Robotron 2084 was downloaded from MacGui as well. I tested it in AppleWin and one of the early screens shows the keyboard commands.
I downloaded it to my Apple //c using ADTPro 1.2.8 onto a disk I have used before. When I booted it on my Apple //c it jumped into the monitor at 9D86.
I tried it again and noticed I had 1.2.8 on my PC and 1.2.7 on my Apple //c. The same thing happened jumping into the monitor at the same address.
I didn’t think the slight difference in versions would make a difference but, there is a new version of ADTPro, 2.0.0. I downloaded it to both my PC and Apple //c. One really nice change from 1.2.7 to 2.0.0 is you can press enter when asked for a file to receive and get a list of available files to choose from.
I downloaded Robotron again and the same thing happened. I tried the other side of the disk, same results.
I tried another disk on the internal diskette drive, this one comes up with the right square bracket (]) for a prompt. CATALOG got me another prompt. I moved the diskette to the external drive and downloaded it again. I got the square bracket again, but when I did a CATALOG I got the ERROR #8 message.
This brings me to the same point as Xybots who posted the original question. Reproduced, but not solved.
I have never gotten that image to run, but there is “robot wars” on the choplifter disk that works
its almost the same but you only fire in the direction that you are walking
