ECI cable for AVGCART allows expanding your stock 64/128 kB Atari with ECI port (800XE, 130XE, 65XE with ECI) up to 576 kB RAM without opening the computer.
All currently sold AVGCARTs have the needed connector populated, for modding older carts, see https://avgcart.tmp.sk/ecimod/
If you’re ordering this cable separately, please put cable length (shorter/longer) into order notes.
NOTE: When plugging cable to the computer, screw must be on the bottom side.
ECI cable related instructions:
CTRL-SHIFT-M – enable extended ram, setting is persisted to SD card
CTRL-M – disable extended ram
CTRL-SHIFT-E – autoenable, no need to press cart button before pressing reset to go back to selector
CTRL-E – disable autoenable
When ECI cable is detected, ATR emulation is enhanced
- when using SIO cable and HSIO is enabled in cart, HSIO patched OS is forced instead of stock OS (faster ATR loading even on stock machines)
- when not using SIO cable (or with SIO cable connected and launching ATR using SHIFT-RETURN), ATR emulation is done via OS “PBI device” support which is way more compatible than using patched OS loaded into RAM under OS (which is used when no SIO and ECI cable is available)
