This optional cable adds full support for ATR files - these using non standard (non system) loading procedures to load data to AVGCART / SUBCART. It also allows to load CAS (tape images) and ATX (copy-protected floppy images).

This will make your AVGCART or SUBCART to load almost 100% of media images available for Atari 8-bit.

Cable is made with injection moulded SIO plug and its length is roughly 30cm. This allows connecting to SIO port in both XL and XE Ataris.
