Surely not. The video data will be part of the multi pin power supply connector. Video and system timing are closely related on classic Macs. The two pin connector is probably the speaker. >Question 2 - The MB has 4 simms on it, labeled Samsung KMM591000A-8.

The 1000 in the part number seems to say 1 MB each.

More likely the size of the RAM. It was common to have selectors for supplying the correct power to RAM devices. Sometimes one had to cut resistor leads. >This SE came with an external hdd called "DirectDrive 40" by Jasmine >Technology. I lack the cable needed to connect it to the Mac, It will be 50 pin SCSI. You'll need one that fits the Mac with a 25 pin "DBM" connector which connects a batch of grounds to each other. Whatever the disk has at the other end. Probably a 50 pin "blue ribbon" which was the SCSI standard at the time. It ought to be a freebie these days. Some of the cables used with iOmega's Zip drives might be appropriate. > any ideas >where I can pick it up as well as other mac peripherals (It came with a >keyboard missing a dozen keys and no mouse - I'd need a new one of both.

You need the Apple maintenance manual. They were available as Hypercard stacks but most have been converted to PDF files. Yes. Apple still considers them secret but they can be found on the internet market. There will be no information on the proprietary Apple chips but there will be a picture of the motherboard telling you what it what. Google? Some folks have CD-ROMs for a few bucks but you'll need more than an SE to read them. I'm new to this list. It's possible that LowEndMac Inc. needs to preserve its status with Apple by suppressing comments like the one above.
