ND-120/CX¶
The ND-100 line reduced to a single chip, code-named Delilah.
| Introduced | 1985-87 [?] |
| Type | Base machine |
| Word length | 16-bit |
| Needs a host? | No, runs on its own |
| Replaced | ND-110/CX |
| Replaced by | ND-125/CX (~1994) |
| Survivors | Not recorded |
The short version¶
A complete redesign of the ND-110 onto one large LSI gate array called Delilah. About 1.9 times the speed of an ND-110/CX, with minor microcode changes and no change at all to the instruction set. It was nearly sold as the ND-1000, to mark the technology change the way the ND-500 to ND-5000 rename did. The name is a joke: the 32-bit machine was Samson, so the 16-bit chip that fed it was Delilah - and ND's internal documentation for the chip carries a drawing of a grinning woman with hair in her clenched fist.
Specification¶
| Item | Value |
|---|---|
| CPU | One LSI gate array (Delilah) |
| Speed | About 1.9 times an ND-110/CX |
| Instruction set | Unchanged. Minor microcode changes only |
| On-board memory | 2 MB to 6 MB |
| Second role | I/O processor for the ND-5700 and ND-5800 |
| Nearly named | ND-1000 |
What was new¶
- The whole CPU on one chip.
- The last real step in the 16-bit line's evolution.
Configurations¶
| Machine | What differs |
|---|---|
| ND-125/CX | Same CPU, faster and larger on-board memory |
