I turned the machine off, key in SP position, pressed the three upper buttons of the first column on the left (buttonnumbers 1, 2, 3) turned it on. ==> three beeps, then "busy" as headline, after that, headline: "RAM#01 200000".
Next thing: turned it of, pressed the three buttons on the left in the third row from below buttonnumbers (4, 10, 16).
Bear in mind what your doing here is a ram test and it will have the same result everytime, you'll lose everything.
If you simply want to do an initial reset than it's a similar procedure just use the the 3 buttons running from the left to the right on the third line up from the bottom of the keyboard.
