Hi, can I have 1st post edit to update the list?

 

Regards: Rafał

 

 

["Dragonfly" preorder]

 

I'm starting the pre-order list for the Dragonfly SD cartridge.

 

 

  

 

 

Technical Specifications

 

Dragonfly supports .a78 files (with header) in sizes 4k, 8k, 16k, 32k, 48k without banking and 64k, 128k, 144k, 256k, 272k , 512k, 528k , 1024k with banking, up to 16kB RAM at address $4000 and POKEY at $4000 and $0450 addresses. Also supports Absolute and Activision. In developer mode, you can also upload .bin files.

 

With the Pokey Max chip it is possible to operate Dual Pokey and Covox.

With the YM module it is possible to operate the Yamaha YM2151 chip.

 

I have more information in the instructions: Manual.pdf

 

Two housing colors are available: burgundy and purple:

  

 

 

The photo is dark, but it renders colors reasonably well.

 

 

The cartridge is modular in design and can be configured upon purchase.
The basic module does not contain the Pokey chip or the YM module, the set includes an SD card and a power cable for the console.
As additional modules, you can buy the Pokey Max chip, the Yamaha YM2151 module and an additional power cable for people with a modified power socket in the console. Due to various standards and the increase in shipping costs, I sell the cartridge without a power supply.

 

View of the PCB with the Pokey Max and YM2151 module installed, as well as an optional power cable:

  

 

 

Costs:
- Dragonfly basic version (without Pokey and YM2151), the set includes a memory card and a cartridge-console cable - 350PLN / $95
- As an additional option, Pokey Max - 160PLN / $43
- As an additional option YM2151 module - 100PLN / $27
- As an additional option, a cable with a 5.5/2.1mm plug (for people who converted the console power supply to a socket in this standard) - 20 PLN / $5
-Shipping 25PLN / $6.5

 

PayPal payment or bank transfer

 

Please report any questions, comments and problems in the "technical thread", please write here only for the purchase. 🙂

On this page you can track the shipment, after sending the package, the tracking will appear next to each nickname: https://emonitoring.poczta-polska.pl/?lang=en

Unfortunately, for most countries, the tracking will stop at WER Warszawa, you have to look for a further route from a carrier in your country.

 

 

 

 

 

 

 

 

["Dragonfly" my version of the Atari 7800 SD cartridge]

The next part of the manual is available for download and should dispel any doubts as to how Dragonfly works.

 

I also inform you that the cartridge may have a different color of the display and / or a different color of the buttons, it is not up to me, but only to my supplier of parts.

["Dragonfly" my version of the Atari 7800 SD cartridge]

The SD card will contain the @Trebor package, some files have been corrected by me.

In the meantime, the user manual is being created, for those interested, I provide the menu structure and developer mode. Later, everything will be integrated and shared with the software.

There will be two color versions of the casing (they are actually darker):

Please, a little more patience, there was a small problem with the USB but I have already located it, fortunately all you need to do is change the value of a few resistors.
By the end of the week I will have a few ready and tested ones, and in a few days I am waiting for the delivery of PCBs and start assembly.
For two weeks my 3D printer has been working 12 hours a day doing casing.

On real hardware it sounds very good, I only have a note for Pokey files for $0450 - the header is wrong and the cartridge is trying to play music for $4000.  You have to set $0x36 in the header to 40 and you'll be fine.  

["Dragonfly" my version of the Atari 7800 SD cartridge]

I would like to ask for a little more patience, today the test cartridge arrived at Walter  
I have a few cartridges ready and material for several dozen pieces, but I am waiting for the results of Dragonfly compatibility with different versions of A7800, if there are no major problems, I will start a new thread for sales only, but here will remain the "technical department".

["Dragonfly" my version of the Atari 7800 SD cartridge]

Let's wait for the results of Walter's tests, I only have two consoles and he has a dozen in all systems  

["Dragonfly" my version of the Atari 7800 SD cartridge]

The works on the final version are almost finished, this week the first cartridge will be sent to a colleague gambler172 for testing.

