Socketed NROM Dev Board

Post by Yoey » Mon Jan 27, 2020 8:13 pm

So, I'm setting out to make a custom little NROM board so I can test projects and all that (I know that flashcarts exist, I just don't have 130 bucks at the moment), For two main reasons:

1. It looks cool
2. I want to test stuff I write and learn about boards

However, my main concern is that after I put sockets onto the board for the EPROMs, they'll be too tall and hit the metal bar on the front loader; Would this be something that happens? If so, how can I work around it? (Thought about just removing the cart slot entirely or using a dremel to take a chunk of the bar out)

In my experience, a single socket fits. Two stacked on top of each other (which you might do to protect the pins on the ROM) don't. ZIF DIP sockets are right out.

A longer board where the ROMs are above the bar might be a nice thing to design.

Yeah, I have a socketed ReproPak board that I sometimes use for testing. The socketed chips won't fit in the cartridge shell (need to make a hole for them) but they do manage to squeak by under the bar, just barely.

...though I later removed the bar entirely because I put in a Blinking Light Win connector, at which point it is no longer even a potential issue.

Have you factored in the cost of an EPROM programmer?

Aside from general browsing shopping sites, not yet-
However, most combinations seem to hit below the 130 mark, so that works out nice I guess

Is it one of those Brazil/Argentina situations where importing a PowerPak requires paying prohibitive import duties but buying a locally made EPROM programmer doesn't?

I've popped the bar out of a couple consoles to accommodate socketed carts. It's a c shape open in the back so you can pull it out towards you with some force. There's no real downside to removing it I'm aware of.

Let's just hope that they slide in right under it, if I need to remove it then that's just what I'll have to do; Thanks all
