Nice music, brave design ...
Great work!

And now the important question: How can I get my Ramcart ?!
\twh
Unfortunately, we aren't able to manufacture this RAMcart per order.
So, you have to ask some Atari hardware maker in your neighbourhood.

S/XEGS RAMCART 128KB by C.P.U.
Info and complete production documentation:
http://raster.infos.cz/atari/hw/ramcart/ramcart.htm
Enjoy it!

Our S/XEGS RAMcart has read_olny/read&write hand switch. But this switch has to be set to "read_only" state if cart is enabled and Atari is turned on (or if reset key is pressed), because initial OS ROM routines overwrite some parts of cart memory otherwise. (Cart memory is mapped instead of standard Atari RAM and OS routines does the clearing of screen memory etc.)
But, for example, game (or other program) can show some request message like "Please, permit the RAMcart WRITE now.". (Also our patched version of DOS II+ does it - red background color appears if write operation to ramdisk is required.) After the RAMcart write operation there is recommended to restore "read only" state of course.

In Chile, twenty years ago some guys develop (or copy) this memory card system. Is very primitive but are the basis of the project RamCart.
It's interesting, I haven't seen it never.
But it isn't the same hw, It has 32KB memory only, so Commando 128KB and/or other 64 or 128KB SXEGS games can't be working with it.
Also it hasn't sw switchable capability.
Ufff...
The chips are erased, i have some of this cartridges and all come with erased chips.I think I recognise chips used there exactly. :-)
You can see first old prototype of our RAMcart which hasn't sw switchable feature. But it has 128KB SRAM already and that's why there is some "bigger" chips in our cart (more banks, more complicated PCB). Also some more features it has had.

(big 128 KB Memory chip is on other bottom side
)Our S/XEGS RAMcart is much more different, fortunately.
PS : Luck with the competition !Thanks.

but what is the difference to AtariMax Cart?
* 128 KB SRAM with 3V battery - years of lifetime (!), unlimited number of overwriting (!), no block-save necessity (!).
* Full XEGS cartridge bank switching compatibility (!). All the great 32/64/128KB XEGS cartridge games is possible to play on Atari with this one RAMcart. (Commando, TowerToppler, etc. .... without need of ANY modifications)
* Usable for standard 16KB cartridge games, also most of classic 8KB cartridge games are working.
* SXEGS switchable mode.
* Read only mode for cart memory protection.
* XEGS RAMcart File Feeder software for easy loading of cart dump files.
* with special DOS it can works also as ramdisk (D8: device with cca 120KB, battery keeps its content)
* new Creaxin1 software for making of programs/games packages.
* components' price cca 250 Kc (8 EUR)

And here's an old tune (a conversion from an earlier thread about pokey music)
some changes by mux
enjoy_mux_exp15.zip
Wow. Very nice! -
...This brings the sources up to date
with those I found in A800WinPLus B7, however I haven't updated
any of the 'about' information yet.
Yes, Mark, please, update the about info strings we identify old and current DLLs' versions.
void __declspec(dllexport) Pokey_About(char** name, char** author, char** description ) { *name = (char*)"POKEY Chip Simulator, V2.3 (A800 1.2.4)"; *author = (char*)"Ron Fries, Atari800 emulator developer team, http://atari800.sourceforge.net"; *description = (char*)"Stripped down version for Pokey sound generation only by C.P.U. 2003"; } void __declspec(dllexport) C6502_About(char** name, char** author, char** description ) { *name = (char*)"CPU 6502 emulation, 1.2.4"; *author = (char*)"Atari800 emulator developer team, http://atari800.sourceforge.net"; *description = (char*)"Stripped down version for instructions execution only by C.P.U. 2003"; }And please, let me know, when new DLLs versions will be finished - I will publish them on SA_LIBRARY website. Thanks.

Yes, yes. Emkay, your G2F pictures are really great!
I like them. -
Hot news
22.8.2005 ... RMT 1.21 tracker with enhanced mouse control etc.
You can get it from the RMT website.
Changes in RMT 1.21
-------------------
- Enhanced mouse control:
* Set cursor position in trackedit area, songedit area,
instrument parameters / envelope / table area, info / speed area.
* Octave selection by mouse (click to "OCTAVE x-y" text).
* Volume selection by mouse (click to "VOLUME x" text).
(Also you can turn on/off "respect volume" option there.)
* Instrument selection by mouse (click to "XX: instrument name" text).
* Envelope GO/LEN parameter setting area (click to mouse L/R button).
* Table GO/LEN parameter setting area (click to mouse L/R button).
(Areas' locations - see the screenshots.)
- New hotkeys:
SongEdit:
* Enter ... Exit from SongEdit section.
* Home ... Move cursor to first songline.
* End ... Move cursor to last songline.
* PageUp ... Move cursor 4 songlines up.
* PageDown ... Move cursor 4 songlines down.
- New option in Config dialog (menu View - Configuration):
* Don't use hardware soundbuffer
(default is off).
(Maybe it could help if you have some system sound related problems.)
-
Let's say I want to change effect/volume/whatever walue. Now (in v.1.1.9 IIRC) I have to use certain key x times to put the cursor in desired place. Can't it be done with a mouse?Hmmm... Ok. I will thinking about it.
It may sound stupid but lack of this feature refrains me from using RMT.Oh, It's a pity. Ok. Please, keep your patience (and compose musics in other Atari trackers meanwhile.)
-
thanks for your great efford put into RMT... hope raster has a lot of input (and of course others...not just analmux and you...)
No, I haven't other inputs. I think RMT is now in stable and usable state and I hope no only me will use it for making music/sounds for games, demos, etc...
And I want send word to all critic men:
Maybe RMT isn't ideal (nobody is perfect
) and doesn't exploit all POKEY capabilities ... So, anyone can make better tracker with features at pleasure! 
But, personally, I believe in music capabilities of good musicians more than sound capabilities of POKEY.
what about stressing now TMC2.0???? really? Jaskier would be glad...
Ehm...
-
The actual netlists and circuits have been recovered, creating an fpga of the chip is feasible. The disk images are PC test disks, not the actual 8bit disks, I will post those shortly though what use they are without others have the chip...
Curt
It's great.
It would be cool to hear the AMY chip sounds/musics!
Wow.

