LISA: Ah nuts...

All right, darnit I'm back. I moved jobs, started my new business and found out the new business only requires about 20 hours of my time every month and a half. :-/ And I've still got a garage and basement full of iron beasties waiting for resurrection. So... (BTW, Allison and Don Maslin, I think I owe each of you $5 for some docs and disks you sent me.) I opened up my Lisa with the bad video (weird horizontal sync problem) and discovered that the batteries in the back have corroded and dripped down the I/O board. Some of the contacts that go into the motherboard have corroded and, without seeing a schematic, I'm wondering if this is causing the sync problem. I verified that it's the video driver circuitry and not some malfunction of the monitor by connected a monochrome monitor to the Video Out jack on the back and seeing the exact same behavior. At any rate, I removed the offending batteries and will clean up the board. Are the batteries necessary? If so, what for? If so, what is a viable replacement for them? Is my theory about the video plausible? I've got images of bootdisks etc floating around in an email box somewhere on the backup tape from which I had to resurrect other email messages so once I get the video cleaned up I'm ready to rock and roll I think. Also, I have a Profile harddisk that alledgedly goes with the unit. Without documentation, I see no place that indicates a hard disk should be connected there on the Lisa. But the Lisa has one parallel port and an expansion board with two more parallel ports. Does it connect to one of these? If so, what cable is appropriate? (No cable) And to what should it be connected? Thanks in advance for advice and assistance... Anthony Clifton - Wirehead
