NTSC A500 Pal/NTSC mod pics

Hi all

i figured it was time to mod my NTSC A500 (V5) for multiregion boot so here it is...

I ran the wires to a jumper block so i can use a regular 2 pin female header block with a switch on it to toggle the modes and also allow unplugging etc. I haven't decided where i am going to mount the switch yet.

I just broke off the pin on the chip and then bent the socket wire back over the socket and then soldered the wires on to each side of the jumper block

Just remember to use pull-up resistor to not fry the Agnus with a floating TTL level and you are set.

Don't bother. All PAL 8372A Amigas have PAL/NTSC pin unconnected. Agnus has internal pullup.
