| 1. RP: drive clear does not clear RPDA. | |
| 2. TU: default formatter must be TM03. | |
| 3. SBI: drive 'letter' is actually a 1-based number. | |
| 4. MBA: drive register reads return SR<31:16> as high word. | |
| 5. UBA: DMA addresses must be masked to Unibus width (18b). | |
| 6. HK: thread used multiple times if SEEK is followed by NOP or DCLR. | |
| 7. HK: only DCLR clears ATA. | |
| 8. MEM: MS780E size declaration off-by-1. | |
| 9. MEM: MS780E array start off by >> 4. | |
| 10. MEM: CSR-C register write logic incorrect. | |
| 11. CIS: CMPP3/CMPP4 using wrong arguments to ReadDstr. | |
| 12. CPU, OCTA: CVTfi with integer overflow not setting trap if PSW<iv> = 1. | |
| 13. STDDEV: read of ICR was missing the call parameter. | |
| 14. ACBD/G: testing wrong operand register to get limit sign. | |
| 15. CPU: faults not clearing PSL<tp>. | |
| 16. ADAWI: register mode implemented incorrectly. | |
| 17. MOVTC: condition codes not preserved through page fault. | |
| 18. MOVTUC: condition codes not preserved through page fault. | |
| 19. MOVTUC: escape tested against untranslated rather than translated character. | |
| 20. CVTPT: condition code and decimal overflow calculation incorrect. | |
| 21. CVTPS: condition code and decimal overflow calculation incorrect. | |
| 22. CVTPL: if destination is register, result is stored after register updates. | |
| 23. CVTPL: integer overflow set <C> rather than <V>. | |
| 24. all decimal string: 11/780 does not validate characters in decimal strings. | |
| 25. EDITPC: condition codes not preserved through page fault. | |
| 26. EDITPC EO$INSERT: inserts sign instead of fill. | |
| 27. EDITPC EO$BLANK_ZERO: address off by one. | |
| 28. EDITPC EO$BLANK_ZERO: not testing for <C> set. | |
| 29. EDITPC EO$LOAD_PLUS: not skipping character if test fails. | |
| 30. EDITPC EO$LOAD_MINUS: not skipping character if test fails. | |
| 31. Compatibility mode: SXT not implemented. | |
| 32. Compatibility mode: XOR operands fetched in wrong order. | |
| 33. MNEGH: condition codes set from original sign. | |
| 34. MNEGH: <C> not cleared. | |
| 35. H_floating quad precision integer routines (add, inc, neg): carry propagation incorrect. | |
| 36. H_floating packup routines: test for zero used exponent not fraction. | |
| 37. MULH: carries out of floating accumulator lost. | |
| 38. DIVH: stores wrong operand as result. | |
| 39. POLYF/D/G: truncation after add not needed. | |
| 40. POLYF/D/G: early SRM requires truncation to 31b/63b, not 32b/64b. | |
| 41. POLYF/D/G/H: exits too early if argument is zero. | |
| 42. POLYD/G/H: calculates address of residual pointer result incorrectly. | |
| 43. POLYD/G: performs single precision rather than double precision multiply. | |
| 44. POLYH: fails to truncate intermediate result from 128b to 127b. | |
| 45. POLYF/D/G/H: internal add routine must test fraction rather than exponent to | |
| detect zero, POLYx can create "denormalized" intermediate result. | |
| 46. EMODH: concatenate 16b of extension operand instead of 15b. | |
| 47. Specifier flows: modify flows testing for read access rather than write access. | |
| 48. Quad/octa writes: wrong address reported on faulting cross-page writes. | |
| 49. Memory management: 11/780 implements access control test on first level PTE's. | |
| 50. LDPCTX: 11/780 implements mbz tests on PCB fields. | |
| 51. LDPCTX/MTPR: 11/780 validity checks PCBB, SCBB, SBR, SLR, P0BR, P0LR, P1BR, P1LR. | |
| 52. TMR: tmr_inc not updated in standard (100Hz) mode. | |
