| The KS10 uses the PDP-11 Unibus for its I/O, via adapters. While | |
| nominally four adapters are supported, in practice only 1 and 3 | |
| are implemented. The disks are placed on adapter 1, the rest of | |
| the I/O devices on adapter 3. | |
| In theory, we should maintain completely separate Unibuses, with | |
| distinct PI systems. In practice, this simulator has so few devices | |
| that we can get away with a single PI system, masking for which | |
| devices are on adapter 1, and which on adapter 3. The Unibus | |
| implementation is modeled on the Qbus in the PDP-11 simulator and | |
| is described there. | |
| The I/O subsystem is programmed by I/O instructions which create | |
| Unibus operations (read, read pause, write, write byte). DMA is | |
| the responsibility of the I/O device simulators, which also implement | |
| Unibus to physical memory mapping. | |
| The priority interrupt subsystem (and other privileged functions) | |
| is programmed by I/O instructions with internal devices codes | |
| (opcodes 700-702). These are dispatched here, although many are | |
| handled in the memory management unit or elsewhere. | |
| The ITS instructions are significantly different from the TOPS-10/20 | |
| instructions. They do not use the extended address calculation but | |
| instead provide instruction variants (Q for Unibus adapter 1, I for | |
| Unibus adapter 3) which insert the Unibus adapter number into the | |
| effective address. | |
