MESS supports the emulation of the nc200 with a “cartridge” (cart) device, for carts in .crd and .card format, as it was for the nc100. Additionally, also a “floppydisk” (flop) device is emulated, for disk images in .dsk, .ima, .img and .ufi format.
Also notice that the “printer” (prin) and the “serial” (serl) port are emulated as well.
Printer emulation is working. All data is saved out to a file on the host filesystem. The data is not processed in any way, so the file will contain the raw bytes output to the printer port.
Same as NC100.
Not working. I am trying to find out the details of the disc interface by looking at lots of disassemblies!
This system requires full keyboard emulation to work correctly. At startup, full keyboard emulation mode is enabled by default. Whilst in full keyboard emulation mode, some key associated functionality may be disabled (like the ESC key for EXIT). The keyboard emulation mode is toggled using the “Scroll Lock” key (by default).
The emulation is reasonably accurate. There are no documents about the hardware of the NC200. Originally Cliff Lawson published details but these have been lost when his WWW site went down. Since then he has been unable to write up the details of the hardware (Cliff is a very busy man).
So I have worked out much of the NC200 hardware by disassembling the ROM and I have also had much help from Russel Marks.
The Amstrad NC200 Notebook computer is a portable computer.
This system has a fold-down LCD screen, nice keyboard and disc drive. (The disc format is 720k PC Double Density DOS compatible).
The memory is protected by a lithium battery which is charged when the computer is connected to a mains supply.
PCMCIA RAM cards can be used to store programs and documents.
The computer has a built in wordprocessor, BBC Basic, Serial Terminal, Calculator, Diary and more. The whole system is a personal organiser with lots of extras.
The NC200, was the last model of the NC series which was comprised of the NC 100 and NC 150.
It was a very much smarter, more professional design, with a larger fold-out screen, offering 80 columns by 16 lines, a built-in 3” inch, 720 kilobyte floppy disk drive for storage, but at a heftier price tag of £329.
It also had a spreadsheet, which the NC100 did not, as well as twice as much built-in memory at 128 kilobytes.
