Recommended Posts

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 12 seconds (aprox. 650 KB/s read and 400 KB/s write).
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.

Each unit is completely built and tested,
price is 33€ + tracked shipment (6€ for Spain or 9€ for Europe; 10€ for America, Canada, EE.UU. , 11€ for Japan and Australia).


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

-Micro SD cards that do not work:

Cloudisk 512 MB
No brand 4 GB
MediaRange 8 GB class 10

Interesting. It costs about USD$50.00 then, which is quite cheap like you said. Fascinating stuff. Is there tax that needs to be added? Since most people here aren't European Union citizens, I assume there isn't any VAT added. But what about US taxes and tariffs? Are those applicable? Just curious. Thanks. :O)

It's so cool to see.  But I always have trouble with the complexity of these devices.  Is there any kind of guide for adding more software to the SD card after it's been imaged with the winflash utility?  That middle video mentions being able to download whatever you want, but not how to add it to the sd card.

Excuse me the delay...

I understand your worries,

Due to the low size and low weight; the envelope is small and I declare these with a value of 15€

 

However, with this price I can't asume your nation customs taxes, but many do not tax very small declares value such this device

Are you ready to acquire one of these?

Yes, its very easy due to the deployed SD card image is readable under your Windows or Linux machine, as well in your Atari ST/E at once 🙂

 

You only need to use a SD card reader in the PC; its a FAT16 formatted card

 

As well, with the tracking number message I provide ready to use SD card images

Not at present, but I am considering it. I have to think about it. It was a general question. Thanks. :O)

I'm thinking about it now.  I currently have a Gotek drive, which works fine for me.  I'm not sure what extra features this would have for me.

If you use these devices for playing... with a hard disk you can save the game state at any moment, in order to continue playing when you want; for almost any game.

A feature hard to accomplish in a Gotek, due to Gotek is only a floppy replacement, with the limitations of floppy disk size.

 

There is a video of this feature of hard disk adapted games:
