It's a brand of prototyping stripboard. If you want a nasty shock here's some in action :-o  (well, I did say your pic was neater!)

The board looks nice. Look in the A500 mobo to see if there is a near hole you can use to fix your board to the mobo, so you are sure that will not pop-up. (you can also remove the ROM socket and solder directly).

The pins you are going to use to connect your board to the socket should not be to wide or they will destroy the rom socket. I think there is a special kind of conector with round pins of .4 mm or so, look for it if you can. Hope the electronics store near you is better than the one near me !

@Doobrey
Just had a look at your Flash ROM device. IIRC the A1200 Kickstart ROM is 512K? And your device supports 1MB. Does this mean you can flash it with the patched 3.1 ROM from OS3.9 and avoid the setpatch reboot when you cold boot, and have all the new features of OS3.9 even before setpatch?

Hi Amiganew,

Oh, I think I found it.

That is really the original /OE Signal from Board at the socket because in the pickture Flash A500 you can see Three at Carry meaning 19 20 and wr in schematics.

So I need only the signal of Pin 1 or Pin 31 Kickstart at 6a a500 Board

I've just uploaded a pic showing (more clearly) the connections to the Gary chip, for the three IC hooks.
Hopefully it will show up soon for you to see.

If you have a jumper on your Kickstart chip, from pin 1 to pin31, then you can take the signal from either.
If you DON't have a jumper on your kickstart chip, use pin31 for the high order address line.

Let me know if you have any other problems, or something isn't clear.
It's been quite a while since I built it, so I'll probably be a bit rusty with the info.

Cheers,
Red
