This is my "Smoke" Test Machine. It sits just to the left of my Main Apple //e.
Right now it has a Mockingboard in Slot #4, I just won it in an eBay Auction ( Sorry in Advance if I bid against you ). The Mockingboard works great, but had no Speaker Cable or Speakers ( I am using the Two 8 Ohm speakers from my Two Echo ][ Boards ), and the Left Chanel Volume resister is broken, so it has to be Taped On to work..
This machine had a Damaged 64K 80 Column board, Alkaline Battery Acid dripped down on the the Board and Slot. So the Aux Slot won't work any more.. I might be able to clean it up at some point... But for now it is "stuck" at 64K. It was built Later than 1985, so it has the Darker Key Color and Black Letters, and was Factory Enhanced. So I thought I would use it for a "Smoke" Test Machine, instead of the Broken Case Apple ][e, but the Keyboard is connected to the Upper Case..
