  1. Hi wildstar, I've just tried the v3 eagle .brd file from the github repository and it uploaded and previewed fine with OSH park. Did you download a zip of the whole repository (there is a green clone or download button at the top right of the page)? Robin P.S. I've probably got a few spare PCBs that I never used - PM me if you want me to post you one - it will be cheaper than getting 3 from OSH park if you only wanted one.
  2. Hi Vigo, I wasn't aware of this - thanks for your analysis and suggested fix. Can anyone else confirm instability with 8k ROMs on an 800? I hadn't had any reports of this prior to now which is slightly surprising. Maybe not that many people use the Ultimate Cart on these older machines...? I only have XL and XE machines to test with. Anyway, I'll see if I can find some time soon to test your fix and get the patch committed to the official firmware. Robin
  3. My atari has been away in a box for a bit while I've been playing with other projects, but from memory, it should be sorting A-Z (ignoring case). The only exception to that is that directories will be sorted above files (and again, sorted A-Z). Glad you are enjoying your cart! Robin
  4. Ah, I think I understand... Yes, github doesn't make it that easy to simply download individual files - it kind of expects you to download the whole repository (the green "clone or download" button at the top right when you are on the main page). You could just do that. Or, to download the individual files, you can right-click the "raw" button and then choose "save link as..." (that's in firefox anyway). Robin
  5. That's odd, I've just tested them and they seem to open ok for me in Cura. They also show ok in github's (new?) integrated STL viewer. You are trying to open the STL files? You can ignore the source scad and bmp files in the source subdirectory unless you need to edit the design. Robin
  6. Hi, All the files are there - are you sure you are looking in the right place? https://github.com/robinhedwards/UltimateCart/tree/master/Cartridge%20Shell%20Files Robin
  7. Hi, The Ultimate cart is my design and I have a mac myself. The Ultimate Cart was partially created on a Mac (well, the PCB was anyway). Basically any computer that can read/write a FAT32 SD card (and that includes macs) will be fine for use with the Utlimate Cart. The firmware in the Ultimate Cart also hides all the extra system files that a mac writes on the SD card, so you won't see these clutter up the menu on the Atari. The project is open source, so you could build one yourself if you have the soldering skills. Have a look at https://github.com/robinhedwards/UltimateCart/ for details. Otherwise, if you'd like to just buy one it is currently produced by MacRorie in the USA. His website is http://www.thebrewingacademy.com If he is out of stock, I currently have a spare one which I could sell. Hope this helps, Robin
  8. Hi, Apologies, I meant to do this ages ago. I've attached both the STL file and the OpenSCAD file if you want to make any changes. These are designed to be printed with a layer height of 0.2mm, and a filament change (black -> red) after the second layer (before the lettering is printed). Robin P.S. For those wondering what these files are - the STL file allows you to 3d print a "label" to apply to the top of a standard atari cartridge shell (e.g. combat) which hides any raggedness left when you cut a slot for the SD card. It also has a nice embossed UnoCart logo. Uno-2600.zip
  9. Hi Tane, No risk at all - the file is just loaded into SRAM on the FPGA on boot, in place of the built in 8k cartridge boot rom. It doesn't change the FPGA firmware at all - so delete the file from the SD card and you are back to where you started. There is no way to brick the cart without reporgramming the FPGA, which requires an Altera FPGA blaster. Robin
  10. Hi, Scotland not England thank you! . (Scotland and England are two distinct parts of the larger entity that is the U.K. or Great Britain). I make small numbers of UnoCarts for people in the UK that contact me directly. I'm grateful to MacRorie for making and selling them on a larger scale (with my blessing) since I have little desire to turn my kitchen into a production line (and my wife would not be happy). Robin
  11. Sadly, its not a real filename - just the default hardcoded list in the firmware which I put in for testing/debugging purposes. Robin
  12. Hi, Just for the avoidance of any confusion... the small number of carts I'm producing are uncased, but I'm including a 3d printed top label with a slot for the SD card, so buyers can modify an old cart shell to house their UnoCart-2600 (as pictured above) and make it look nice. MacRorie has designed a nice 3d printed shell with professionally produced labels for his production run, and there is no need to carve up an old shell. Robin
  13. Hi, At the moment, I'm making a smallish number for people in the UK and Europe, but currently demand is ahead of what I've got time to make. I've agreed with MacRorie that he can produce them for the USA/Americas, and he is better set up to make a larger number. Probably best you contact MacRorie, and see if he can provide you some to resell? Or send me a PM? Robin
  14. I'm sure I tested this one on the 7800 i borrowed and it was working fine. Is this a different PAL 7800? Robin
  15. Latest manual is always on github https://github.com/robinhedwards/UnoCart-2600/blob/master/UnoCart-2600-Manual.pdf Reason for the limit - mainly laziness on my part when writing the firmware, it wouldn't be that much work to overcome it. Robin
