The!Cart
In October 2013 a new flexible Atari 8-bit cartridge named The!Cart was released. Watch the video below to see what it can do. I support the project with documentation, video tutorials in this youtube playlist, the The!Cart Studio software to create cartridge images of up to 128 MB and support for printing shells.
The!Cart - Features
Emulator: Atari800 This emulator emulates the Atari 8 bit family: 400, 800, 1200XL, 600XL, 800XL, 130XE, XEGS and the Atari 5200. This one of the more tricky emulators to get set up as it requires a multiplicity of BIOS files and configurations depending on what systems you want to utilise but it seems to run Atari 5200 games pretty well. The Atari 400 and 800 were announced in December 1978, though they didn't actually start shipping until late in 1979. Designed to look like a friendly typewriter, the Atari 800 is an expandable system with two easily accessable cartridge ports under a front cover, and a removable top with four expansion slots inside.
At the beginning of the video game and home computer era, the software was primarily released on cartridges. They had many benefits for the consumer:
- Simple to use - plug and play in the original sense of the phrase.
- No additional hardware like a disk drive was required. That was very important at a time when a disk drive was several times more expensive than the computer.
- No loading was required, the program is instantly available when the machine is powered on. Compared to disk or even cassette drives cartridges are infinitely fast.
- No DOS or command line input required.
Cartridges also had benefits for the software producer:
- Mass-production using mask ROMs was cheap.
- Hardware is hard to copy with reasonable effort, so using cartridges inhibited piracy in the beginning.
With the advent of inexpensive disk drives and disks, it all changed of course because it became more attractive for the software producer to release the software on disk. At least until the race between copy protection and crackers was lost. Nevertheless, all the benefits for the consumer are still highly desirable today. And besides that, there are software titles for which the original program is only available on cartridge, for example, OSS Action! or SpartaDOS X. Even new titles are sometimes released as cartridge-only versions, for example, Space Harrier and Atariblast. In most cases, these programs are cartridge-only, because they leverage the possibilities of having several kilobytes up to megabytes of ROM space directly available to the programmer via bank switching. Many software producers in the 80ies even created their individual cartridge hardware and bank switching schemes for the best fit for their software requirements.
Atari 800 Game Roms
And this is where The!Cart comes into play. The unique key feature of The!Cart is the hardware level emulation of 35 different bank switching schemes. No other hardware can currently do that. Combined with the 128 MB of Flash ROM allows you to put basically every ROM release that ever existed for the Atari 8-bit computer on a single cartridge. Via the menu, with the Google-like search, you can easily find the right entry in up to 15.000 ROM files and run the program instantly without any loading.
Besides the native emulation of ROM cartridges, including Atarimax Maxflash compilations, the menu system of The!Cart also supports the emulation of ATR disk image files as read-only disk drives. This way you can basically run any disk-based program also from The!Cart, provided it does not need to write back to the disk. This disk image emulation puts The!Cart also in the category of mass storage media. I've put together an overview of the most prominent mass storage media and their properties. This can help you compare and choose which fits best for you. The products on the SIO port can be combined with the cartridge slot based products. Of course, I cannot put every detail into the overview. So if you have further questions, just post them in The!Card thread onAtariAge.

The!Cart - Questions and Answers
Where can I buy The!Cart?
Atari 800 Cartridge Rom Download
- As of July 2020 a new batch of The!Cart is available in the A.B.B.U.C. Member Shop for 75 EUR. To buy is there you need to be registered in the A.B.B.U.C. Forum and your member ID must be associated with your user account. If that link is missing, just PM one of the A.B.B.U.C. forum moderators.
Does The!Cart work with all Atari 8-bit computers?
- It has been tested successfully on Atari 400 (48k), Atari 600 XL, Atari 800 XL, Atari 1200 XL, Atari 130 XE, Atari 65 XE.
- On the Atari 400 and Atari 800, the cartridge slot lid can only be closed with new smaller The!Cart (2017). If you have a The!Cart (2013), you must leave the lid open and somehow lock the power switch. In all other cases, the shells fit into the regular cartridge slots without problems.
- One problem that was found is an incompatibility with the Atari 800. This incompatibility is not specific to The!Cart but is due to a difference in the pin-out of the Atari 800's left cartridge slot, compared to all other Atari 8-bit machines. The problem can be solved with a very small modification that makes the Atari 800's left cartridge slot compatible with all other Atari 8-bit machines. Click Atari 800 Fix in the menu to read the details.
- There was one case reported where an Atari 8000 XL with built-in U1MB didn't work correctly with The!Cart. As it turned out, the reason was the 74LS08 chip in the Atari which is too slow when more expansions are on the bus. Exchanging it with a standard 74LF08 chip fixed the problem.
