3/303/8

pulse = 100 - |number mod 2| × 50
Use dst instruction can force set acc to negative, without any test instruction.

3/303/8 O_O

I abused the behavior of dst when the 2nd operand isnt a simple single digit number
and I also didn't use braching

Best Attempt: 5/452/14

Worst Attempt: 17/776K/50 (I actually tried to be inefficient.)

3/341/9
7/189/5

Yeah, I know I didn't need dgt though it was something I missed in my fast and initial attempt. Like I said, it was a mindless approach where I wasn't analyzing as closely as I should.

price: 3 / 303 / 9
power and lines: 7 / 189 / 5

@ lisamariefan
When you are using the ROM you don't need dgt and dst

And...7/189/6 as I could cut out a move to the accumulator...
lisamariefan 2018 年 7 月 24 日 下午 12:57 
I was really unthinking in my first approach and had an unnecessary dgt 0 in my code. New approach is 7/227/6.
lisamariefan 2018 年 7 月 17 日 下午 8:12 
I'm sure there's more efficient ways to do this, but my first rather unthinking approach was 7/265/7

2nd hint:
The 'dst' instruction :)

Is 3 / 303 / 9 the best cheapest solution?

For such a trivially simple problem, the complexity created by the I/O & operator constraints creates a surprisingly large number of approaches to solving it.

It seems somebody got it with less than 5 production cost (i.e. without an MC6000). Any hint how that works? The shortest I got the code (without using a ROM) is 11 lines.
