ACSI2STM hard drive emulator for 16-bit Atari: ST, STF, STFM, STE, MegaSTE enclosed with case.
This is the latest (and improved) hardware version of the ACSI2STM device in compact size.It is a hard disk emulator for Atari ST (STF, STE, MegaSTE...) based on the ACSI2STM project.
It requires a minimum of TOS 1.04 (this applies to the older Atari ST/STF/STFM). Atari STE TOS versions start minimum from ver.1.62 so all STEs are okay.Also for good work, it requires a minimum of 1 Meg RAM to accommodate the Hard Disk Drivers.
It comes with the Firmware version 5.0a
Improvements compared to the original:

• Solid DB19 ACSI Port - Those who have the 'standard' version will appreciate this,
• Improved SD Card slots - please note that this device has better SD card slots compared to the original. They are push-push so the SDcard sits more firmly compared to the original (Push/pull solution).
• Traces on PCB are wider for less resistance for increased reliability.
• Durable Case Included

Every device is tested before shipment.
What is included:

• ACSI2STM device as pictured,
• ACSI2STM Case for the device as pictured,
• SD card tested with working image, - ASCI2STM is ready to use, plug power, boot and use!

What is needed:

• USB-C power cable,
• USB charger - to fit your USB-C cable (can be any),
• (Optional) - Battery CR2032 to allow RTC Clock to run when the device is off

Please do not use power banks as they cut off power due to small power consumption. You can power ACSI2STM from an external USB charger, or your Atari e.g. with the use of a USB power Cartridge.
Additional information:ACSI2STM is a fantastic open-source project.There are plenty of videos on YouTube on how to use it.