After the recent changes, Dragonfly supports 1MB files, I also added volume controls for Pokey/Covox and YM2151. USB file loading works.

 

Below is running a 1MB demo - Relax:

 

 

 

 

 

 

[Theoretical Question : Sampled Sound]

Dragonfly has the ability to use interrupts from Pokey or YM2151, this is enabled in the Cartridge Menu. Is that enough?

[sd cartridge for 7800?]

Am not going to quote all the statements, but I will refer to the Pokey + Yamaha topic in general.
Pokey Max is a replacement for the original Pokey and will work in any equipment, it is not imposed anywhere, only for Arcade or XL / XE. Its cheapest and simplest version, i.e. Stereo + Covox, works properly in any gear, it automatically switches to mono mode.
But .... using it in Dragonfly, without incurring additional costs, I also have the option of running a second Pokey and covox, so why not use it? After all, it is at the same price as the mono mode.
The use of Pokey Max is not mandatory, anyone can insert the original or another replacement, and it will work.
There is one more thing, as far as I know, only Pokey Max replacements correctly reproduce all the functions of the original, but in this matter it would have to be spoken by a colleague @Synthpopalooza.

 

As for Yamaha, it is also an additional option, I specially did it on an additional module so that you can decide for yourself about its suitability. Several productions have already been made at YM, and only a few people in the world can run them on their consoles. It's not fair That's why my goal is to make it possible for others to do so, and maybe someone will write something new? The tools for this are already there.

I want my fully decked out DF cart in 7800 purple please?!

 

I have the printer set up for the Fiberlogy filament, so I suggest this color:

And at the moment it's not red, but burgundy, my photos lightened the color too much.

If you really want a choice, I can order and print purple. But be warned, I do not intend to have a whole range of colors to choose from, the complete housing takes about 6.5 hours of printer work  
And I advise against black, it's ugly.

If it uses a separate barrel jack to power it and in turn power to the 7800, then what is the micro usb for below the SD slot? Firmware update?

 

No, the software update for AVR will be from the SD card (bootloader), unfortunately the CPLD from the programmer (I hope there will be no such need). USB is used to transfer game files directly from your computer to SRAM without the need for SD, such a nod to developers. You will be able to set appropriate parameters in the cartridge menu (banking) and transfer .bin files, or set Auto in the menu and transfer .A78 files, the cartridge will read the parameters from the header.
The files on the SD card must be in .A78 format.

 

Huge request, I don't create an order list until the cartridge is tested in its final form. I will let you know when I am sure that it will work properly on many consoles.  

 

Greg2600, the power connector is plugged into the cartridge, and the power supply for the console comes out of the cartridge through this additional cable. Again, I am not a programmer and I will not make a Menu like in Harmony.

In looking at this case design... unless I'm not seeing it, I would suggest adding in additional support for behind the LCD assembly to brace it.

 

And lets get back to the Stereo pokey option? The external audio line is a single channel on the 7800 so all that would accomplish is perhaps allowing more voices than usual with the use of a Pokey or in this case the PokeyMax but you wouldn't actually be able to get stereo left/right channels unless you include a separate audio out that actually mixes the onboard TIA with the external and you connect the audio out from the Dragonfly cart itself instead of from the actual console?

 

Do you mean immobilizing the LCD?

I am not writing Stereo but Dual Pokey, both channels (also with YM2151) are summed into one and in the console again summed up with TIA. As you wrote, it's about increasing channels.

["Dragonfly" my version of the Atari 7800 SD cartridge]

Good idea, I'll add an adder with independent volume control for Pokey/Covox and YM2151.

["Dragonfly" my version of the Atari 7800 SD cartridge]

Time to update.

