  • For Sale New Atari ST/E hard disk interface - Faster and more SD card compatible than SatanDisk

    A new bootable low cost Hard Disk interface compatible with Atari ST family computers,
    firmware is refined compared to original one;
    and tested on a 520ST TOS 1.04, 1040STFM TOS 1.04, 1040STE TOS 1.06, 1040STE TOS 1.62 and 1040STE with TOS 2.06; with ok results.

    Results: The ACSI2STM works perfectly; such example loading the 3.5 MB size of current Metal Slug port takes around 6 seconds (aprox. 650 KB/s).
    Tested against old SD cards, such 1 GB card; 4 GB SDHC and 8 GB SDHC. All these are detected and works correctly!

    Operation video,

    A video from the user PSIQ, many thanks!

    Writing and reading from the hard disk interface:

    On the last video, a game running from hard disk is shown; with "/" key, a savestate is created. After successful hard disk file writing, the game is closed pressing "*" key, and the STE system returns to desktop. A copy of the generated GS00.TOS file is created, renaming it to GS01.TOS; finally the game is resumed loading the copy of the savestate, GS01.TOS . All these operations are performed correctly.

    Some images and photographs:

    The bootable hard disk image (DOS & TOS compatible, readable on Windows), can be obtained from atari 8 bit chip ( name: DiskImgPP1 ), or ask when you buy;

    You can use Win32DiskImager (Windows) in order to write it.

    The ST / STE with a hard disk is another world!

    Each unit is completely built and tested,
    price is 34€ + tracked shipment (6€ for Spain or 9€ for Europe; 10€ for America, EE.UU. , Japan, Australia and Canada 11€).

    Lower cost and better SD card compatibility than any Satan disk, and much lower price than UltraSatan.
    Its the Atari ST hard disk suitable for the masses,


    An update, about tested micro SD card brands and types:

    -Micro SD cards that work ok:

    Sandisk de 1 GB
    Kingston 8 GB class 4
    Kingston 4 GB class 4
    Intenso 8 GB class 4
    Intenso 16 GB class 6
    Intenso 4 GB class 10
    Intenso 8 GB class 10
    Kingston 16 GB class 10
    Sandisk 16 GB class 6
    Kingston 1 GB (tested by Shaoth)
    Kingston 2 GB (tested by Shaoth)
    Philips 64 GB UHS-1 A1 V10 Micro SDXC (tested by Shaoth)
    Sandisk Extreme Plus 64 GB UHS-3 Micro SDXC (tested by Shaoth)
    Samsung Evo Plus 128 GB UHS-3 Micro SDXC (tested by Shaoth)

    -Micro SD cards that do not work:

    Cloudisk 512 MB
    No brand 4 GB
    MediaRange 8 GB class 10
    Sandisk 32 GB class 10 UHS 1 (most probably any UHS 1 will fail, due to these reject to operate in 1 bit mode)

    Briefly, Sandisk, Kingston and Intenso are the preferred ones



    You will smile a lot,

    I was waiting until the new firmware is stable for any STM32 version, from original one to clone ones,

    I added DMA transactions for the SD card, using a triple buffer...

    Now the reading speed is near 650 KB/s and writing can reach up to 385 KB/s (when SD card has plenty free space); this device is turning very similar to an UltraSatan, in terms of performance. Maintaining its lower cost nature!

    All users that acquire my manufactured hard disk units, will receive a link with the update file.

                          The image links do not work anymore.

                          Does it need an external power supply?

                            Thanks for reporting the problem with images!

                            Yes, it needs a power supply with a micro USB connector; as mobile phones.

                              Will this be available for some time or is it "now or never"?
