IM0 - and now another test!

Hello, boo_boo It’s my turn to pester the real people with requests. This time only owners Pentagons, please help and drive away this simple TRD (other files I I have attached pictures for completeness). Excerpt from the description: Run the test only on the Pentagon - Scorpios are not suitable. (If ATM has Full compatibility with the Pentagon, drive in this mode). For branded models The test is not calculated at all. The test prompts you to enter a correction number from 0 to 30 before each pair of checks. In EmuZWin it works = 18, in UnReal/Spectaculator/RS = 14. In a real machine it is the number may be different (hopefully the range 0..30 is enough to satisfy the test). If the correction is entered correctly, then the green curb should stand and not move at all! And then it’s interesting how the curb will behave after pressing the next button. If it will remain in place, then IM0=13 clock cycles, like IM1. And if it goes (up), then = 12 bars. Also of interest is the magnitude of the correction at which a stop is achieved curb. And a note: in Spectaculator, judging by the test, IM0 is already equal to 12 clock cycles. And in RS and US - 13. We are waiting for the benefactor to bring the light of truth to the column of mystery... File: IM0test.rar http://zx.pk.ru/attachment.php?attachmentid=3019
