Hello, acidrain
I suggest this layout design
http://sblive.narod.ru/ZX-Spectrum/MembraneKeyboard/PA-Keyb2.gif
The letter and number keys simply slide to the side. It turns out straight
original keyboard after all :D
ZY You can stuff a flop guide or
player%) (if, of course, someone wants to compact the spec board into it ;) )
Hello fan
fan> I suggest this layout design
What function does the mouse button perform?
Hello, CHRV
CHR> What is the function of the mouse key?
I have no idea, these are leftovers from the design of the dog keyboard. I don't know what
It's better to assign it there.
Hello Costa
Dear one with a click and everything!
And a numpad wouldn't hurt!
Hello Sonic
Look at http://www.speccy.org/trastero/cosas/droy/imar3/imar3_e.htm, she

Damn, COOL!!!!!! New version of the cartridge with software (under the dog!) for
collecting images of cartridges (with a menu!) from snapshots !!!!!!!!
ZY Interface II design is described in Spanish only
http://www.speccy.org/trastero/cosas/droy/interface2/interface2_s.htm
IMHO, it should be moved to a separate topic.
Hello fan
There is an idea: convert a regular PC keyboard into a ZX by soldering the cable
directly to the contacts connecting the film and the circuit. The mismatch problem
designations on the keys can be solved by changing the tables in the ROM, and
processing software that does not use ROM. STS, for example, is not needed at all
will redo it, because it uses keyboard polling from ROM.

and an iron plate. The keyboard is from 1997.
In addition, there are 11 wires coming from the ZX keyboard (if I haven’t forgotten something), and for

this piece of junk tends to break off at the most interesting place in the toy....
It would be better if they came up with (suggested) a way to apply the Spectrum layout on PC

Somewhere here there was already a reasonable proposal for a simple conversion of the PC keyboard into
ZX: just replace the bottom “signet” with a homemade one, with your own
wiring the contacts, and put the rest of the pussy films on top of it. And
no controllers needed! :) I wonder if this option will work?
Hello, do_se
do_> ...there is no signet there! three layers of films with a deposited matrix and

It is precisely the bottom film with the iron plate that is replaced with its own signet :) A
there are 8 half-rows of wires + 5 keys in a half-row = 13 wires :) With extended
There are indeed some problems with the keys.
Technically, if you really need extended keys, then the easiest way is to use
PC keyboard + controller combination. Due to the lack of a sane method of application
ZX markings on the buttons, you will have to use VASIK-128 :)
Hello, do_se
It is also very easy to remake PC keyboards that instead of films and
rubber bands have free-standing buttons with normally open contacts
Such keyboards always have a clear click.
So we simply cut off unnecessary paths and connect them with wiring as we need
necessary. The issue of extended buttons is also solved by logic.
I saw the same keyboard device on SUBOR consoles (Dendy with
keyboard)

They can be solved quite reliably with a flat cable.

Hello fan

You're probably pressing the quota button on the wrong message.
Well, even more so, everything can be fixed. Just edit your message and write it in with your pens
the right nickname.
Hello fan
fan> Somehow I have the wrong names in my quotes %)
For an alien this is forgivable :)
Hello, ewgeny7
Well then the question is removed until complete assimilation :v2_lol:
Hello Costa
Yes, I kind of used the Quote from the highlighted one, although what can I take from the planet)
Probably the extra quotes were somehow strangely erased, but the nickname was left, idk. in short...

It’s strange that the idea of a Spectrum cartridge didn’t convince anyone, because it
is cut according to the standard scheme (like a branded cartridge), well, straight to
Any speck without any perversions, and even all the necessary software is given.
I don't understand anything:

Well, why didn’t I tell you, everyone is just silent as always.
It still seems to me that the device is not very useful, although I still took note.
:v2_wink2:
Firstly, you need a large ROM, but you can write prog there, but not at all
a lot and for example I can’t stand all sorts of magic and snaps. For me it’s better
normal file-by-file loading and what about programs with additional downloads or
all sorts of saves there. Do you have any interesting ideas for using this
cartridge?
Hello Costa
Use for its intended purpose ;) For all previously known options
The cartridges were a bit scary, and the games required manual adaptation. And this one
option may well become an alternative to downloading from a “turbo audio” source for
almost any spec (especially if there is some semblance of a system
connector). Additional loadings (as with “turbo audio”) in flight...
Hello Costa
Cos> and I can’t stand all sorts of magic and snaps
Snap Snap is different! Here [http://zxpilot.vladivostok.ru/games.shtml] I am
I posted snapshots for my emulator.
These are ordinary sna48 files, only there is a header of several tens of bytes,
necessary for PalmOS (it can be easily cut off, and you can find out the length by subtracting the length
standard SNA48 from Palm).
So, each snap was made using the following method:
1. Take the “branded” TZX of the game you are interested in.
2. During loading, the debugger sets a breakpoint at the end of the loading
last byte of the game.
3. A microscopic subroutine is placed two bytes below the top of the stack
waiting for any key to be pressed followed by an unconditional transition to
breakpoint address from step 2.
4. PC is rearranged to the address of the beginning of the subroutine from step 3
5. SNA48 is saved.
The snapshot obtained in this way has a branded splash screen that can be
contemplate before pressing any key, not a single byte of the code itself is touched
programs, only 11 (in my case) bytes of the stack are corrupted.
Why not load just such snapshots from cartridges???
True, this method is only suitable for games without additional loading levels....
P.S. Now I went to my page and discovered that for some reason the counters
reset... There were several hundred downloads for each game...

Then I don't understand what difference it really makes what it outputs. Or maybe
Is it possible that in BASIC-128 LEN will be issued instead of 0?
Hello fan

The fact is that on machines where there is no BASIC 128, this key will not produce
the number is 0, and the token is LEN.

It will not output anything at all - in this case, the NumPad will not

By the way, if anyone doesn’t understand, NumPad polling is done via a two-wire line in
sequential code.
The polling time is quite long (I don’t remember the value now - if necessary I can
clarify).
So in programs it will be quite slow.
Hello icebear
ice> Then I don't understand what difference it really makes what it outputs. Or
ice> maybe in BASIC-128 LEN will be issued instead of 0?
In Basic-128, this keyboard operates in two modes - digital or control.
In control mode, pressing the 0 key produces token LEN, which in the editor
executes the command "delete all characters in the line from the current position to the beginning
lines".
There is no way to enter this code from the standard keyboard field in Basic128 mode.
In digital mode, each key produces a code corresponding to its marking (0 ->
#30).
