There I was installing a new motherboard, and I noticed something about the back metal plane that I hadn't seen on any other 3b1 I had taken apart. The back plane was extended across on the right hand side (underneath the floppy drive), and it contained a large cut out. Normally the back plane drops down as I show on the left side. Now, this cut out cannot be seen when the cover is on because the fan grate covers it. Has anyone else seen anything like this? The machine has a 67 meg drive and a high serial number. Under the cover there is writing dated April 1986, so that puts it towards the end of the production run of these machines. A funny coincidence is that I was planning on adding a second hard drive this summer. All that I have to do for cabling is cut away the fan grate and drop in a socket! phone parallel serial UNKNOWN screw jacks port port screw CUTOUT!! |-------------------------------------------------------- ________________| o [_][_][_] [____________] [_______] o [__________] | | | -------------------------------------------------------------------------- | Expansion #1 | Expansion #2 | Expansion #3 | | | | | -------------------------------------------------------------------------- -- Roger Florkowski {uunet!uvm-gen, attmail}!banzai!roger The People's Computer Company `Revolutionary Programming'
