IIx Front panel circuit board connections please and some help!
2006-01-04 by twharleyman
Hi All, I am trying to revive a Series IIx that had previously been missing the front panel and has sat idle for many years. I managed to get a new panel made several years ago and had the circuit board but I dont have details of how this board connects to the other cards in the mainframe. I can see that it should possibly connect via a 20 pin connector, the one on the side of the board, to the CPU control card but I'm at a loss where the bottom connector goes too. Is it there for test purposes only or does it link to another card. I've had a look at the IIx Service Manual but this doesn't realy help. Ideally a picture of the front panel opened up would be a great help. Apart from this I also have a problem with the CMI-02 card which prevents the system from running and causes a series of vertical lines on the monitor. It was working before but I think I made a bad connection while trying to sort out the front panel! If the card is removed the system will start to boot a system disk (stops because the CMI-02 card isn't there so there is no music system!) or fully boot an OS disk. Anybody got any tips what to look for on the board? Thanks in advance. Tony P.S. if you have a photo please send it to my main email address twharleyman@tiscali.co.uk
