Willard GooseyAtariSoft Battlezone booter on Tandy1000
I don't think it's tandy /pcjr compatible, it seems to corrupt itself...
Or it's a copy protection thing...
(also it expects a 4MHz machine and my 1000sx is running at 7.xx and the games a booter so there's no way to run a program to slow the clock down first... Games don't last long.😒)
