BackBit Pro Cartridge Adapter

Description

The BackBit Pro Cartridge is a universal instant loading cartridge capable of interfacing with multiple vintage computers via system-specific adapters. All adapters with male edge connectors are 45° chamfered & have immersion gold fingers.

Some adapters can be ordered in different configurations. For instance:

• The Commodore 64/128 adapter comes in a straight and right angle variety. Straight is the most versatile, as it supports vertical slots (like the SX64 & C64GS), and it can stay attached when you open up a breadbin. But right angle is a fashionable option if you want the person over your shoulder to see the cartridge, or you remove the SD card often.
• The VIC 20, Tandy CoCo, and TI-99/4A adapters have adapter cases as an option, as insertion can be fussy. If you want a specific color (Red or Black) be sure to place a note in the comments of your order. Otherwise, I’ll try to match the case color with your cartridge.

Some adapters have advanced features:

• Amstrad CPC+/GX4000 has a chip for ACID protection bypass;
• Atari 5200 has circuitry to utilize a cartridge interlock reset mechanism. If you have an older 4-port system that has not been upgraded, you can instead use a solderless reset jumper;
• Atari 7800 has POKEY emulation via a coprocessor;
• Fairchild Channel F comes attached to a caddy, since insertion would not be possible otherwise;
• Magnavox Odyssey² has The Voice emulation via a 3.5mm output (must extract this file in your SD card’s root);
• MSX has SCC emualtion via a coprocessor;
• TI-99/4A has an electrically switched reset;
• ZX Spectrum and Timex Sinclair 2068 adapters have a Kempston joystick port to hook up an Atari style joystick.

The following adapters include a solderless jumper (one jumper is included, and extra jumpers can be purchased):

• Amstrad CPC+/GX4000 (required for ACID bypass);
• Atari 2600 (optional for reset capability);
• Atari 5200 (optional for reset capability on early 4-port models; not required on 2-port models or “universal” 4-port models);
• Atari 7800 (optional for reset capability);
• Atari 400/800/XL/XE (optional for 1-button reset);
• Bally Astrocade (optional for power if not using USB-C);
