I have a Hamilton ACW-4 that we recently replaced the SRAM (I think that’s what it’s called, has built in battery). Since it lost all its memory we re programmed the prices and tested it with cash. It seems to be working fine with cash now but when you use a card it acts like it’s working but says bay is in use but direction sign inside never lights up and nothing happens in bay. I literally have to go turn power off to reset it. Sorry my explanation isn’t the best.

Need some help with older Hamilton after replacing internal clock chip.

- Start date
So does that mean they won’t service it or you talking Y2K type thing?

So the term “dial up card processing” I’m guessing is an old method. We use crypto pay for the automatic and manual bays. I can call Hamilton Monday I was just hoping someone here had some insight into this. I have seen some previous discussions about guys having to replace the SRAM chip and reprogram the prices. Was hoping this was something simple related to that.