- There was one case reported where an Atari 400 with built-in Super Color CPU Card didn't work correctly with The!Cart (2017). As it turned out, the reason is was the change impedance caused by the board. Exchanging the SMD resistor marked with '5K6' on the The!Cart PCB with a 8K2 resistor fixed the problem.
Does The!Cart have gold plated contacts? Naruto to boruto shinobi striker pc local multiplayer.
- The!Cart (2013) did not have gold.
- The!Cart (2017) does have gold plated contacts.
Does The!Cart support the right cartridge slot?
- The!Cart itself is designed for the left cartridge slot, so it is can work the same way in all Atari 8-bit computers. It does not work in the right slot of the Atari 800.
- It can emulate 8k right slot cartridges while being plugged in the left cartridge slot of any Atari 8-bit computer including the Atari 800. Note that the auto-start of right slot cartridges is only supported if the Atari computer uses OS-A or OS-B.
- Because of The!Cart can only emulate one cartridge at a time, it is not possible to emulate a right slot cartridge (e.g. Monkey Wrench) and a left slot cartridge (e.g. ATARI BASIC) simultaneously. But this can be solved by putting both 8 KB ROM files into a single 16 KB ROM file and include that as 'Standard 16 KB' entry.
How limiting is it if you have SIO2USB or SIO2SD instead of SIO2PC for the transfer process?
- Everything is optimized for the best speed on whatever hardware you have.
- Transfer speed is the highest if you use SIO2PC with AspeQt. There a single 128 MB ATR file is created. AspeQt supports up to POKEY divisor 0 with 8k sectors and you can leave the whole thing unattended since no disk change is required.
- A 100% full The!Cart results in 9 ATR files. If you have one of the SIO2USB/SIO2SD devices you can put as many of the ATR files in the virtual disk drives as the device supports. At least 4 are typically supported. If the SIO device supports SIO high speed, i.e. POKEY divisor 3 with 256 bytes sectors, the flasher will automatically use that.
- If only parts of the space are actually used, the respective ATR files and sectors are skipped by the flasher while loading.
How many floppy drives does flasher support for reading the image data?
- The flasher software supports reading from up to 15 drives named 'D1:..D9, DJ:-DO' like in SpartaDOS. At most 9 ATR files are created and you can put them in any of the available drives. If an ATR is not found in any of the drives, you will be prompted to insert it into one of them.
Is there a limit to how many times the Flash ROM can be flashed?
- According to the S29GL01 chip specification, 100,000 program-erase cycles are guaranteed.
Can all disk-based games be loaded?
- It is in the nature of emulating disk drives from ATR images and loading XEX that 100% compatibility cannot be reached without changing the operating system. The reason is that the loading must be somewhere in the RAM and no matter where you put it - there will be one program to use exactly that memory area.
- The loader of The!Cart is very compatible and allows for on-the-fly patching for individual files if required.
- Besides, you can use the very good ATR and XEX loader provided with the Atari Maxflash Studio and put the resulting Maxflash image onto The!Cart.
- With these options combined, The!Cart reaches almost 100% compatibility.
Can disk-based games like Ultima save their state on the cartridge? Recover my files activation key.
- No. The!Cart is a cartridge emulation, not a drive emulation. You can load ATR files with the built-in loader, but they are read-only. Only the flasher program can alter content on the cart.
Can disk-based programs use The!Cart as a RAM Disk?
- Yes. Besides the 128 MB of Flash ROM, The!Cart also contains 512 KB of RAM which are used as buffer memory by the Flasher software and which can also be used as a regular RAM disk under DOS. See the separate page for The!RamDisk driver for details. Because the RAM on The!Cart is in the cartridge area like the Flash ROM, it is only usable by the driver. Programs that require Atari XE compatible extended memory inside the computer (controlled via PORTB of the PIA) will not see the RAM of The!Cart unless they have been patched.
Which sizes are available?
- Originally there were 3 sizes (32 MB, 64 MB and 128 MB) available.
- Meanwhile only the 128 MB version is available. Even the Spansion 128 MB flash chip (S29GL01GT**TF****, for example, S29GL01GP90TFI01) is increasingly hard to get as the whole world moves to serial flash ROMs.
What are RD4/5, S4/5, and CCTL and what do the related LED lights mean to a less technical user?
- The LED lights indicate the status of the control signals on the cartridge ports. See the closeup for the position of the LEDs.
- CCTL indicates there is CPU access to the cartridge control area (bank switching is going on). This LED is not present in the The!Cart V2 anymore.
