 +
Function+P - print
 +
Function+S - Serial
 +
Function+A - Alarm

Function+D - Address book
 +
Function+F - File manager (for disk)
 +
  (on menu E Edit, D delete, D delete marked files, R (rename), C (copy files to memory), N (make new directory), F (format disk), SHIFT+CONTROL+H to toggle display of hidden files)
 +
Function+G - games

 +
Function+Z - time zone manager
 +
Function+C - Calendar
 +
Function+N - new document (wordprocessing)
 +
Function+X - change file display options (from main menu)
 +
 +
Holding [Function][Control][Symbol] and then pressing the power key will cause the machine's self test mode to begin with the general test and then continue with the disc drive test (a disc must be in the drive for the test to operate!).
 +
 +
==NC200 Disc access==
 +
 +
To format a disc go to file manager (Function+F, Press menu and select F)
 +
Discs are formatted to double density, 80 track, 2 sides with FAT filesystem. They can be read directly by a PC.
 +
There is 712K free. A directory called "NOTEBOOK" is created by default.
 +
 +
The disc interface is turned off if there is no activity for a few seconds, or if it is not required by the application. When it does this the drive seeks to track 0.
 +
 +
By default, the NC200 will work from RAM. All files are read/written to it's internal memory. This includes from BASIC when SAVE and LOAD and *. (list directory)
 +
are used.
 +
 +
Reading files from Disk:
 +
 +
If you wish to transfer files to memory to use them, you need to go to the file manager (Function+F, select each file with space, press menu and then select  "copy marked files to memory").
 +
The files will be read from disc and read into RAM.
 +
 +
NOTE:
 +
1. Any file can be read from disc and transfered to RAM. The file is then visible in the list of documents. All files are transfered this way including binary files.
 +
2. You can load a document from disc into the word processor. However, it actually transfers the file from disc and makes a RAM file. It then loads the RAM file.
 +
This means that if you try to load a large document you will run out of RAM.
 +
3. Using BASIC, there is approx 40K free RAM (using LOMEM and HIMEM variables to find lower and upper limit respectively) on a NC200 machine without RAM card.
 +
 +
Writing files to Disk:
 +
 +
If you wish to transfer files to disc, you need to press Green to go to the list of documents. Press space and highlight each document you want to copy, press menu and then select "Copy marked files to disk"). The files will be read from RAM and written to disk.
 +
 +
== BASIC program transfer ==
 +
 +
To transfer a BASIC program *to* the NC computer you will need it to be stored as ASCII and not in it's native tokenized binary form.
 +
You can save a BASIC program to RAM in it's tokenized form, but it will not display in either the wordprocessor OR the spreadsheet document list.
 +
Therefore you can't copy it on/off the NC this way.
 +
 +
For NC200 you can use the floppy drive and use the file manager to copy files from the disc into ram.
 +
For all NC computers you can use the memory card OR serial interface to transfer files.
 +
 +
To transfer a BASIC program *from* the NC computer will need to convert it to ASCII.
 +
Do this with
 +
 +
*SPOOL <filename>
 +
LIST
 +
*SPOOL
 +
 +
The ASCII version of the file will now be in the NC computers ram.
 +
 +
For NC200, you now need to list all wordprocessor documents and then you can copy the ascii file to disc.
 +
For all NC computers you can also use the serial interface.
 +
 +
To load a BASIC program as ASCII do this:
 +
*EXEC <filename>
 +
 +
This will load the basic program and you can then LIST it and RUN it.

The following text was copied in part from the English Wikipedia article.

Amstrad NC100

The Amstrad NC Series was a series of A4-sized, portable Z80-based computers, released by Amstrad in 1992-1993. All models featured 64 or 128 KB of RAM, the Protext word processor, various organiser-like facilities (diary, address book and time manager), a simple calculator, and a version of BBC Basic.

The screen of the first two models (NC100 and NC150) was small, eight rows by 80 columns, and not backlit, but this let the NC100/150 run for up to 20 hours on four standard AA cell batteries. There was an RS232 serial port, a parallel port for connecting a printer, and a PC card socket, by means of which the computer's memory could be expanded up to 1 MB.

Design

The NC100 was designed to be a portable computer which was simple to use. That was the brief given by Sir Alan Sugar (then chairman of Amstrad) to his design staff. The NC100 project was internally referred to as Alan's "Baby" and Alan Sugar himself tested the machine for usability during the design phase. The specifications for the computer were not considered important - as long as it could serve its purpose.

The simple to use features of the NC100 come from the software which is included on the internal ROM chip. The Word processor and other applications have been written with a computer novice in mind - although experienced users can find and use a large array of more complicated features.

