Got in the mail todas! Thank you.

Paid.


Just waiting for shipment...

Hi, that's my picture. Mad#13 is lifted and joined to slot edge connector #48 Hole in mad#13 should be joined with a21 (only in maskrom #0 is needed but I joined both of them) And remember, if you're using that board, the 32mb flash goes to the P1 maskrom hole and the Last 16mb goes to the P0 hole.

PMed

Yes, but the time for battery switch is essential... As a friend explained to me, maybe the sram data is placed too near to the beginning of memory and a slow battery switch could destroy some bits. He made a custom pcb for that game and when using 70ns sram all data are lost, soon or later. All is ...

I can confirm that AST is 100% working in real hardware, both versions 2mb and 4mb.

But there are little issues in saves when the battery outputs are lower than 3,2v. Maybe the sram patch isn't accurate.

Yes, LoRom and 64kb SRAM He's using a pic12F629 instead the binary counter 393, so you can manage the bankswitching more accurate. Where are those wires going to in the back? Do you have a pic of it? Thanks It was a prototype for the AST board final design. They are going to a 12F629... but this is...

Maybe you solved your issue.

Sorry but I didn't see this post until now.

For BJ3M pcb you only need to connect the A21 point in LS139 to MAD pin13 instead the A21 maskrom hole.

Yes, all weeks/parts share the sram data.

Do you ship to Spain?

I would like around 36 units. How much will be?
