ND-110/CX¶
The fast ND-110, known inside ND as RASK. Also the I/O processor for ND-500 systems.
| Introduced | 1986 |
| Type | Configuration of ND-110 |
| Word length | 16-bit |
| Needs a host? | No, runs on its own |
| Replaced | ND-100/CX |
| Replaced by | ND-120/CX (1987) |
| Survivors | Not separately recorded |
The short version¶
A faster ND-110 - between 1.5 and 3.5 times the base machine - introduced in 1986 as part of a general refresh of the ND-100 range that also brought the ND-110 Compact and Satellite. Existing systems could be upgraded. Beyond being a machine in its own right, it became the I/O processor inside ND-500 systems, doing the operating system and input/output for the 32-bit CPU.
Specification¶
| Item | Value |
|---|---|
| CPU | ND-110 with the CX microcode. Three new integrated circuits cut the device count from 365 to 228 |
| Speed | 1.5 to 3.5 times an ND-110 |
| Cache | Increased over the ND-110 |
| Power | 40 percent less than the machine it replaced |
| Instruction set | The CX additions - decimal, MOVEW, TSET, RDUS, segment changes |
| Second role | Used as the I/O processor in ND-500 systems, and in the ND-5400 and ND-5500 |
What was new¶
- Device count almost halved, onto a single module.
- Became the standard front-end for the 32-bit machines, not just a machine of its own.
