See photos.  Comes from an immaculately clean nonsmoking home.   We have no way of testing this.  Likely from the mid to late 1970s.  During research, we could not find it, but found higher model numbers attributed to 1980.  All keys push and pop without issue.  Mechanical clicky sounds.   QWERTY layout with numeric keypad.  Looks to us like an RS-232 interface.  Weighs just under five pounds.  Approx 18.75" x 8.125" x 2" tall.  Owned by a very early DIY homebrew computer enthusiast here in Raleigh, NC.  We have a number of 8" floppy drives and another keyboard available at the time this listing was created.  Seller Lot #24092.
