Sounds weird. I checked it out, it IS weird. I assume you are 100% sure that the program on the real Plus/4 is byte-to-byte identical to the downloadable prg file, but I still have to ask... Are you 100% sure? 
Let's start with the real machine. Line 13 is perfectly innocent, as long as we're in multicolor graphics mode. I'd guess there was a typo (or some kind of transfer error), so instead of grA3,1 is says grA1,1, so the DRAW 2, whatever throws an ILLEGAL QUANTITY. Or could there be something up with the loop counter?
About the emulation part: no idea. I'm being soo helpful, aren't I?
