Hi,

I got a NC100 from eBay, which was supposed to be faulty, which was great as I like repairing computers.

But after looking atbthe circuit board, I noticed that someone had removed the ROM chip and been a little hand-fisted in inserting, crushing a pin on the ROM, once the pin was straightened and the ROM inserted in the socket the NC100 started up and is working okay.

So I have a working NC100, what can I do with it?
Regards,
Derek

That's the right attitude. Buy first, then think about what you can do with it ;-)

Looking at my "retro" cabinet, that happens pretty often to me too.

Start programming for it... There is not too much software for the machine so there is a lot of places you can begin.
I tried my hand at a monitor/debugger for the NC100 (https://github.com/JimmyDansbo/NC100Monitor), but it probably needs a complete rewrite to be any kind of useful.

Well , I like repairing retro computers, they are usually sold on to people who like to play old games 

I used also like programming computers in assbler, mainly Sinclair, so Z80 programming is fairly straight forward.

Is there an sssembler for the NC100?

Derek

I use RASM, it is not specifically for the NC100, but it is for the Z80.

There's actually an assembler built directly into the nc100's BBC Basic, which in some respects is probably easier to deal with, although it's also easy to lose your work when you crash the unit and have to do a hard reset...

Hi

Thank you for the information, I just realised this myself.

I looked at the manual in the link, looks similiar to the Z88 BBC Basic and I done a bit of assembler on a BBC Micro

Derek