Alan Sugar actually wrote the first chapter of the NC100's user manual in order to show that even he could use it.

The design also included terminal emulation and XMODEM file transfer software which enabled the NC100 to communicate through dial-up analogue modems. UK tech journalist Sue Schofield used one to upload a review of the NC100 directly into the online filing computer of the Independent newspaper in 1993. The review was written on the machine, and transferred from it over a 300 baud modem.

NC200

An upgraded version, the NC200, appeared in late 1993, featuring a 3.5" floppy disk drive able to read/write MS-DOS-formatted double density disks, 128 KB RAM, some extra software - most notably a spreadsheet and three Tetris-like games - and a larger, backlit screen. However, this change required much greater power use, using 5 C cell batteries. The disk drive could only be used at near full-charge, which meant that it could only be used a few hours after putting in new batteries. However, the laptop could function for considerably longer than this without using the disk drive. The backlight can be manually toggled off to save power by pressing the Control and Caps Lock keys at the same time.

Holding [Function][Control][Symbol] and then pressing the power key will cause the machine's self test mode to begin with the general test and then continue with the disc drive test (a disc must be in the drive for the test to operate!).

NC200 Disc access

To format a disc go to file manager (Function+F, Press menu and select F) Discs are formatted to double density, 80 track, 2 sides with FAT filesystem. They can be read directly by a PC. There is 712K free. A directory called "NOTEBOOK" is created by default.

The disc interface is turned off if there is no activity for a few seconds, or if it is not required by the application. When it does this the drive seeks to track 0.

By default, the NC200 will work from RAM. All files are read/written to it's internal memory. This includes from BASIC when SAVE and LOAD and *. (list directory) are used.

Reading files from Disk:

If you wish to transfer files to memory to use them, you need to go to the file manager (Function+F, select each file with space, press menu and then select "copy marked files to memory"). The files will be read from disc and read into RAM.

NOTE: 1. Any file can be read from disc and transfered to RAM. The file is then visible in the list of documents. All files are transfered this way including binary files. 2. You can load a document from disc into the word processor. However, it actually transfers the file from disc and makes a RAM file. It then loads the RAM file. This means that if you try to load a large document you will run out of RAM. 3. Using BASIC, there is approx 40K free RAM (using LOMEM and HIMEM variables to find lower and upper limit respectively) on a NC200 machine without RAM card.

Writing files to Disk:

If you wish to transfer files to disc, you need to press Green to go to the list of documents. Press space and highlight each document you want to copy, press menu and then select "Copy marked files to disk"). The files will be read from RAM and written to disk.

BASIC program transfer

To transfer a BASIC program *to* the NC computer you will need it to be stored as ASCII and not in it's native tokenized binary form. You can save a BASIC program to RAM in it's tokenized form, but it will not display in either the wordprocessor OR the spreadsheet document list. Therefore you can't copy it on/off the NC this way.

For NC200 you can use the floppy drive and use the file manager to copy files from the disc into ram. For all NC computers you can use the memory card OR serial interface to transfer files.

To transfer a BASIC program *from* the NC computer will need to convert it to ASCII. Do this with 

*SPOOL <filename>
LIST
*SPOOL

The ASCII version of the file will now be in the NC computers ram.

For NC200, you now need to list all wordprocessor documents and then you can copy the ascii file to disc. For all NC computers you can also use the serial interface.

To load a BASIC program as ASCII do this: 

*EXEC <filename>

This will load the basic program and you can then LIST it and RUN it.

Serial Terminal

NC100:

Press FUNCTION+S to enter Serial terminal. You can press MENU to change the settings. Here characters that are received will be shown immediatly.

If you want to transfer a file, the best method is to use XMODEM. First you will need to create a dummy document. (Press FUNCTION + Left Arrow, then Left Arrow, enter name of doc, and then ESC to quit).

Now if you go to view documents, you can press MENU. From here you can choose .... and do a xmodem receive document.

NC200:

Press FUNCTION+S to enter Serial terminal. From here you can press MENU, and choose to do a xmodem receive or send or to setup the terminal. If you press RETURN instead of MENU, you will enter the terminal like the NC100.

XMODEM transfer

NC100: 

1. Enter wordprocessor.
2. Start a new document
3. Quit wordprocessor
4. Go to list documents.
5. Press MENU key
6. Here you can navigate the menu to find "XMODEM receive document".
7. Start XMODEM send on PC.

NC200: 

1. Enter serial/terminal program.
2. Press MENU
3. Press R (for XMODEM receive)
4. Start XMODEM send on PC.

  • The NC's and Nakajimas

  • Closeup of Nakajima ES-210

These computers appear to use the same hardware as the NC100, except a NEC V20 (8086 compatible CPU) is used in place of the Z80.
