| Bugs | |
| 1. IO: Channel WAR not cleared after memory store | |
| 2. IO: dev_map should contain _flags, not _v_flags | |
| 3. SYS: Errors in system tables | |
| 4. SYS: Character conversion table had 0 (space) as illegal, should be -1 | |
| 5. IO: Channel CPW calculation wrong for 12b mode | |
| 6. RAD, DSK, MT: Instruction masks wrong for RAD, DSK, MT | |
| 7. IO: Missing subscripts in dev_disp references | |
| 8. RAD: typos referencing DSK | |
| 9. IO: SKS 3 call incorrect | |
| 10. DRM: Drum track mask width incorrect | |
| 11. CPU: Memory management trap left reason in bogus state, stopped simulator | |
| 12. CPU: Interrupts require api_lvl as well as api_lvlhi, like PDP-10, PDP-15 | |
| 13. CPU: Bug in find interrupt request | |
| 14. CPU: Interrupt priority scheme recoded for left to right priority | |
| 15. CPU: overflow test coded backwards | |
| 16. CPU: Rotates operate mod 48, not with upper limit of 48 (manual incorrect) | |
| 17. CPU: RSH not handling >= 48 correctly | |
| 18. CPU: CNA is 2's complement not 1's complement | |
| 19. CPU: MUL failed to mask cross product correctly | |
| 20. CPU: EM2, EM3 test using wrong 'channel' | |
| 21. CPU: EM3 test tested EM2 instead | |
| 22. CPU: POP must save EM2, EM3 like BRM (manual incorrect) | |
| 23. CPU: Shifts need special EA calculation, direct cycles using 9b indexing | |
| 24. CPU: Shifts ignore addr<13:14> | |
| 25. CPU: Diagnostic uses undefined shift 'normalize cyclic' | |
| 26. CPU: Divide 2'c complement of AB leaves B<23> unchanged | |
| 27. CPU: Divide overflow test requires special cases for divd.h == divr | |
| 28. CPU: Divide uses non-restoring algorithm | |
| 29. CPU: Channel terminate output must be deferred until channel buffer clears | |
| 30. CPU: Channel terminate output to magtape is convert to scan, must be | |
| handled in channel logic | |
| 31. SYS: duplicate entries for shifts | |
| 32. SYS: mask for shifts did not include indirect flag | |
| 33. MUX: Genie/SDS use inverted meanings for line enable flag | |
| 34. MT: missing fseek before write eof | |
| 35. MT: displayed characters only 7b wide instead of 8b | |
| 36. CPU: EOD 20000 used by diagnostic (EM change is NOP) | |
| 37. CPU: SKD sets all 24b of X, not just exponent | |
| 38. CPU: reset should not clear A, B, X |
