- I recently put a Pc-power supply to my old Amiga2000 when it's power
- supply was blown up. I cut a piece of cable and draw that from one of
- those +5 cables to the +5 User pin, (so the current for the +5 User is
- coming from a usual +5 wire), and then I had to change one jumper on the
- motherboard, this jumper is J300, which determines whether the CIA chip
- uses AC line frequency or vertical sync pulse from the video section.
- The tick signal is used for this, so if you change the jumper, you don't
- have to connect the TICK cable. That's it. Now my Amiga works with a Pc
- supply.

- but I hope this text is understandable :-). BUT, I won't take any
- responsibility for this.)
