| 21. | These models have 2 additional data bus wires to the EEC-IV diagnostic connector ).
|
| 22. | The SDRAMs used are 16 bits wide and have separate address and data buses.
|
| 23. | The backplane served as the address bus and the ribbon cable as the data bus.
|
| 24. | The only way out is to board the data bus and help fix the mess.
|
| 25. | Use of the data bus is intricate and thus requires a complex DRAM controller circuit.
|
| 26. | Buses don't need to be just the traditional address or data bus directly linked pins.
|
| 27. | Data bus systems aren't nearly as sexy as superfast processors or hulking great hard drives.
|
| 28. | The company moved from a proprietary data bus architecture in favor of IBM's PRISM line.
|
| 29. | A 16-bit data bus also required twice as many memory chips as an 8-bit one.
|
| 30. | I / O operations can slow memory access if the address and data buses are shared.
