Yup. You have it right.
Be careful with the traces. They are delicate.

It's a good idea to put a label over the clear window on the EPROM.

I use electrical tape.

I wouldn't. Cutting the middle pins will keep it from working as a 'universal' anypin anymore. You can buy the 6116/6264 anypin for less than the 'universal' anypin. If you get a game that needs a 5101 and you want to use an anypin, you could move this one to it and buy the cheaper one for your MM.

So, to add to John's suggestion, you could get a 24 pin machine pin socket and use it as a "riser". Two SIPs will work too.

Whoops. I literally JUST NOW installed two of these.

Those center pins aren't long enough to impact the MPU board. Good design on Rob's part.
Just insert the NVRAM assembly into the SIPs. You should be good go to.

For future reference, you should put the SIPs on the NVRAM, and then solder the assembled pieces onto the board. This guarantees that the SIP sockets line up with the NVRAM assembly pins.

Why do you cover the window on the chip?

UV light erases eproms. Over time, it's possible some light could get through the window and erase it.

Not saying I've ever *seen* that, but it may be possible, theoretically

Because sunlight can erase the EPROM if the window is open.

Ahh, I never knew that. So why is there even a window on the chip? Was the technology something to marvel at back then? Did they not know this at the time, or just figure they would put the ROM sticker over the window anyway?

The window was put there by design because its rewritable. Expose it to uv light to erase it and then place new rom info on it

http://en.m.wikipedia.org/wiki/EPROM

Because you can run them under a uv light to erase the data and then reuse the chip.

And over time, light from fluorescent tubes (even to so claimed "no UV" ones) could also inflict damage to the data in it.

And while it's extremely unlikely that the whole EPROM will be erased...all it takes is one bit to flip, and the ROM will fail checksum. Then you're done.