......I started thinking but when you have a table of notes starting with '15' this means that the melody will be played 21 semitones higher. Nice idea. But ... you have to see to the parameter TABLE TYPE, which is set to 1 => above the '15' you can see the info text "TABLE OF FREQS", no "TABLE OF NOTES".
So, hexa value '15' in this case means that decimal value 21 will be added to frequence, no shifting about 21 semitones.
......messing more with TABLES OF NOTES function in 15kHz mode I've noticed that this IS an RMT bug and has nothing to do with the effect I described in red{@RASTER: I hope you pick up this discussion.}
I hope there isn't bug in RMT.

What are all the known devices that connect to the Joystick ports that are not joysticks/paddle/trackballs/etc.
Interface MULTIJOY8 (16)
This easy multiplayer interface allows connect up to 8 joysticks to one Atari XE/XL computer via both joystick ports (MultiJoy16 up to 16 joysticks.)

Yes, IK+ is the great project!!!
still do not know why it needs 128kb instead of 64k but well...This Atari version must use a lot of complicated techniques for three players colors (sophisticated PMG overlaying / line positioning / several charmaps), and It needs a lot of memory.
But the result is cool!
-
That was my apprehension. It's not only a command for the update speed. OK.
Yes. Destination portamento frequency is taken from actual note frequency every time when command 5 XY is used (and portamento level and speed is set up by XY). And if 5 00 is used, then beginning_portamento_frq = destination_portamento_frq = actual_frequency.
Yes, it works in this way.

(Portamento on)Setting the command of
533333333
100000000
811111111
works for a special way.
Trying to change the envelop is not giving the awaited results.
Setting the command new at the envelop
5333353333
1000010000
8111181111
Using this, gives a full "swap over" sounding.
In theory the first command and the second command should result almost in the same sounding, but it doesn't.
You have been used there command 5 18 two times, and before second command 5 18 there is 4 times command 3 01 which transpose up base note about 4 halftones.
So, if original portamento destination note was for example C-2 (frq 121), then you change it by second 5 18 command to note E-2 (frq 96), that's why it must sounding differently. :wink:
-
That's how to use it...
For me it seems to be a separated controller. So what are the limitations of that controller? Especially at the deeper notes, it seems to stop somewhere. And, if setting the notation value to high (or to low) will turn the note off, instead of changing the portamento ...
Well... if its my mistake, you may show the corrected handling in the tunes bass-tone?
I don't understand your question. Portamento is effect for slower transformation from one note to other.
So, frequency is shifted up or down to new note (i.e. shifting will stop on frequency of destination note).
For example: Note C-1 with instrument effect 5 00 => play note C-1 (frq 243) and init portamento to value 243.
Now Note C-2 with instrument effect 5 11 and portamento switch turn on => every 1/50 sec will frequency shifted up (from beginning value 243) to destination frequency value C-2 (121). That's all.
Or you can see the example songs/examples/likea64.rmt, there is portamento used.

@raster
What are the limitations of portamento in RMT exactly?
I did put it to the limits, but it seems not "fast" enough, when using deep notes...
Please, see the manual.
Envelope command (COMMAND parameter)
...
5 Set up portamento speed $X, step $Y (each $X vbi will be "volatile portamento frequency" shifted up or down by $Y value in a direction of actual frequency). If $XY=$00, then set current frequency directly to volatile portamento frequency.

Oh, very nice picture.

The problem is: If emkay would have done this tune, no one would have liked it.
You're good joker, Emkay.

If we put 2 pokeys into a cart and use A7 to select between the two... one at $d500 and the other at $d580, with a stereo jack...It should be easy to do for plug and play
Can I ask why there is used A7 ($d500/$d580) to select first or second pokey?
Why you don't use A4 so that there was first pokey at $d500 and second at $d510. It would be more similar to standard ($d200 for standard built-in pokey and 16 addresses below at $d210 is established location for second built-in pokey).

An Idea someone?
in Atari 8-Bit Computers
Posted
Yes, It's interesting question...
Musics in older (preview) version of Mental Age gives totally different atmosphere to this game. Msx from "Joe Ripper" is pretty darksome. I like it.
So, why it was changed?
