http://www.user.dccnet.com/wrigter/index_files/ZXKBDv3.htm This is going to be my next hardware project. I've got the chips coming and a donor BBC micro keyboard that will be dremelled any time now :D I'm going to miss out the IO port but keep the joystick connector. Edge connector sockets are hard...

Are you sure this is your 1st C program? I think you're pulling our legs ;P

Congrats - this is an awesome achievement!



P.S. I'll be nicking your code later

Can't be done. You could get many instructions that make sense. F'r instance is that a5 immediately behind PC an AND L, the end of an AND IXL, or the operand of ADD A,NN? Are you thinking history? Reverse execution? Whatever you need the past for I think there would have to be - like Andy suggested ...

Just what I was looking for!

Hi Xav There's some great stuff on your(?) site. I have a lot of trouble navigating it though - I ought to learn better French :) I like the look of these keyboards. I will definately be getting a replacement membrane or two but I would also really like to have an expansion port add-on like the memo...

/me takes a bow my pleasure! I'm working on adding symbol file support. I use telemark (tasm) and that will be the first format to add. As I haven't used other assemblers on the '81 I'd like a sample of symbol files from other projects if people wouldn't mind. I'm not going for comprehensive support...

In a new debugger It will be great to have separate DUMP Memory windows, windows that one can set position and contents (memory area) so the debugger can refresh those windows on BREAKPOINTS and on the STEP by STEP operation, ideally the feature of set "memory casting" I mean bit, bytes, word, stri...

Would you like mayonnaise on that, sir? :lol: Seriously, Regard debugger window, We WANT the No$cash debugger... This is what inspired me. no$ is a good emu, but it feels 'unfinished' And the direct access of VB81 ... in a directory. Could you explain this a little more please? The Xtender grafic sc...

If there's interest then I could rewrite this in portable c++ and make it a command-line app.

Shouldn't take long, I already have the bones of a similar app.

[edit] pipped to the post.

I have something that I wrote, it's a .net application so windows only I'm afraid

Having seen paintyOne I'm inspired to re-write it in JS...

Anyway - you can have a copy of this if it sounds like it would suit you.
