I’m waiting several years for a new IDE interface for my Atari (XE/XL) computer, and finally is arrived, compacts, economical and very promising.

some features:

• Is not much greater than a 2,5-inch IDE disk.
• Does not require an external power-supply.
• Contains an XE (CART+ECI) connector, an XL (PBI) connector, a cartridge port, and a connector for a 2,5-inch IDE disk.
• Contains 96 KB ISP Flash ROM and 32 KB RAM available to the internal PBI BIOS and flashable from the Atari.
• Contains 512 KB or 1024 KB ISP Flash ROM for SpartaDOS X (or any other cartridge of such type), flashable from the Atari. This ROM can be physically disabled using a dedicated switch. The switch is not installed in the device shown on photos below.
• Contains a real time clock circuitry to be used with SpartaDOS X. If someone doesn’t want to use it, the module is anyway fully compatible with an external R-Time 8 or internally mounted ARC.
• A LED flashing during the I/O.