- RD4/RD5 indicate that the computer currently does see the The!Cart and if it is seen as lower 8k, upper 8k or 16K cartridge.
- S4/S5 indicate that there is CPU access to the lower 8k / upper 8k of the cartridge.
What are some of the advantages you feel The!Cart has over similar products?
- Ultra-fast Google-like search over up to 15.000 entries.
- Hardware-level emulation of 35 cartridge bank switching schemes.
- Compared to Atarimax Maxflash: Almost 128 times space and Atarimax Maxflash can be emulated as well.
- Compared to Ultimate SD: Faster browsing and loading.
- Compared to any SIO or Harddisk-Emulation: Zero loading time for ROM software, practically unbeatable loading speed for disks.
- Build-in 512 KB of RAM usable as RAM disk using The!RamDisk driver.
What are some areas you would like to improve?
- Software:
- Add support for directly loading XEX files without having to wrap them into ATR files or Atarimax Maxflash images.
- Add support for directly playing SAP files. Imagine http://asma.atari.org on The!Cart with the Google-like search - it'd be like Spotify on the Atari :-)
Microsoft monthview control 6 0 excel 2010 download. What should a interested buyer of The!Cart know before purchasing?
- It's probably not the single solution you want. It very convenient for gaming, for other things like data exchange or saving stuff you should still have a SIO2USB, SIO2SD or similar in parallel.
- No ROM emulating solution (Atarimax Maxflash, The!Cart, Ultimate SD) can technically be 100% compatible with all SIO based disk software. Yet here The!Cart is the best level of compatibility.
- To keep the price low, The!Cart is shipped without a shell. You can print your own shell based on the 3D models provided below.
The!Cart V1 Shells
The original The!Cart was delivered with a rather cheap shell in order to keep the overall price low. Sven Pink from the A.B.B.U.C. created the first version of a new 3D printed shell back in 2015, but it was never officially released to the public. Only one prototype was printed back then, which I own. Click on the images to see them in full resolution.
Sven was lacking the time to and I was lacking the skills and equipment to continue the design. So I decided to release the files in 2016 in their current state. Then Bernhard obtained his own 3D printer and started improving the models and creating shells.
Click here to download the OpenSCAD ('.scad') and stereolithography ('.stl') files for printing your own shell for the first version of 'The!Cart'. If you manage to get usable results and maybe create improved versions of the model, I'd be happy to add pictures of your shells here update the download accordingly. You can also visit the corresponding The!Cart Shell thread on AtariAge for questions and feedback. Here's the video on how to move the PCB from the old shell into a new 3D printed shell.
The!Cart V2 Shells
Atari 800 Cartridge Roms
For the second version of 'The!Cart' we provided a 3D print shell from the beginning. Click here to download the OpenSCAD ('.scad') and stereolithography ('.stl') files for printing your own shell. You can also visit the corresponding The!Cart Shell thread on AtariAge for questions and feedback.
The V2 PCB is smaller than the V1 PCB and so is the shell. The V2 PCB also comes with fully gold plated contacts.
The!Cart V2 fits into an Atari 400 and Atari 800 completely, so the lid can be closed. In the pictures below you can see the V2 shell on the left, the V1 shell on the right.
Atari 800 Cartridge Roms
And for those who still prefer classic Atari 800 style shell, I recommend having a look at Wolfsoft's blog. The 'CX4042' label for that mod and the other two labels provided by Mr. Robot are included in the shell download.
Building a retro computer, or even restoring one, is a great way to understand a lot of the fundamentals of computing. That can take a long time and a lot of energy, though. Luckily, there is a Twitter bot out there that can let you experience an old 8-bit Atari without even needing to spin up an emulator. Just tweet your program to the bot, and it outputs the result.
The bot was built by [Kay Savetz] and accepts programs in five programming languages: Atari BASIC, Turbo-Basic XL, Atari Logo, Atari PILOT, and Atari Assembler/Editor, which was a low-level assembly-type language available on these machines. The bot itself runs on a Raspberry Pi with the Atari 800 emulator, rather than original hardware, presumably because it’s much simpler to get a working network connection on a Pi than on a computer from the 80s. The Pi runs a python script that polls Twitter every two minutes and then hands the code off to the emulator.
[Kay]’s work isn’t limited to just Ataris, though. There’s also an Apple II BASIC bot for all the Apple fans out there that responds to programs written in AppleSoft BASIC. While building your own retro system or emulating one on other hardware is a great exercise, it’s also great that there are tools like these that allow manipulation of retro computers without having to do any of the dirty work ourselves.
