choose should not be in conflict with other boards on the system. The jumper (or dipswitch) settings game on a separate (photocopied) sheet of paper which unfortunately I don't have. You could start by assuming the default, other than that, you have a 1 in 2^12 = 4096 chance of guessing the right settings
well, you don't NEED the IRQ - so you could get away by turning it off by setting all switches pertaining to the IRQ to off. The question is, which switches :-( The system might be similar to the Psy-Q SCSI board, where the IRQ and I/O are encoded simply in binary - with ON meaning 1 and OFF 0, and the sequence of bits making up the IRQ. That would make the bank of 4 switches on the left the logical choice for IRQ (0 to 15, which is exactly the normal IRQ range).
