At the risk of turning you into more of an appreciator, here is how to run Trek80 on your SOL: 1. Assuming that you have your cassette player properly attached to the SOL, press the "play" button - the tape won't start until the SOL tells it to. 2. Make sure your CAPS LOCK in on. Then at the '>' prompt enter XEQ <return>. 3. Alternatively, enter GET. After a few moments the SOL will respond with something like 'TREK80 0000 23AB' (the beginning and end addresses). Then enter EX 0 and you are aboard the Enterprise. BTW, I would make a copy of the tape rather than using the original. Old tape literally get flakey, and I've had to replace the pressure pad on several of my original PT tapes. And if you like Trek80 as an arcade game, you must try TARGET by Steve Dompier. It was almost always used as an attention getter in its demo mode by PT dealers. You fire missles at 'airplanes' and if you play an AM radio nearby, you can hear the sound effects of missle launches, explosions, and falling debris. email me with your address if you would like xerox copies of Trek80, Target, or most SOL documentation (though I don't have FOCAL docs or a copy of that tape - are you listening, Frank?)
