I’m pretty sure I’ve discovered the problem. I recently bought some CR1225’s in bulk and they were held down to the tray with clear tape.
This left a residue on the top (+) side of the battery, which seems to be enough to intermittently disconnect the power from the SRAM (and hence erase the game-save). I now clean them with acetone.
The battery holder from sparkfun is very similar. Only I use the surface mount version.
Hang on to them, they may be needed for Vaughanabe13’s cart.
and box prints.
I never saw the point of having a box. I don’t supply one with my other carts. But if folks really do want one (so they can get $455 on EBay) they can always buy direct from you.
No box is one thing but no CD with the software either?
Chris makes the boxes. He has them printed at a printers and then assembles them himself. I may be needing some labels for a Vectrex cart I make. I could perhaps do you a deal for a FlashBoy+ if you want ?
All revisions prior to the final version where done with the Eagle router. I decided to buy Electra when Eagle was failing / taking forever.
It’s also cheaper to manufacture if there’s less vias.
using the auto-router… all the ones that I’ve used have sucked, and even if they do route, they look like crap 😉
Doesn’t really matter what it looks like as long as it’s all connected up.
If you spend some time tweaking the settings you can get very close to the look of a hand routed board. Electra can be made do some really neat bus routing.
OK, another batch it is. I just needed to be sure before I bought all the components. It’s a big layout of cash for me if the carts weren’t going to be sold. I don’t know how many folk are still left on the pre-order list (I’ll ask Chris), but I will try and get another 50 made in the next couple of months.
