Rework fur den Amiga 2000 bis Revision 4.5
==========================================

Rev 4.0
-------

production start


Rev 4.1
-------

put strobe signal of video connector on to the expansion of the
internal video port (connect U300 pin 18 to CN 203 pin 36)


Rev 4.2
-------

to solve first keystroke problem delete C910/C911


Rev 4.3
-------

For A2620: Add R1000 (470 Ohm from U100 pin 23 to +5V)


Rev 4.4
-------

Noise coupled into RTC osc.

Rerout sensitiv circuit traces:

- remove trace from U801 pin 16 to Y800
- lift U801 pin 17
- add jumper from U801 pin 16 to Y800
- add jumper from U801 pin 17 to C810
- connection already exists, routing critical


Rev 4.5
-------

Add 3k3 Ohm resistor between pin 20 and pin 11 on U605 (74LS245)
