- They are confused. With a ROM switcher bending pin 31 up and connecting it to
- pin 21 *may* be needed to keep the two pin 31's from interfering with each
- other. But the ROMswitcher has to connect between pin 1 and 31 for this to
- work on a rev 5.
-
- Rev 6 requires no jumper. If you have a ROM switcher, you may have to bend up
- pin 31 and attach it to pin 21 though. If the ROM came with a jumper from pin
- 1 to 31, it shouldn't need any connection and bending it up should be
- sufficient. But... if it doesn't work, make the 31 to 21 jumper.
-
- If you think this is confusing... you should have had to figure it out!