The redesigned PCB was launched and mostly programmed, unfortunately I made a mistake and I have to correct it again. The photo shows a few cables that I had to save the situation  

 

There was an additional expansion connector that I used for the module from YM2151. Yes, Dragonfly handles Yamaha just like the XM does. The YM2151 module will be available separately as an option.

 

The proof below:

 

In the meantime, I designed the case, this is what it looks like now:

 

It took a while to fix the power connector problem, but it turned out fine.

 

This is what Dragonfly looks like running in the console.

 

Initial valuation at today's exchange rate;
- Dragonfly basic version (without Pokey and YM2151) - 350PLN / $93
- Pokey Max - 160PLN / $42
- YM2151 module - 100PLN / $26

Worldwide shipping will probably be $ 25 / $ 6.5, but I have yet to check it out.

 

When Pokey Max is installed, the Dual Pokey feature will be available at $0440 and Covox at $0430. Interrupts from Pokey and YM2151 are also available.

The USB connector is based on the FT232, so drivers for it are available for every operating system.

 

Due to different power supply standards, no power adapter will be attached to the cartridge, the required voltage is 9V and a current of min. 1.5A, connector 5.5 / 2.1 plus inside.

Can someone explain to me what the 32kB (2x16kB) RAM bankswitch is about? Is there any game or demo that uses this? 

["Dragonfly" my version of the Atari 7800 SD cartridge]

I finally got the ProSystem console so I was able to test NTSC. No problems so far.

 

 

 

 

 

 

 

 

 

The picture is not good because I am using the RF output.

Last year he sent us greetings on the Silly Venture

 

 

Rest in Peace, Curt.

Maria won't exactly mask a pending IRQ, but rather she fully halts Sally during rendering. As long as whatever device is triggering the IRQ will hold IRQn low until acknowledged, Sally can deal with it whenever rendering is over.

 

Regarding sample playback, a small FIFO is a good idea and wouldn't use too many gates. Sally could get an optional IRQ when it's empty, or near empty, and then copy in more sample data when it's convenient for her. I see a small crystal on the board - if it could be clocked by this (with a programmable rate using a phase accumulator), then you don't have to deal with PHI2 wobbling.

 

But again - if you're all continuously going down this route I recommend working together to spec out a new community standard for audio hardware on a CPLD or FPGA rather than it going in a thousand different directions on every new utterance of a flash card or expansion device.

I guess it gets too complex and complicated, it was supposed to be a simple project.

I can also send you a work in progress Danger Zone Rom that has @Synthpopalooza 's funky Pokey special + Tia stuff to test if you like. 

 

Couldn't get it to run on Mateos.

 

Of course, I'll be happy to check it, send it to me at PW.

The first pokey is at $450, and the second pokey is at $460, so you'd either add $10 to your x or y indexes for the second set of voices, or you need duplicate code that more or less fetches the second set of notes using the same indexes but with a different base address.

 

It's worth mentioning the $460 location conflicts with the XM's YM2151 register location, so putting hardware there may rule out XM compatibility for this cart, or at least YM2151 compatibility. If $460 can be entirely taken off the bus when an A78 header flags XM, then things might be ok. (there's still a case where the header doesn't have XM flagged, but may probe for this hardware anyway)

 

I was guided by this: http://7800.8bitdev.org/index.php/XBoard_or_XM_RAM_and_POKEY_banking

I can move the second Pokey to another place, just indicate a free address

I don't know 7800 programming, so I ask if it makes sense. While on the other hand, Covox is in Pokey Max anyway, running it won't cost you anything but a little CPLD code.
As long as I understand the principle of operation, it is enough to write the data to the addresses
$500 for channel 1
$501 for channel 2
$502 for channel 3
$503 for channel 4
and Covox is about to make a sound. But I have no idea how fast you have to do this and whether the A7800 can do it.

Enclosed is music from Millie And Molly, this time with good speed.

 

Back to the Covox, he'll probably be able to get it started on the A7800. I need a free address, one byte is enough. Is $0500 free?
