She's a beaut! I had snagged it off of CL sight unseen with not a whole lot of description, but I was pleasantly surprised today when it arrived.
It ended up being a Rev 4.X board inside (a sticker on the board says 4.3, the graphics on the board say 4.1), the battery had been removed long ago with no signs of leakage. It came with a 2091 SCSI pre installed with a Hard drive already loaded with programs. Also a SCSI Cdrom loaded with stuff I can't even read due to the fact I have it plugged into a TV and the output is black and white

The floppy drive is a bit borked, but works. Now begins the exploratory fun, right after I snag up a monitor to run with it.
sysinfo says its ECS Agnus, 1M chip ram, 2M fast on the SCSI card, workbench 40.5 and Kickstart 40.63.
