If you have some free time, please take a look at it and tell me what you think. I believe it's better than the previous ones - I haven't added any functionality - I'm just trying to fix the current flaws, which are not few. I ran the official test programs for the 1132 and 1442, but it seems to me that these programs are very demanding regarding the machine's behavior - it is difficult to satisfy them. In any case, if DM2's I/O subroutines can handle the emulated hardware as it is, I'm happy!
