I just checked, the contents of SRAM (especially this old) are completely random and are affected by charge leakage and noise on the bus.

Do we know the SRAM part number(s), the datasheet should have the default value in it?

Did you send a PM?

Wow, painful, AA on 4G.

You have a YouTube channel? 🤯

MCP huh? 😅

Do you have the link, or know what data / address line and resistor value? I am assuming it is either a pulldown or pullup.

I wouldn't make a revised Bob cart, without talking to him first. Which reminds me, I really need to send him an email. If someone has the Choplifter ROM that is fixed, post it here, because I don't even remember that and if that's the case I have to make a new ROM image anyway. 🤪

That's because Windows servers suck, the only merits that Windows has is a large homebrew community and specialty tools for hardware programming that are often far too complicated for regular users under Linux, or they simply don't exist. Albert has a few device programmers that do not work without Windows, he just runs Windows on a Mac to use them. Similarly, I have several hardware programmers that the companies just don't write software for other platforms for, even though they cost about 10 times what a little pissant dual MCU 2600+ board costs.

You are a child and don't deserve help, are you like this to your co-workers as well?

That AMC cart above sure looks like one of mine, I am always trying to make sure to get the copyright correct.

You mean you went and visited someone with a wife and kids, right? 😅

Hard to tell, I'd love to see an angled shot, they look pretty nice.

I found the most expensive parts. 😅 Three tubes even. 🙄

I have parts for hundreds of 7800 carts, just not sure about the 1MB image we made.
