@ -60,4 +60,8 @@ For best results the boards should be manufactured with the "Gold Fingers" optio
**Solution**: Possible incorrect orientation/faulty ic in U2 - check orientation and/or remove this IC and try again
* **Symptom**: My bridgeboard doesn't work when this card is installed
**Solution**: The bridgeboard needs 512K of the 8MB expansion space for its own use, you will need to move the ram board to the leftmost slot and I recommend flashing the [6MB Firmware](https://github.com/LIV2/GottaGoFastRAM2000/raw/master/Binary/gottagofast2000-6MB.jed) to maximise the amount of memory offered when used with the bridgeboard

* **Symptom**: My system is unstable / graphical corruption when using this board but it passes a memory test in ATK/DiagROM etc
**Solution**: Check that your Amiga 2000 has the correct buffers installed in U600-605. U600,601,603,604 __must__ be 74LS245 and U602/605 should be 74ALS245 but might be 74LS245 in some A2000 revisions.
If you have used anything else (like 74HCT245) for these you will run into issues with this board and many others.
